Create Multicast Routes

To handle MLDv1 report packets, you must enable MLD over the interfaces.

1. On routers A and B, enable MLD routing on interfaces.

   SEFOS# conf t
   SEFOS(config)# int vlan 7
   SEFOS(config-if)# ipv6 mld router
   SEFOS(config-if)# end

2. Associate the VLAN 2 interface with PIMv6 component 1.

   SEFOS(config)# interface vlan 2
   SEFOS(config-if)# ipv6 pim componentId 1
   SEFOS(config-if)# exit

3. Associate the VLAN 7 interface with PIMv6 component 1.

   SEFOS(config)# interface vlan 7
   SEFOS(config-if)# ipv6 pim componentId 1
   SEFOS(config-if)# end

4. Enter the interface configuration mode for VLAN 7.

   SEFOS# configure terminal
   SEFOS(config)# interface vlan 7
   SEFOS(config-if)# shutdown

5. Configure the BSR-candidate preference to 20 for the VLAN 7 interface.

   SEFOS(config-if)# ipv6 pim bsr-candidate 20

6. Send the multicast data from host A to router A to populate the source-group entry with the source IP as the IPv6 unicast address of host A and the group address of ff02::e001:0.
7. In router B, associate PIMv6 component 1 with the VLAN 3 interface.

   SEFOS(config)# interface vlan 3
   SEFOS(config-if)# ipv6 pim componentId 1
   SEFOS(config-if)# exit

8. Associate the VLAN 7 interface with PIMv6 component 1.

   SEFOS(config)# interface vlan 7
   SEFOS(config-if)# ipv6 pim componentId 1
   SEFOS(config-if)# end

9. Enter the PIMv6 component mode for PIMv6 component 1.

   SEFOS(config)# ip pim component 1

10. Set the RP-candidate hold time to 30 seconds for PIMv6 component 1.

    SEFOS(pim-comp)# rp-candidate holdtime 30
    SEFOS(pim-comp)# end

11. Set the RP-candidate RP-address for the group in PIMv6 component 1.

    SEFOS(pim-comp)# ipv6 pim rp-candidate rp-address ff02::e001:0  128  7777::21
    SEFOS(pim-comp)# end

12. Send the MLDv1 report message to router B from host B using the source IP of the IPv6 link-local address of host B and the group ff02::e001:0.
13. In router A, review the multicast route table.

    SEFOS# show ipv6 pim mroute
