A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

I have fortinet 600C with WAN interface connected to AT&T router (1 GigE). We are in process to upgrade AT&T MIS circuit from 1Gig to 10Gig. The speed is going to be throttled to 2Gig. What are my options with Fortinet 600C to get 2Gig link speed? Do we have to get two cables going from AT&T or we have to replace the fortinet? What is recommended or what should we do?

My church has a C2851 that has 3 vlans.  It provides DHCP to 2 of those.  The other dhcp is provided by a windows server.  The server vlan never loses connection to the internet but the other 2 access the internet for a day or two then stop until I reboot the router. Below is the interface setup & dhcp pool.  Am I doing something wrong?

We have two HP 5820X switches with an IRF stacked. When putty to the master, I can see the current-running config with all combined config displayed. But how to backup that combined current-running config? Here is my dilemma: if I backup the startup config it will only contains the master switch only.
Also, I found I only can connect to the master but not able to connect the slave. Is it normal?

Hello all. I have a client with a EA-3500 router that I installed a while back. Since the, lots of port customization's were made by another individual. I don't have a record of those modifications. I need to get in and adjust a port. Is there a way of getting in without resetting the device? I have misplaced the UN and PW.  Thanks

Greetings,

I have called up CenturyLink to get my PPPoe username and password, I had them tell me it a few times to avoid typos.

I purchased an ADSL wic on eBay and an 4eswic switch port, I have client that have DSL and want to get them a better option then the cheap routers that you have to reboot often.

Here is the configuration. I have spent time reading many forums and I thought this was correct; however, when I reboot it just shows the ATM0/1/0 as initializing and never does anything. Please help with my configuration. If you see the state of down, nothing is plugged in currently.

Hello all,

I have a group of switches and routers that I would like to be able to run a configuration validation against. We have a set of rules/configurations that we need to ensure is present on our switches and routers, but don't know the best way to move forward with it without looking individually line by line on switches with over 1500 lines of configurations.

Any advice would be greatly appreciated. Suggestions for software would also be appreciated (though, of course, free software is always best :D ).

Thanks!

Router wired to computer nic
Wireless card in computer to communicate with 2  gopros to stream live feed to internet........

can the cameras talk to wireless card w/o ssid... or can create fake "ssid" for cameras and wireless to communicate on .....
Or maybe I am over complicating and should configure router ssid and have cameras talk to server through router and not directly to computer wireless nic......

Was thinking 2 cameras talk wirelessly to wireless card of computer (10.0.0.0) route traffic through wired nic (192.168.69.0) to router - streaming to internet......

Feel like Alice and the Looking Glass.
Sorry for dumb question, just need to bounce this off another geek.  Just feel like there is a piece missing in thought process.

Thanks

Check out ATEN’s VS1912 12-Port DP Video Wall Media Player at InfoComm 2017. Kerri describes how easy it is to design creative video walls in asymmetric layouts and schedule detailed playlists ahead of time with its advanced scheduling feature.

Hello,
I have a customer that wants to extend their wifi network connection to various houses on their land. Each house is about 50 to 80 ft apart. they are using linksys wrt54g routers and repeating their wireless signal from one house to another. so from left to right at-least four houses using wrt54g in each house repeating the ssid. They keep telling me I didn't set it up correctly because they cannot get signal at the last house. I did mention to dig cable not an option and I am not sure how to tell them that the device is obsolete and repeaters through walls and repeating 2500 plus yds wont work unless we dig one cable to center house form first house with router. I just need some words or ideas to inform them that it will not work in easy to understand terms. My explenation of obsolete device, weak frequency channel, this walls and distance is not clear enough I guess. I am not sure anybody has been through this, but i just need some advise on how to inform the customer that the only option is to order more dsl service to their guest houses or dig cable. Also, am i correct for telling them that the devices are old and not reliable? I am installed dd-wrt firmware. I hope this makes sense. thanks for any suggestions

on the topology above , I have R1 and R6 on AS 1, R5 on AS3 , R2,R3,R4 on AS2

I would like to have Routers on AS1 (R1 and R6) Not take route through AS3 to reach routers inside AS2, instead I want AS1 routers to go straight to AS2 through R1 using BGP Default Local Preference command on R1

you can see in the config below on R1 :
bgp default local-preference 600


Below is the BGP route configuration on R1, R6, R3. As you can see R6 is going through AS3 to reach routers in AS2 instead of going straight to AS2 through R1

If you need more info , please feel free to ask.


Thank you

Hi Wizards, I am just wondering about this issue? Can we specify the cost of commands in terms of consuming resource (CPU, RAM) in Cisco devices, such as Routers, Switches?

Many thanks in advance!

See the attached figures.

I have a current configuration that links sites with Point-to-Point (P2P) or MPLS kind of "private" links.
The implementation also provides internet access through the main site for all sites.
(We happen to be using RV042 routers for interfacing with the P2P links).

Now we want to implement VPN tunnels over the links for added security.
(I'm rather sure the RV042s won't support doing this .. for reasons I could get into but need not here and now)

So, the question is:
What simple interfacing routers can I use on the links that will implement the VPN tunnels AND support the intended internet access?
This would end up looking like a NON-split VPN to the linked sites .. i.e. with internet access over the VPN / P2P link.

I need hosts on VLAN 20 to receive multicast packets from address 239.0.1.4 on VLAN 3.  I've read that I need to configure this on the VLAN where is it needed, but I'm not sure if that means to configure it on the source or destination VLAN.

This Procurve is the core router.  How would I make this configuration?

I tried the following, but it did not work.
ip multicast-routing
vlan3
ip pim-sparse ip-addr any
vlan 20
ip pim-sparse ip-addr any

Hello ,

We have a problem with routing instances ;

we are routing some of our ip addresses on firewall filter with next-ip option is that makes latency on high loads ?
We tryed with routing instance but it does not worked , the same config was working on Ex 4500 also

This is what we tryed and not worked :

root@mx80-core# show routing-options rib-groups SPD-Route
import-rib [ inet.0 TCP-Routes-Donus.inet.0 UDP-Routes.inet.0 TCP-Routes.inet.0 TestFW.inet.0 UDP-Routes-Donus.inet.0 DDOSRoute.inet.0 ];


root@mx80-core# show firewall filter FWDirect
term UDPFW {
    from {
        destination-prefix-list {
            Firewall;
        }
        protocol udp;
    }
    then {
        routing-instance DDOSRoute;
    }
}

root@mx80-core# show routing-instances
DDOSRoute {
    instance-type virtual-router;
    routing-options {
        static {
            route 0.0.0.0/0 next-hop 37.123.98.138;
        }
    }
}

Open in new window



then this is what we do :

root@mx80-core# show interfaces xe-0/0/2
unit 0 {
    family inet {
        address 10.10.10.5/30;
        address 37.123.98.137/30;
        address 178.20.227.73/29;
    }
}



term UDPFW {
    from {
        destination-prefix-list {
            Firewall;
        }
        protocol udp;
    }
    then {
        next-ip 37.123.98.138/32;
    }
}

Open in new window


but now we are facing with a latency issue , is that should be the reason ?

Hi,

i have a question concerning the setup of a Dual-WAN environment.

I assume, I have two connections to differen ISPs through two routers with 192.168.1.1 (static WAN IP A.B.C.D) and 192.168.8.1. (static WAN IP E.F.G.H)

Now i would like to setup a Dual-WAN-Router, in order to provide failover and load balancing of these two WAN-connections.

Moreover I host an internal web server behind 192.168.8.1 with a registered Domain for WAN IP E.F.G.H.

How do I setup a Dual-WAN environment, so that webserver is always available?

Is it possible to do that with e.g. Synology Router RT2600ac?

Best Regards

Klaus

How set equally load balancing for 3 different ISPs

Please find the exsting config, after this configuration i am unable to get load balancing in order, always traffice goes automaticly from interface FastEthernet0/0/0 every time i dont know why its happing.

Maximum time uses:-
interface FastEthernet0/1 - 20% (4Mbps Link)
interface FastEthernet0/0/0 - 30% (2Mbps LInk)
interface FastEthernet0/0/1  - 50% (2Mbps LInk)

why every time traffice use primery interface as a interface FastEthernet0/0/1, please suggest what need to be changes for traffice move in order, example:-
interface FastEthernet0/1 - 60% (4Mbps Link)
interface FastEthernet0/0/0 - 20% (2Mbps LInk)
interface FastEthernet0/0/1  - 20% (2Mbps LInk)

Hello every body ,

We have a latency problem with our centos server. We have 2 nic on our cent os one for inbound traffic and one for outbound traffic.

I am routing my 37.123.96.3 ip address to this cent os server. But when i route this ip address there seems no packet loss on the end of 37.123.96.3 but the STDEV - standard deviation  - is getting so high .
Our cent os server's ip address is 37.123.98.138 and when i mtr to 37.123.98.138 directly there seems no high value for stdev and packet loss. But when i check the mtr for 37.123.96.3 there seems so high packet loss on 37.123.98.138 and the stdev value of the 37.123.96.3 is getting so high

there is no iptables rules , cent os server has 32 cores cpu and 64 GB of memory with 10Gbps intel X550 dual nic.

Why that should happen ?

We are routing with juniper mx 80 and the config as given below, 37.123.96.3 has been added to the Firewall prefix list but i do not think it is about a router issue

I cannot ping from R1 to R3 and vice-versa

If I advertize networks 192.168.12.0 and 192.168.23.0 From R2 then I will be able to ping from R1 to R3 and back

Any idea ?

Thanks

What is the process to logon to or reset the logon username and password for a SonicWALL TZ600 router when the logon information isn't known?

We don't want to reset any information on the router we simply want to logon to it or reset the username and password.

We have physical access to this router.

How can this be done?

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
