WB1 9.25 IPv6 PIM and MLD

9.25 IPv6 PIM and MLD

• Enable IPv6 Multicast routing on R1, R3, R4, R5 and R6.
• Ensure PIM does not run on the Frame-Relay link between R4 and R5.
• Configure R5 to join the multicast group FF08::8/128 on its VLAN 58
interface.
• R5 should only accept MLD Reports for the group range FF08::/64 and
should limit the maximum number of multicast states on the interface
towards SW2 to 10.
• Send the general queries every 10 seconds on R5’s VLAN 58 interface.

R1, R3, R4, R5, R6:
ipv6 multicast-routing

R1:
interface Serial 0/1
no ipv6 pim

R3:
interface Serial 1/2
no ipv6 pim

R4:
interface Serial 0/0/0
no ipv6 pim

R5:
ipv6 access-list MLD_FILTER
permit ipv6 any ff08::/64
!
interface FastEthernet 0/0
ipv6 mld access-group MLD_FILTER
ipv6 mld join-group ff08::8
ipv6 mld query-interval 10
ipv6 mld limit 10
--------------------------------------------------

The access-list entry {permit|deny} ipv6 <part1> <part2> allows
for both SSM and normal multicast group filtering.

If you want to filter just MLDv1 joins, leave <part1> as “any” this specifies any source.
The parameter configured in <part2> is responsible for the multicast-group being joined.
