never — Subnet matching is never performed for incoming data packets on this interface.
priority
Syntax priority dr-priority
no priority
Context
config>service>vprn>pim>interface
Description
This command sets the priority value to become the rendezvous point (RP) that is included in
bootstrap messages sent by the router. The RP is sometimes called the bootstrap router.
The priority command indicates whether the router is eligible to be a bootstrap router.
The no form of the command disqualifies the router to participate in the bootstrap election.
Default
1 (The router is the least likely to become the designated router.)
Parameters
dr-priority — Specifies the priority to become the designated router. The higher the value, the higher
sticky-dr
Syntax sticky-dr [priority dr-priority]
no sticky-dr
Context config>service>vprn>pim>interface
Description
This command enables sticky-dr operation on this interface. When enabled, the priority in PIM hellos
sent on this interface when elected as the designateed router (DR) will be modified to the value
configured in dr-priority. This is done to avoid the delays in forwarding caused by DR recovery, when
switching back to the old DR on a LAN when it comes back up.
By enabling sticky-dr on this interface, it will continue to act as the DR for the LAN even after the
old DR comes back up.
The no form of the command disables sticky-dr operation on this interface.
Default
disabled
Parameters
priority dr-priority — Sets the DR priority to be sent in PIM Hello messages following the election

of that interface as the DR, when sticky-dr operation is enabled.
