Point-to-Multipoint RSVP-TE
RSVP-TE signals a P2MP tunnel base that is based on a manual configuration. If all Source-to-Leaf (S2L)s
use an explicit path, the P2MP tunnel creates a static tree that follows a predefined path based on a constraint
such as a deterministic Label Switched Path (LSP). If the S2L uses a dynamic path, RSVP-TE creates a P2MP
tunnel base on the best path in the RSVP-TE topology. RSVP-TE supports bandwidth reservation for
constraint-based routing.
When an explicit path option is used, specify both the local and peer IP addresses in the explicit path option,
provided the link is a GigabitEthernet or a TenGigE based interface. For point-to-point links like POS or
bundle POS, it is sufficient to mention the remote or peer IP address in the explicit path option.
RSVP-TE distributes stream information in which the topology tree does not change often (where the source
and receivers are). For example, large scale video distribution between major sites is suitable for a subset of
multicast applications. Because multicast traffic is already in the tunnel, the RSVP-TE tree is protected as
long as you build a backup path.
Fast-Reroute (FRR) capability is supported for P2MP RSVP-TE by using the unicast link protection. You
can choose the type of traffic to go to the backup link.
The P2MP tunnel is applicable for all TE Tunnel destination (IntraArea and InterArea ). Inter-AS is not
supported.
The P2MP tunnel is signaled by the dynamic and explicit path option in the IGP intra area. Only interArea
and interAS, which are used for the P2MP tunnels, are signaled by the verbatim path option.
