Networking between 10.27.50.x and 192.168.98.x
Hi,
I am setting up a Enterasys XSR-1805 router in a lab environment to be deployed out into our infrastructure.
Currently I have it setup in my office to test with before deploying. Below is the running config for the router:
--------------------------
show run
PLATFORM
CLI version 1.5
XSR-1800
Software:
Version 7.6.0.4, Built Jan 10 2006, 19:20:42
logging timestamp UTC
NETWORK MANAGEMENT
username admin privilege 15 "password is not displayed"
IP LOCAL POOLS
ip local pool dhcp 10.27.50.0 255.255.255.0
exclude 10.27.50.100 50
INTERFACE AND SUB-INTERFACE
interface FastEthernet1
ip address 192.168.98.3 255.255.254.0
no shutdown
interface FastEthernet2
ip address 10.27.50.254 255.255.0.0
ip dhcp server
no shutdown
IP
ip route 192.168.98.0 255.255.255.0 FastEthernet1
SNMP
snmp-server disable
DHCP
ip dhcp pool dhcp
domain-name xxxxx.local
default-router 10.27.50.254
dns-server 192.168.98.195 192.168.98.196
XSR-1805#
--------------------------
The problem is as follows:
On PC#1 with an IP address of (DHCP) 10.27.50.99
I am able to ping the following:
- 10.27.50.99
- 10.27.50.254
- 192.168.98.3
I am NOT able to ping PC#2 with an IP address (STATIC) 192.168.98.99
Worse yet, from the router itself I can ping FastEthernet1 and FastEthernet2, I can also ping PC#1 but CANNOT ping past the interface FastEthernet1.
It is my understanding that once the interfaces have been assigned an IP address and are brought up with the 'no shutdown' command, routing between interfaces is automatic. I am at a loss as to why I can ping all the way across from PC#2 (192.168.98.99) over to PC#1 (10.27.50.99) but cannot even get past interface FastEthernet1 (192.168.98.3) from the router itself.
Any help with this will be greatly appreciated.
Thank-you in advance for taking the time to respond back, I know how busy everyone is!!

Adding in 255.255.254.0 as the subnet mask on the interface will just allow users to hit the 192.168.98.x and the 192.168.99.x subnets correct?

Changing the subnet mask on FastEthernet1 does not have any affect, I am able to ping the interface 192.168.98.3 but cannot ping PC#2 (192.168.98.99)

When you say you cant ping past the interface, can you ping the interface itself from a PC connected on the 192.168.0.x?
ASKER
I can ping the interface (FastEthernet1) from a PC on (192.168.98.99) and a PC on (10.27.50.99). When I am on the router itself, I can ping obviously both interfaces (192.168.98.3) and (10.27.50.254) as well as the PC (10.27.50.99) sitting on the 10.27.50.x subnet. However, the router itself can only ping the interface (FastEthernet1)192.168.98.
The 'IP Route' that I added in "ip route 192.168.98.0 255.255.255.0 FastEthernet1" was removed and re-added, it did NOT make any difference to the results whatsoever.

Any help with this will be greatly appreciated. I am completely baffled as to why it is not routing between networks correctly.

Hi,
One thing that you mentioned got me thinking. I setup another laptop and put it on the same subnet as the one that I couldn't ping to using a cross-over cable. I still couldn't ping so I went in to see if the Windows firewall was turned on or not, it was on!!! I turned off the firewall on both laptops and was able to ping in both directions.
I should have checked this in the beginning but convinced myself it was a router issue, so simple when you go back to the basics!!!
Thanks so much for this, sorry to have bothered you...

INTERFACE AND SUB-INTERFACE
interface FastEthernet1
ip address 192.168.98.3 255.255.254.0
no shutdown
AND
IP
ip route 192.168.98.0 255.255.255.0 FastEthernet1
You have 2 different network masks there for a start
