2. Enter interface view.
interface interface-type
interface-number
N/A
3. Configure the priority for DR
election.
pim hello-option dr-priority priority
Optional.
1 by default.
4. Configure PIM neighbor timeout
time.
pim hello-option holdtime interval
Optional.
105 seconds by default.
5. Configure the prune message
delay time (LAN-delay).
pim hello-option lan-delay interval
Optional.
500 milliseconds by
default.
6. Configure the prune override
interval. pim hello-option override-interval
interval
Optional.
2,500 milliseconds by
default.
7. Disable join suppression. pim hello-option neighbor-tracking Enabled by default.
8. Configure the interface to reject
hello messages without a
generation ID.
pim require-genid
By default, hello messages
without Generation_ID are
accepted.
Configuring the prune delay
Configuring a prune delay interval on an upstream router on a shared network segment can make the
upstream router not perform the prune action immediately after it receives the prune message from its
downstream router. Instead, the upstream router maintains the current forwarding state for a period of
time that the prune delay interval defines. In this period, if the upstream router receives a join message
from the downstream router, it cancels the prune action. Otherwise, it performs the prune action.
To configure the prune delay time:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter public network PIM view. pim N/A
