Fabricpath / HSRPv2

Hello,

 

i have a pair of N7k's connected to each other by fabricpath. Southbound the n7k's are connected to n5k's, also connected by fabricpath. Northbound the n7k's are connected to the ip core routers. The connection to the IP core router is an SVI100 (vlan mode ce) that is attached to a port-channel

I have created a fabricpath vlan 101 on all the switches and the SVI is on both n7k's and i'm running HSRPv2 between the n7k's. The left n7k is the active node.

 

n7k (left)

interface Vlan101
  no shutdown
  vrf member public
  no ip redirects
  ip address 1.1.1.2/26
  hsrp version 2
  hsrp 101 
    preempt 
    priority 105
    ip 1.1.1.1

interface port-channel1
  description peer-link to n7k right
  switchport mode fabricpath
  bandwidth inherit
  vpc peer-link

n7k (right)

interface Vlan101
  no shutdown
  vrf member public
  no ip redirects
  ip address 1.1.1.3/26
  hsrp version 2
  hsrp 101 
    ip 1.1.1.1

 

On both n7k's the arp table is filled. Only from the n7k left i can't ping the 1.1.1.3 with a source ip address from vlan 100 (uplink ce vlan). When i don't use the source vlan 100 ip address, the ping works.

 

Why can't i ping the ip address 1.1.1.3 from the n7k left when i'm using the source ip address from vlan 100?

 

kind regards,

Pascal Lacroix
