Enabling/Disabling MBR
By default, MBR is disabled for the switch. To enable MBR functionality, use the ip mroute mbr
command. For example:
-> ip mroute mbr admin-state enable
To disable MBR functionality for the switch, use the ip mroute mbr command with the disable option.
For example:
.
-> ip mroute mbr admin-state enable
Configuring PIM Route Notification
When MBR functionality is operationally active for the switch (PIM and DVMRP active and registered)
PIM notifies DVMRP about the routes for subnets directly connected to PIM interfaces. To configure PIM
to notify DVMRP about the routes to all multicast sources learned, use the ip pim mbr all-sources
command. For example:
-> ip pim mbr all-sources
To revert route notification back to the default, use the no form of the ip pim mbr all-sources command.
For example:
-> no ip pim mbr all-sources
DVMRP advertises the routes received from PIM within the DVMRP domain using standard DVMRP
mechanisms.
Use the show ip pim sparse or the show ip pim dense command to verify the PIM route notification
method in use. For example:
-> show ip pim sparse
