[c-nsp] Same IP on two interfaces?

[Fedorov, Konstantin]

Hi,

What is the goal of this setup ??

If you configure 2 VRF's, and assign each FE to different VRF's - its
possible have same ip addresses on the router.

Is this common subnet between this FE's ??
If common - impossible, you  receive "duplicated address"

Etherchannel won't work, as it is one router with two interfaces
connecting
to two different switches (unless there is has been a new development
allowing cross-switch Etherchannel, but I don't remember seeing anything
like that).

As others have said, using a BVI and bridge groups should solve this
problem.
