when not to use loopback?

[Mohit Chauhan]

Hi guys,

It seems very simple question, but it made me go thinking and thinking and decided it would be worthwhile to share it here with you.

I am building a small network with one core switch doing all inter vlan routing and connecting to two edge routers (these routers are used for different purpose).

I am planning to use a management vlan having all the switches as part of it. And I was thinking of using loopback interfaces on the routers and use static routing so the core knows where they are located.

My question (which may seem stupid here ) was to ask whether having loopback here would be really worthwhile? or if there is a better way in regards to management of the network devices?

Thanks,

Mo

having a loop back really only makes sense if you have more than 1 path into the router. If you have a single network connection into the switch and that connection goes down, having a loop back wouldn't help much.

Hth,

John
