Cisco Catalyst 2960 / 3560 inter-vlan routing

I'm using a pair of 3560s as core switches, and 5 2960s as edge switches.

In the code segment I've put the running config of one of my core switches, and one of my edge switches.

Once upon a time, I had everything configured and everything was working. I had the 5 edge switches plugged into the 2 core switches, the 2 core switches linked together, and one of the core switches plugged into the production LAN (thus allowing DHCP and internet access).

The DHCP server resides on VLAN1, 192.168.10.0/24 (actual address is 192.168.10.246). All other VLANs are 10.<dept>.0.0/16. For example our systems department resides on the 10.16.0.0/16 subnet.

Well, unfortunately I put them aside after they were configured, waiting for a bunch of new cable to arrive so that I could implement the new switches. I decided to try things out again real quick and make sure that it all works, and sure enough, it does not work.

From both switches I am able to ping the DHCP server via source vlan1, however I am not able to ping via any other source... for example:

SW-CORE-2#ping 192.168.10.246 source vlan1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.10.246, timeout is 2 seconds:
Packet sent with a source address of 192.168.10.203
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms
SW-CORE-2#ping 192.168.10.246 source vlan16

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.10.246, timeout is 2 seconds:
Packet sent with a source address of 10.16.0.201
.....
Success rate is 0 percent (0/5)
SW-CORE-2#

I have not changed anything on my DHCP, or on the switches... but something must've changed?

If you have not changed the config in any way double check that the switches are connected properly and that you are using the proper types of cables for your trunk ports (corssover).

JFrederick29

The DHCP server has a default gateway of 192.168.10.203, right?

The cables in the trunk ports are not crossover, but they were not crossover in my initial setup either -I'm using the same cables, and I've looked several times to make sure that the ports are all connected the same way as they were before.

I created a lot of reference documentation, and also created port descriptions relating to their function.

Okay, so the DHCP server has a route to 10.16.0.0/24 via 192.168.10.202. I assume 192.168.10.202 is the other core switch. Can you post its config?

lunanat

ASKER

Yes, .10.202 is the other core switch (and just in case, I'm gonna say this: There is a route through both .202 and .203, not just .202).

I'm stuck in the middle of a meeting right now that I really don't need to be in, so getting the config will take a bit of time. I'll post it in a few hours when we are finished here.

JFrederick29

I see that configured but looks like it chose the 202 as the preferred.

Make sure you can ping between cores (ping 202 from 203 and vice versa).

At the moment 202 is completely unhooked.. not even powered on. I have 2 core switches with the intent of layer 3 redundancy, allowing a physical hardware failure.

Before I let things sit, I had it configured that things would eventually figure out that the route was dead and failover to the secondary gateway -in my DHCP scope settings, I set 2 gateways for each scope - one for each 3560 switch (the VLAN interface IP address).

hmm... HSRP you say?

I'll read up on that now.

JFrederick29

Easy to implement and works great. Here is an example for VLAN1:

Core1:

interface Vlan1
ip address 192.168.10.202 255.255.255.0
standby 1 ip 192.168.10.1
standby 1 priority 110
standby 1 preempt

Core2:

interface Vlan1
ip address 192.168.10.203 255.255.255.0
standby 1 ip 192.168.10.1

The VLAN1 hosts would have a default gateway of 192.168.10.1 (the virtual HSRP IP).

Interesting.. so then I would only need to configure my DHCP to point to the HSRP virtual IP address as the default gateway on my workstations?

Wouldn't need to configure my edge switches?

JFrederick29

>Interesting.. so then I would only need to configure my DHCP to point to the HSRP virtual IP address as the default gateway on my workstations?

Correct. Core1 (the one with higher priority) would be the active router. If core1 died, core2 would pick up the duties.

>Wouldn't need to configure my edge switches?
This doesn't impact the edge switch configuration. It will remain the same (trunk to both cores).

And I would then on my DHCP server change the routes from 192.168.10.202 and 192.168.10.203 to the new virtual router IP address? As per your example, I would then change the route for say vlan 1 from:
192.168.10.0 255.255.255.0 192.168.10.203 1

to:
192.168.10.0 255.255.255.0 192.168.10.1 1

and vlan 16, following the same conventions, would be:
10.16.0.0 255.255.0.0 192.168.10.1 1
Because the 10.1 ends up pointing to the core switch, which is responsible for routing traffic between the subnets?

JFrederick29

Correct. All routes off the DHCP server subnet (192.168.10.0) would have a next hop of 192.168.10.1.

Furthermore, each subnet/VLAN on the core would have HSRP configured so VLAN16 (10.16.0.x) hosts would have a default gateway of the HSRP virtual IP for VLAN16 (10.16.0.1) for example.

Thank you so much for giving me such a simpler solution than multiple gateways.

As soon as I'm out of this meeting I'll implement!

You rock!

JFrederick29

You're welcome. Good luck.

ASKER

Thank you so much! Not only did you resolve the problem (which in this case was thanks to my half-test and not hooking up the "main" router) you also gave me a much better way to implement my high availability.

Most appreciated.
