EIGRP not advertising a subnet- urgent

prakadeesh · ‎10-09-2009

Hello all,

I have got two SVI interfaces on the 3750, this is the layer 3 switch for those vlans and connectes to other sites. Now I run EIGRP on this 3750 to the other sites. I have say vlan 1 = 1.1.1.0/27 and vlan 2 = 1.1.1.32/27 on this 3750. vlan 2 is a new one that I added.

Now,

* vlan 1 takes part in eigrp

* vlan 2 doesnot take part and any other sites dont have this subnet in the routing table of them.

* checked the show ip eigrp interface on the 3750 and can see vlan 1 and vlan 2 on the interfaces. the eigrp topology on the 3750 also shows that both vlan 1 and vlan2 connected and they are redist in eigrp. I dnt have auto summary in the eigrp.

please help

why is vlan 2 not advertised to next hop?

thanks,

deesh

Hi

We need to see the config of the 3750 and a sh ip route for both vlans as well to start off with.

Cheers

Do have ip classless in your config ???

I agree with Kev that we need additional information to be able to understand what is the problem in your situation. In addition to what he has requested I believe that it might be helpful if you would post the output of show ip interface brief.
