John:
Check your bridging ports.
One of mine was in blocking state.
That broke my ipv6 connection to the bb router.
But i was still able to ping the remote bb2 router.

I reproduced your results.
So now i have the same question.
the ripng process names are identical.
bridge irb
!
interface FastEthernet0/0
description connect to bb2
no ip address
duplex auto
speed auto
ipv6 address 2001:192:10:1::2/64
ipv6 rip RIPng enable
bridge-group 1
!
interface BVI1
ip address 192.10.1.2 255.255.255.0
!
ipv6 router rip RIPng
!
bridge 1 protocol ieee
bridge 1 route ip

Hey Mike,
Tried already without the ipv6 config on the BVI and exactly the
same, got
same config as you on fastethernet. Thinking it's some sort of bug
specific
to the version on my R2 router, can't see anything else wrong with
it. (No
problems pinging it whichever way I do it, purely with getting RIP
routes
when interface is in bridge group).
