Creating a same number vlan on 2 different Routers.

[sanjaynadarajah]

Hi,

My question is it is 'advisable' to create ie) interface vlan 20 with the ip address 172.21.20.0/24 on two routers which is in the same EIGRP AS.

The connection would look something like this :-

RouterA -BB- Core Switch -BB- Router B

I think this will work but it would use the backbone, BB unneccessary a lot. A better idea might be to span the vlan from Router A to the core switch and then connect it to an access switch from there for further usage. This is just my thaught on the connection.

I would like to here from the experts on the advantages/disadvantaes of such a setup.

Thank you,

Hi Sanjay,

There is no problem in doing what you are suggesting. In fact, as you described, this is a more optimal thing to do if you don't want unnecessary traffic across your backbone.

Hope that helps - pls rate the post if it does.
