Creating Multicast Boundaries and Domains
A PIM domain is a contiguous set of routers that all implement PIM and are configured to operate within a common boundary
defined by PIM multicast border routers (PMBRs).
PMBRs connect each PIM domain to the rest of the Internet.
Create multicast boundaries and domains by filtering inbound and outbound bootstrap router (BSR) messages per interface. The
following command is applied to the subsequent inbound and outbound updates. Timeout removes existing BSR advertisements.
● Create multicast boundaries and domains by filtering inbound and outbound BSR messages per interface.
ip pim bsr-border
● Remove candidate RP advertisements.

Enabling PIM-SM Graceful Restart
To enable PIM-SM graceful restart, use the following commands.
● Enable PIM-SM graceful restart (non-stop forwarding capability).
CONFIGURATION mode
ip pim graceful-restart nsf
○ (option) restart-time: the time the Dell Networking system requires to restart. The default value is 180 seconds.
○ (option) stale-entry-time: the maximum amount of time that the Dell Networking system preserves entries from a
restarting neighbor. The default value is 60 seconds.
○ (option) helper-only: this mode takes precedence over any graceful restart configuration.
NOTE:
In helper-only mode, the system preserves the PIM states of a neighboring router while the neighbor gracefully
restarts, but the Dell Networking system allows itself to be taken off the forwarding path if it restarts.
