Candidate RP Message
Some Cisco’s BSRs do not comply with the BSR standards; they do not accept candidate
RPs with a group prefix number of zero. You can configure the router to send candidate
RP messages with the option for the compatibility with the Cisco’s BSR.
To enable the candidate RP message option for the Cisco compatibility, use the following
command.
Enables the candidate RP message option for the
Cisco compatibility.
no ip pim crp-cisco-prefix
Disables the candidate RP message option for the
Cisco compatibility.
Excluding GenID Option
PIM hello messages may contain the generation ID (GenID) in the option fields, which is
a random value for the interface on which the hello message is sent. The GenID is
regenerated whenever PIM forwarding is started or restarted on the interface. It enables
neighbors to quickly detect a router’s reboot and thus to synchronize RP-set information
and forwarding states by triggering the bootstrap and join/prune messages to the
rebooted router. The rebooted router then is able to quickly recover from the reboot.
Some older Cisco’s routers cannot recognize the GenID option in the hello messages, so
the V5808 provides the exclude-GenID option for the compatibility with the Cisco’s
routers.
To exclude the GenID option from the PIM hello messages, use the following command.
Excludes the GenID from the hello messages.
Includes the GenID from the hello messages.
