Before using P2MP LSPs with NG-MVPN, resources must be allocated from the sf-ingress-internal-tcam resource pool using the configure>system>global-res-profile>sf-ingress-internal-tcam>mpls-p2mp command. In addition, if the 7210 SAS-R6 is deployed as a bud router, the configure>system> loopback-no-svc-port p2mpbud p2mpbud-port-id command must be used to configure one of the front-panel ports as a loopback port.
Ingress FC classification is available for packets received on a P2MP LSP on a network port IP interface that needs to be replicated to IP receivers. Ingress FC classification allows users to prioritize multicast traffic to IP receivers in the service. Also available is the capability to mark the packet with IP DSCP values while sending the multicast stream out of the IP interface. To enable ingress FC classification, use the loopback-no-svc-port [p2mpbud p2mpbud-port-id [classification]] command. Before using the command, users must ensure that sufficient resources are available in the network port ingress CAM resource pool and MPLS EXP ingress profile map resource pool. The tools>dump>system-resources command can be used to check resource availability.
