Clearing the PIM Topology Table to Reset the MRIB Connection
No configuration is necessary to use the MRIB. However, users may in certain situations want to clear
the PIM topology table in order to reset the MRIB connection and verify MRIB information.
Beginning in privileged EXEC mode, follow these steps:
Command Purpose
Step 1
clear ipv6 pim [vrf vrf-name] topology
[group-name | group-address]
Example:
Switch# clear ipv6 pim topology FF04::10
Clears the PIM topology table.
Step 2
show ipv6 mrib [vrf vrf-name] client [filter]
[name {client-name | client-name : client-id}]
Example:
Switch# show ipv6 mrib client
Displays multicast-related information about an interface.
Step 3
show ipv6 mrib [vrf vrf-name] route [link-local|
summary | [sourceaddress-or-name | *]
[groupname-or-address [prefix-length]]]
Example:
Switch# show ipv6 mrib route
Displays the MRIB route information.
Step 4
show ipv6 pim [vrf vrf-name] topology
[groupname-or-address [sourcename-or-address]
| link-local | route-count [detail]]
Example:
Switch# show ipv6 pim topology
Displays PIM topology table information for a specific group or
all groups.
Step 5
debug ipv6 mrib [vrf vrf-name] client
Example:
Switch# debug ipv6 mrib client
Enables debugging on MRIB client management activity.
Step 6
debug ipv6 mrib [vrf vrf-name] io
Example:
Switch# debug ipv6 mrib io
Enables debugging on MRIB I/O events.
Step 7
debug ipv6 mrib proxy
Example:
Switch# debug ipv6 mrib proxy
Enables debugging on MRIB proxy activity between the switch
processor and line cards on distributed switch platforms.
Step 8
debug ipv6 mrib [vrf vrf-name] route
[group-name | group-address]
Example:
Switch# debug ipv6 mrib route
Displays information about MRIB routing entry-related activity.
Step 9
debug ipv6 mrib [vrf vrf-name] table
Example:
Switch# debug ipv6 mrib table
Enables debugging on MRIB table management activity.
Step 10
copy running-config startup-config (Optional) Save your entries in the configuration file.
