Do you have anything in the way of COPP on either box that may be
dropping packets? I would imagine the issue is likely to be on the
AS1k end.
Additionally I see you have different interface speeds at each side.
Is the thing in the middle at fault? ND is done using multicast.
One final thing is attempt to ping across the link local addresses.
Make you you set the source address correctly.
I am able to ping the link local address of the 'opposite end' from each
side, so it looks so me like that is working. I also notice, when I try
pinging the 7201 from the asr1000, during that time, the output of 'show
ipv6 neighbors" shows me this:
sh ipv6 neighbors
IPv6 Address Age Link-layer Addr State
Interface
FE80::xxxx:yyyy:FE2D:D190 6 xxxx.yyyy.d190 STALE
Gi0/0.110025
xxxx:yyyy::1:1 0 - INCMP
Gi0/0.110025
It looks to me like enough is 'working' that the asr1000 -> c7201
path is working, but not the other way around. And no, far as I know, I
have no copp or other filtering that would (to my knowledge) create a
one way situation. As far as the middle, I have ip/mpls that is bridging
my vlan25 across the network:
! ME3600x - Facing ASR1000
Interface TenGigabitEthernet0/1
switchport trunk allowed vlan none
switchport mode trunk
mtu 9216
service instance 25 ethernet
encapsulation dot1q 25
rewrite ingress tag pop 1
xconnect 10.0.15.3 2 encapsulation mpls
mtu 9216
!
! ME3600 - facing c7201
interface Vlan25
mtu 9216
no ip address
xconnect 10.0.15.2 2 encapsulation mpls
!
Do I need to make a special provision somewhere for multicast? This
seems pretty basic setup to me.
