Configuring hello options on an interface
Step Command Remarks

2. Enter interface view.
interface interface-type
interface-number
N/A
3. Configure the priority for DR
election.
pim ipv6 hello-option dr-priority
priority Optional.
1 by default.
4. Configure IPv6 PIM neighbor
timeout time. pim ipv6 hello-option holdtime
interval Optional.
105 seconds by default.
5. Configure the prune message
delay time (LAN-delay). pim ipv6 hello-option lan-delay

reject hello messages without
a generation ID.
pim ipv6 require-genid
By default, hello messages without
Generation_ID are accepted.
Configuring the prune delay
Configuring the prune delay interval on an upstream router in a shared network segment can make the
upstream router not perform the prune action immediately after receiving 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 IPv6 PIM view. pim ipv6 N/A
3. Configure the prune delay
interval.
prune delay interval
Optional.
3 seconds by default, which equals
the prune pending time.
