Hello,
I have a 7201 and an ASR1000 and they share a link and run ipv4 and
bgp over it no problem.
I am experimenting and have now added some static ipv6
configuration, and I can't seem to ping across the link. The issue looks
like one side us advertising prefixes correctly and the other isn't.
Here's my interface configs:
ASR1000:
interface TenGigabitEthernet0/1/0.110025
encapsulation dot1Q 25 second-dot1q 11
ip address x.x.x.1 255.255.255.248
ipv6 address xxxx:yyyy::1:1/126
end
7201:
interface GigabitEthernet0/0.110025
encapsulation dot1Q 25 second-dot1q 11
ip address x.x.x.2 255.255.255.248
ipv6 address xxxx:yyyy::1:2/126
end
When I try pinging 7201 from the asr1000, no response. I do see a
neighbor entry on the asr1000:
sh ipv6 neighbors
IPv6 Address Age Link-layer Addr State
Interface
xxxx:yyyy::1:2 0 xxxx.yyyy.8e1b REACH
Te0/1/0.110025
FE80::xxxx:yyyy:FE49:8E1B 0 xxxx.yyyy.8e1b REACH
Te0/1/0.110025
On the 7201 however, there seems to only be the link local address
neighbor entry for the asr1000:
sh ipv6 neighbors
IPv6 Address Age Link-layer Addr State
Interface
FE80::xxxx:yyyy:FE2D:D190 0 xxxx.yyyy.d190 STALE
Gi0/0.110025
Can anyone spot what I am doing wrong?
Mike-
