Configure Point-to-Multipoint for the Source: Example
At the source, multicast routing must be enabled on both the tunnel-mte interface and customer-facing interface.
Then, the static-group must be configured on the tunnel-mte interface to forward specified multicast traffic
over P2MP LSP.
The multicast group address, which is in Source-Specific Multicast (SSM) address range (ff35::/16), must
be used on the static-group configuration because Cisco IOS XR software supports only SSM for Label
Switch Multicast (LSM). Additionally, the customer-facing interface must have an IPv6 address.

There is no difference between logging events at the tunnel level for both P2P and P2MP. The P2MP tunnel
reoptimizes only at the per tunnel level.
