The DR priority command is used to allow a particular router to win the DR
election process by giving a numerically larger DR election priority. The DR
priority option should be included in every hello messages, even if no DR priority
is explicitly configured on that interface. This is necessary because priority-based
DR election is only enabled when all neighbors on an interface advertise that they
are capable of using the DR priority option.
Default priority is 1. The router with the highest priority becomes the DR for the
subnet. The router with the highest IP address becomes DR if there is a tie in DR
priority, the DR priority is not configured, or the DR option is not present. Priority
based DR election is only enabled when all neighbors on an interface advertise
they are capable of using DR priority option. DR is responsible for sending
register packets to RP.
Command (in ICM) Description
ip pim dr-priority <0-
4294967294>
Specifies PIM router DR priority on
an interface. This DR priority is used
in the DR election algorithm.
Default DR-priority is 1.
i
p pim query-interval <0-65535> PIM router sends periodic hello
messages on all PIM enabled
interfaces. Use this command to
configure this interval (in seconds).
The default query-interval is 30
seconds.
ip pim neighbor-filter {< 1-
99 >|< standard access-list-name> }
Enter this command in the Interface
Configuration Mode.
This command is used to prevent
PIM router from forming neighborship
with other router.
Using access-list, you can specify
permitted neighbors.
By default, PIM router forms
neighborship with all the routers on
an interface.
show ip pim rp-hash <group-
address>
This command is used to see group
to RP mapping. If RP information for
the given group does not exist then
command gives error else output
shows the RP information for the
given group.
