To implement IPv6 multicast group address FF70::/12, there are two Cisco IOS XE configurations that are needed:
A. Apply the ipv6 pim command in all interfaces of all IPv6 routers in the IPv6 multicast domain.
The "ipv6 pim" command enables Protocol Independent Multicast (PIM) on the interface. PIM is used for multicast routing and allows routers to forward multicast traffic to the correct multicast group members. By applying this command to all interfaces of all IPv6 routers in the multicast domain, the routers will be able to exchange multicast traffic with other routers in the domain.
D. Apply the ipv6 multicast-routing command in all IPv6 routers in the IPv6 multicast domain.
The "ipv6 multicast-routing" command enables multicast routing on the router. This command needs to be applied to all IPv6 routers in the multicast domain. By enabling multicast routing, the router will be able to forward multicast traffic to the correct multicast group members.
B. Apply the ipv6 pim bsr candidate rp command on the IPv6 routers that announce themselves as RPs and the ipv6 pim bsr candidate bsr command on mapping agent routers only
The "ipv6 pim bsr candidate rp" command designates a router as a candidate for the rendezvous point (RP). The RP is responsible for receiving multicast traffic from the multicast source and forwarding it to the multicast group members. This command needs to be applied on the IPv6 routers that announce themselves as RPs.
The "ipv6 pim bsr candidate bsr" command designates a router as a candidate for the Bootstrap Router (BSR). The BSR is responsible for mapping multicast group addresses to the RPs in the domain. This command needs to be applied on mapping agent routers only.
C. Apply the ipv6 mld ssm-map enable and ipv6 mld ssm-map static command only on the RP IPv6 router.
The "ipv6 mld ssm-map enable" command enables Source-Specific Multicast (SSM) on the router. SSM allows for more efficient multicast routing by enabling receivers to subscribe to multicast traffic from specific sources rather than all sources. This command needs to be applied only on the RP IPv6 router.
The "ipv6 mld ssm-map static" command maps the multicast group address to the specific source address for SSM. This command also needs to be applied only on the RP IPv6 router.
E. Apply the ipv6 pim rp-address command only on RP IPv6 router.
The "ipv6 pim rp-address" command sets the RP address on the router. This command needs to be applied only on the RP IPv6 router.
In summary, to implement IPv6 multicast group address FF70::/12, the following Cisco IOS XE configurations are needed:
