NEXUS 5548 - can't get HSRP nor VRRp to work...

[joyride_us2]

I have my daughter L3 cards installed, features activated and the config is correct...both NEXUS ping each other and are directly connected through a vpc. Still, I land in a split-brain situation : debug shows that they do not receive each other's Hello packets.

Any clue ?

Thanks!

  Is the trunk across the vpc peer link setup  and working correctly ?  you would need to allow any vlans defined across the vpc peer link trunk .

[joyride_us2]

Absolutely.

Have you configured VPC keepalive using mgmt0?

HTH

[joyride_us2]

Yes indee

Check spanning tree then and see if it sees one side as the root  across the peer link , this will tell you if the trunk is ok . Might have to post the config , not a lot to go on .  Nexus is a different beast...

[joyride_us2]

Hmmmmm...none of the Nexus on each side of the peer-link is root for any VLAN.

  Are the layer 2 vlans defined ?  Show vlan on each side to check..  Don't see them in just what you have posted.

[joyride_us2]

Yes they are!
