What happens if a remote leaf losses connection to IPN (and spines)?

[slizarraga]

We have installed a pair for remote leaf, as a VPC domain. They perform the following:

Layer 2 EPG extension

Static routing

OSPF routing

What will happen when one of them losses connection to the IPN network, and through that, to the spines?

I do think ospf routes will be lost, static routing should work; but what about layer 2 extension?

VPC should be broken because they both leaf talk to each other using IPN devices.

Thanks for your help!

Hi

These questions are answered in the Remote leaf white paper in the topic "Failure handling in Remote leaf deployment".

Folks, it worked as suspected. The Layer 3 connections stop propagiting the routes (which have been stop being received) and if there where vpc layer 2 connections, the one from the leaf that lost its uplink went down.
