PIM Sparse-Mode | 529
Enable PIM-SM graceful restart (non-stop forwarding capability) using the command ip pim
graceful-restart nsf from CONFIGURATION mode. There are two options with this command:
•
restart-time is the time required by the Dell Networking system to restart. The default value is 180
seconds.
•
stale-entry-time is the maximum amount of time that the Dell Networking system preserves entries
from a restarting neighbor. The default value is 60 seconds.
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. Enable this mode using the command
ip pim graceful-restart helper-only. This mode takes
precedence over any graceful restart configuration.
Monitoring PIM
The PIM MIB is supported only on platform e
FTOS fully supports the PIM MIB as specified in RFC 5060 with some exceptions.
• The following tables are not supported:
• pimBidirDFElectionTable
• pimAnycastRPSetTable
• The OIDs related to InvalidRegisterMsgs reflect the last received invalid register message. Similarly,
the OIDs related to InvalidJoinPruneMsgs reflect the last received invalid Join or Prune message.
• OIDs which refer to any timer show the time that the timer started; it is 0 otherwise.
