Nexus 5548 and VRRP with VPC

Hi everyone.

I've been facing a strange behaviaour configuring VRRP on two NEXUS 5548.

The scenario is as follow

n5k.jpg

Configuration on N5k-1:

interface VlanXXX

  no shutdown
  no ip redirects
  ip address 192.XXX.XXX.2/29
  vrrp 100
    priority 150
    address 192.XXX.XXX.1
    no shutdown

interface port-channel100
  switchport mode trunk
  vpc 100
  switchport trunk allowed vlan XXX

Show port-channel summary

100   Po100(SU)   Eth      NONE      Eth x/y/z(P)

Configuration on N5k-2:

interface VlanXXX

  no shutdown
   no ip redirects
   ip address 192.XXX.XXX.3/29
   vrrp 100
     address 192.168.200.1
    no shutdown

interface port-channel100

  switchport mode trunk

  vpc 100

  switchport trunk allowed vlan XXX

Show port-channel summary

100   Po100(SU)   Eth      NONE      Eth x/y/z(P)

What happen is that from the "OTHER SWITCH" I can't ping the VRRP address but I see the complete arp; and of course I can't reach LAN A.

If I use the vlan XXX address on N5k-1 as next hop to reach LAN A everything works properly.

ANY IDEAS/SUGGESTION TO SOLVE IT??

PS: the release on both N5k is n5000-uk9.5.0.3.N1.1c

UPDATE: even with HSRP instead of VRRP the behaviour is the same

Hi,

Do the nexus have installed the L3 daughter card? and the L3 license? That could be the problem...

Can you paste a show module and show license commands?

Regards,

Jose.

Hi,

The L3 daughter card and licenses have been already installed properly.

We've found out that somehow the Nexus looses the licensed feature after a reload.

We had to uninstall the licenses and install them back.

This behaviour is under observation by TAC now.

Thanks for answering, I'll give un update as soon as possible
