Operation
Resets the delay interval for triggering LAN prune
delay packets on the interface. (Default: 500
milliseconds)
dr-priority
Resets the priority of the interface in the Designated
Router election process. (Default: 1)If you want one
router on a given VLAN to have a higher priority for
DR than other routers on the same VLAN, use the
dr-priority
command to reconfigure the DR
priority setting as needed. Otherwise, the highest DR
priority among multiple routers on the same VLAN
interface is assigned to the router having the highest
source IP address for PIM-SM packets on that
interface.
Applies to both PIM-SM and PIM-DM operations.
Router Pim configuration
These steps configure the PIM-SM in the Router PIM context (
switch (pim)#_
).
Procedure
1.
Specify the VLAN interface to advertise as the BSR Candidate and enable the router to advertise itself as a
candidate BSR in a PIM-SM domain. (Use
bsr-candidate source-ip-vlan
vid
.)
2. Option
: To make NSR candidate selection occur quickly and predictably, set a different priority on each BSR
candidate in the domain. (Use
bsr-candidate priority
.)
3.
Do one of the following to configure RP operation:
a. Recommended
: Enable C-RP operation and configure the router to advertise itself as a C-RP to the BSR for the current
domain. This step includes the option to allow the C-RP to be a candidate for either all possible multicast
groups or for up to four multicast groups and/or ranges of groups. (Use
rp-candidate source-ip-vlan vid [group-addr/group-mask].)
b. Option:
Use
rp-address ip-addr [group-addr/group-mask]
to statically configure the router as
the RP for a specific multicast group or range of multicast groups. (This must be configured on all RIM-SM
routers in the domain.)
4. Option
: In the PIM router context, change one or more of the traffic control settings.
