Hello I have some non cisco routers running vrrp between three sites (Router 1, Router 2, Router 3. The same server vlan resides at all three sites. Currently spanning tree is blocking the link between Router 2 and Router 3. I want to attach two nexus 7000s (connected currently to each other with vPC peer links) to router 1 and router 2 and also have this same server vlan reside on each nexus. I am unsure the best way to link the two nexus's to Router 1 and 2.
To vPc or not and where will spanning tree kick in with all of these different paths?
Note: I need to keep VRRP routing only between router 1, 2 and 3 as the existing network needs to be able to function without the Nexus's. At some point the nexus's may be disconnected for an extended duration.
Thanks for the help
