Monitoring Multicast Routing and Forwarding

Context

During routine maintenance, run the following commands in any view to check the running status of the multicast forwarding and routing tables.

Procedure

Run the display multicast [ vpn-instance vpn-instance-name | all-instance ] boundary [ group-address [ mask | mask-length ] ] [ interface interface-type interface-number ] command to check the multicast boundary configured on an interface.
Run the display multicast[ vpn-instance vpn-instance-name | all-instance ] forwarding-table [ group-address [ mask { group-mask | group-mask-length } ] | source-address [ mask { source-mask | source-mask-length } ] | incoming-interface { interface-type interface-number | register } | outgoing-interface { include | exclude | match } { interface-type interface-number | register | none } | { statistics | verbose } ] ^* command to check the MFIB.
Run the display multicast routing-table [ vpn-instance vpn-instance-name ] static [ config ] [ source-address { mask-length | mask } ] command to check the multicast static routing table.
Run either of the following commands to check the multicast routing table:
- display multicast { vpn-instance vpn-instance-name | all-instance } routing-table [ group-address [ mask { group-mask | group-mask-length } ] | source-address [ mask { source-mask | source-mask-length } ] | incoming-interface { interface-type interface-number | register } | outgoing-interface { include | exclude | match } { interface-type interface-number | register | none } ] ^* [ outgoing-interface-number [ number ] ]
Run the display multicast [ vpn-instance vpn-instance-name | all-instance ] rpf-info source-address [ group-address ] [ rpt | spt ] command to check the reverse path forwarding (RPF) route.
