Hi all out there.
I have to build up connection between two pairs of Nexus7K (M3-Linecards running 8.1) via vPC
I have to have L2 trunk over the vPC and dynamic-routing (OSPF) as well. (Transfer VLANs enabled on vPC and SVIs on the vPC-Peers)
So far so good , dynamic routing over vPC is supported since 7.2 whith configuring
"layer3 peer-router" under vPC.
Unfortunately I need also PIM Adjacency over these L3-Transfer-VLANs for MC-routing.
I found out now that PIM adjacency via a vPC-VLAN is not supported..
I do not have the chance to have seperate L3-Links between the vPC-Pairs, I have only the fiber-links for building the vPC between them.
So my idea was to build up the vPC as I palnned it before, but I do not create SVIs for the L3-Transfer-VLANs.
I want to configure a routerd interface (with routed Subinterfaces for all the needed Transfer-VLANs)
and connect this L3-Interfae locally on every Box to a L2-trunk which carries only these "Transfer-VLANs".
With this trick can I go arround the PIM adjacency Limitation ver vPC.
Would this be a valid Option ??
Thx in Advance for discussing this
