Hi,
I'm having trouble forwarding packets between two IPv6 islands in a simple setup. The control plane seems to be working fine as i'm learning the routes in each of the CEs but can't ping the remote CE from the local CE and vice versa.
Here's my topology:
C3---R5---R7---R8---P1
C3 lo0.3 - fd18:cccc:dddd:2:f::1/128
P1 lo0.36 - fd01:aaaa:bbbb:0:f::1/128

As you can see, i'm learning the routes via BGP in each of the CEs but ping from one loopback to another is not working.
root@C3# run ping fd01:aaaa:bbbb:0:f::1 source fd18:cccc:dddd:2:f::1
PING6(56=40+8+8 bytes) fd18:cccc:dddd:2:f::1 --> fd01:aaaa:bbbb:0:f::1
^C
--- fd01:aaaa:bbbb:0:f::1 ping6 statistics ---
10 packets transmitted, 0 packets received, 100% packet loss
Any help would be greatly appreciated. Thanks!
