I don't believe that a BVI supports IPv6. I'd try to put it through a GRE
tunnel!

Guys,

Can anyone explain to me why this isn't working?

R2 FE0/0 is connected to BB2 E0, speaking IPv6 rip and sending IPv6 RIP
routes to BB2, which is seeing and installing them in it's route tables.

R2 FE0/0 is part of a bridge group (Not in use for this section). If I put
the config on the BVI interface I don't recieve any IPv6 RIP routes from BB2
. If I put the IPv6 config on the fastethernet I get exactly exactly the
same results (In the answer key the config is on the fastethernet, not the
BVI).

If I remove the interface from the bridge group it all springs into life, if
I re add it then same again. Rebooted also to see if that fixed anything.

Have the following config on R2:

interface BVI1
 ip address 192.10.1.2 255.255.255.0
 ipv6 address 2001:192:10:1::/64 eui-64
 ipv6 rip RIPng enable
end

or alternately (Removing from FA0/0):

interface FastEthernet0/0
  no ip address
  ipv6 address 2001:192:10:1::/64 eui-64
  ipv6 rip RIPng enable
  bridge-group 1
end

On BB2 it's:

interface Ethernet0
 ip address 192.10.1.254 255.255.255.0
  ipv6 address 2001:192:10:1::254/64
 ipv6 rip RIPng enable
end
!
ipv6 router rip RIPng
  distribute-list prefix-list RIPng out
!
ipv6 prefix-list RIPng seq 5 permit 2001:205:90:31::/64
ipv6 prefix-list RIPng seq 10 permit 2001:220:20:3::/64
ipv6 prefix-list RIPng seq 15 permit 2001:222:22:2::/64

(These are the routes I'm expecting to see)

Some debugs:

Am I just banging my head against a bug or am I missing something blindingly
obvious?
