Hi John:
Remove the ipv6 configurations from the bvi interface.
You must have a duplicate ip address error.
I configured this using only the fastethernet0/0 interface and it works.
!
interface FastEthernet0/0
description connect to bb2
no ip address
duplex auto
speed auto
ipv6 address 2001:192:10:1::/64 eui-64
bridge-group 1
end
R2#ping 2001:192:10:1::254
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001:192:10:1::254, timeout is 2
seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms

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)

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