Cisco ASR 920 series Configuration

•
Two destination lists are specified, one for dynamic paths and one for explicit paths. The destination
list specifies one path-option per destination.
•
Thetunnelmodemplstraffic-engpoint-to-multipoint command enables the P2MP tunnel.
•
On the tunnel interfaces, the ippimpassive command is used.
•
On the non-MPLS interfaces, the ippimsparse-mode command is used.
•
The ipigmpstatic-group commands map the multicast groups to the P2MP tunnel.
•
FRR is enabled on the router, with tunnel 3 as the backup path. An explicit path called PE5->P1-BKUP
provides the alternative path.
