Move
ipv6 address 2001:192:10:1::2/64
ipv6 rip RIPng enable
to the BVI interface. That will do the trick.

Subject: Can't receive RIPng routes on LAN interface configured with
"bridge-group" command
Hi Group,
I have the following IPv6 RIPng scenario:
R2 (fa0/0) -----VLAN22----- (fa0/0) BB2
R2:
!
ipv6 unicast-routing
bridge irb
bridge 1 protocol ieee
bridge 1 route ip
!
interface FastEthernet0/0
no ip address
bridge-group 1
!
interface BVI1
ip address 192.10.1.2 255.255.255.0
!
BB2:
!
interface FastEthernet0/0
ip address 192.10.1.254 255.255.255.0
ipv6 address 2001:192:10:1::254/64
ipv6 rip RIPng enable
!
interface Loopback0
ipv6 address 2001:220:20:3::1/64
ipv6 rip RIPng enable
!
interface Loopback1
ipv6 address 2001:222:22:2::1/64
ipv6 rip RIPng enable
!
interface Loopback3
ipv6 address 2001:205:90:31::1/64
ipv6 rip RIPng enable
!
Outputs of "deb ipv rip" on BB2:
RIPng: Sending multicast update on FastEthernet0/0 for RIPng
src=FE80::21B:54FF:FECE:1F84
dst=FF02::9 (FastEthernet0/0)
sport=521, dport=521, length=72
command=2, version=1, mbz=0, #rte=3
tag=0, metric=1, prefix=2001:220:20:3::/64
tag=0, metric=1, prefix=2001:222:22:2::/64
tag=0, metric=1, prefix=2001:205:90:31::/64
However, R2 did not receive those RIPng routes from BB2 until I removed the
"bridge-group 1" command from its Fa0/0 interface.
Anyone be kind enough to explain why and advise a solution. The bridge group
can't be removed because that will violate the requirement of an earlier task.
Thank you.
BR,
Emil
