All,


I have IPv6 enabled on two SVI's that are on 6509's. They are in an HSRP group. I have implemented this configuration for our customers before, but this time, one of the actual v6 addresses are unpingable, and that same is not showing that it has joined the the HSRP solicited node multicast address. When I do a show standby for this interface, the two SVI's are communicating, because the output shows this as such. When I try to ping from the affected interface I receive this:


% No valid source address for destination


When I do a show ipv6 interface vlan xxx, i get the following for the problematic interface



Vlanxxx is up, line protocol is up

  IPv6 is enabled, link-local address is FE80::223:ACFF:FE88:CC00 [UNA]
  Virtual link-local address(es):
    FE80::5:73FF:FEA0:3C [UNA/OOD/TEN]
    Global unicast address(es):
    xxxx:xxxx:xxxx::1, subnet is xxxx:xxxx:xxxx::/64 [UNA/OOD/TEN/VIRT]
    xxxx:xxxx:xxxx::2, subnet is xxxx:xxxx:xxxx::/64 [DUP]
  Joined group address(es):
    FF02::1
    FF02::2
    FF02::66
    FF02::1:FF88:CC00
  MTU is 1500 bytes
  ICMP error messages limited to one every 100 milliseconds
  ICMP redirects are disabled
  ICMP unreachables are disabled
  ND DAD is enabled, number of DAD attempts: 1
  ND reachable time is 30000 milliseconds
  Hosts use stateless autoconfig for addresses


I receive no reply when attempting to ping this interface, but I do receive a reply when I ping the HSRP ipv6 address, and the other ipv6 address on the other switch.


The below output show the HSRP state for the problematic interface:


Vlanxxx - Group xx (version 2)

  State is Standby

    4 state changes, last state change 06:11:01

  Link-Local Virtual IPv6 address is FE80::5:73FF:FEA0:3C (impl auto EUI64)

    Virtual IPv6 address xxxx:xxxx:xxxx::1/64

  Active virtual MAC address is 0005.73a0.003c

    Local virtual MAC address is 0005.73a0.003c (v2 IPv6 default)

  Hello time 3 sec, hold time 10 sec

    Next hello sent in 0.800 secs

  Authentication MD5, key-string

  Preemption enabled

  Active router is FE80::223:ACFF:FE35:E000, priority 110 (expires in 9.504 sec)

    MAC address is 0023.ac35.e000

  Standby router is local

  Priority 105 (configured 105)

  Group name is "hsrp-v6-v419-01" (cfgd Vlanxxx - Group xx (version 2)
  State is Standby



Any ideas?


Thanks
