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 the 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 ] ] command to check the multicast routing table.
- 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.
