The configuration on Router A and Router B is similar to that on SecPath A. The configuration on
SecPath B and SecPath C is also similar to that on SecPath A except that it is not necessary to
enable MLD on the corresponding interfaces on these two routers.
3.
Configure the IPv6 SSM group range:
# Configure the IPv6 SSM group range to be FF3E::/64 on SecPath A.
[SecPathA] acl ipv6 number 2000
[SecPathA-acl6-basic-2000] rule permit source ff3e:: 64
[SecPathA-acl6-basic-2000] quit
[SecPathA] pim ipv6
[SecPathA-pim6] ssm-policy 2000
[SecPathA-pim6] quit
The configuration on Router A, Router B, SecPath B and SecPath C is similar to that on SecPath A.
4.
Verify the configuration:
Use the display pim ipv6 interface command to display IPv6 PIM information on each interface of
firewalls. For example:
# Display IPv6 PIM configuration information on SecPath A.
[SecPathA] display pim ipv6 interface
Interface NbrCnt HelloInt DR-Pri DR-Address
GE0/1 0 30 1 1001::1
(local)
GE0/2 1 30 1 1002::2
GE0/3 1 30 1 1003::2
Assume that Host A needs to receive the information a specific IPv6 multicast source S
(4001::100/64) sends to multicast group G (FF3E::101). SecPath A builds an SPT toward the
multicast source. Routers on the SPT path (SecPath A and SecPath B) have generated an (S, G)
entry, but SecPath C, which is not on the SPT path, does not have multicast routing entries. You can
use the display pim ipv6 routing-table command to display PIM routing table information on each
firewall. For example:
# Display IPv6 PIM multicast routing table information on SecPath A.
[SecPathA] display pim ipv6 routing-table
Total 0 (*, G) entry; 1 (S, G) entry
(4001::100, FF3E::101)
