Dynamic routing issue

[Bruno Silva]

Hello,

well, my question is: I have one central route (Cisco Catalyst 3750G-48TS-S) and twenty Switch with layer three ios (Cisco 3560G-24) conected in star topology....

What i want to know is, how central router can communicate with just another router (Cisco 1841) that is behind any 3560G layer three switch?

the cisco 1841 is always the same router that could be behind any other cisco 3560G switch.

Thanks a lot for your patience!

Hmmm..I've only done it once, and that router isn't in production. You should start another discussion for that. There are others on here that are more experienced with 3G cards in the router.

HTH,
John

On the 3750 I have sub interfaces on port channel 1 for all my 3560 connections. On 3750 router I have just to ports to connect to all my 20 3560 Layer 3 switches, I put all the 20 Vlan on port-channel and configured port-channel on g0/0 and g0/1.

I used trunk links on my 3560 because they are connected (g0/24) to backbone by alcoate equipment to 3750 router.
