Hi, I have two routers r1 and r2 connected to a switch with GigE ports:
r1[Gi] <-> switch <-> [Gi]r2 r1 and r2 are in the same broadcast domain. According to "sh ipv6 interface" command, first router has IPv6 address 2001:10:7::4 and second one has IPv6 address 2001:10:7::3: Global unicast address(es): 2001:10:7::2, subnet is 2001:10:7::/64 [OOD/VIRT] 2001:10:7::4, subnet is 2001:10:7::/64 Global unicast address(es): 2001:10:7::2, subnet is 2001:10:7::/64 [UNA/OOD/VIRT] 2001:10:7::3, subnet is 2001:10:7::/64 In addition, as you can see above, GigE interfaces in both routers have VRRPv3 configured: vrrp 1 address-family ipv6 address FE80::250:56FF:FEA8:5E6C primary address 2001:10:7::2/64 exit-vrrp While overall IPv6 connectivity, VRRP and IPv4 connectivity between the routers works fine, the IPv6 one does not: r1#ping ipv6 2001:10:7::3 source 2001:10:7::4 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 2001:10:7::3, timeout is 2 seconds: Packet sent with a source address of 2001:10:7::4 .H..H Success rate is 0 percent (0/5) r1# Is it possible that VRRP restricts hosts to reach each other on IPv6? Unfortunately, I do not have another pair of routers besides those live ones which support VRRPv3.. regards, Martin _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
