Context Operation

propagation-delay*
(page 4-33)
dr-priority
(page 4-33)
Resets the override interval of the LAN Prune Delay
configured on the interface. (Default: 2500 milliseconds)
Resets the delay interval for triggering LAN Prune Delay
packets on the interface. (Default: 500 milliseconds)
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 operation.
Router PIM Configuration
These steps configure PIM-SM in the Router PIM context ( ProCurve(pim)#_).
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. Optional: To make BSR candidate selection occur quickly and predictably,
set a different priority on each BSR candidate in the domain. (Use bsr­
candidate priority — page 4-36.)
3. Do one of the following to configure RP operation:
• Recommended: Enable C-RP operation and configure the router to
advertise itself as a candidate 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 ].)
• Alternative or Additional Option: Use rp-address < ip-addr > [ group­
addr/group-mask ] to statically configure the router as the RP for a
specified multicast group or range of multicast groups. (This must be
configured on all PIM-SM routers in the domain.)
