Huawei quidway s7700 - Monitoring the Status of Multicast Routing and Forwarding

Context
CAUTION
The reset command clears the entries in the multicast forwarding table or the multicast routing
table. It may result in abnormal multicast information forwarding. After the routing entries in
the multicast routing table are cleared, the corresponding forwarding entries corresponding to
the public network instance or VPN instance are also cleared. So, confirm the action before you
use the command.
Procedure
l Run the following commands to clear the forwarding entries in the multicast forwarding
table.
– reset multicast [ vpn-instance vpn-instance-name | all-instance ] forwarding-table
all
– reset 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 } }
*
l Run the following commands to clear the routing entries in the multicast routing table.
– reset multicast [ vpn-instance vpn-instance-name | all-instance ] routing-table all
– reset 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 } }

9.7.4 Monitoring the Status of Multicast Routing and Forwarding
During the routine maintenance of IPv4 multicast routing management, you can run the display
commands in any view to know the running of the multicast forwarding table and routing table.
Context
In routine maintenance, you can run the following commands in any view to check the status of
multicast routing and forwarding.
Procedure
l Run the display multicast [ vpn-instance vpn-instance-name | all-instance ] boundary
[ group-address [ mask | mask-length ] ] [ interface interface-type interface-number ]
command in any view to check the multicast boundary configured on an interface.
l Run thedisplay multicast [ vpn-instance vpn-instance-name | all-instance ] forwarding-
