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)

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

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

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
