vPC w/ HSRP and default route on one vPC peer only

Hi all,

I've got the following issue currently in a lab, but want to deploy at some stage.

Situation is this: Only one of the vPC peers has the interface with the default route, so when the other vPC member is the HSRP active, vPC members forwarding to the vPC peer that doesn't have the default route isn't able to forward traffic to the default route. I've tried to resolve this by using OSPF between the vPC peers and advertising the default route that way to no avail - layer 3 peer-gateway has been configured on the vpc domain.

Traffic forwards fine when the vPC peer with the default route is the HSRP active gateway.

Any pointers/suggestions welcome.

Edit: I think I may have found the answer..

" Figure 60. Layer 3 and vPC Unsupported Designs: Peering Over a vPC Interconnection "

Suggestion is to create a separate layer 3 link for routing and not the vPC peer-link. I'll play around again later and post back.
