When a router fails to receive subsequent IPv6 multicast data from the IPv6 multicast source S, the router
does not immediately remove the corresponding (S, G) entry. Instead, it maintains the (S, G) entry for a
period of time (namely, the IPv6 multicast source lifetime) before deleting the (S, G) entry.
You can configure common IPv6 PIM timers in IPv6 PIM view or interface view. The configurations made
in IPv6 PIM view are effective on all interfaces and the configurations made in interface view are effective
on only the current interface. If you configure hello message options in both IPv6 PIM view and interface
view, the configuration in interface view always takes precedence.
TIP:
For a network without special requirements, H3C recommends that you use the defaults.
Configuring common IPv6 PIM timers globally
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter IPv6 PIM view.
ipv6 pim [ vpn-instance
vpn-instance-name ]
N/A
3. Set the interval to send hello
messages.
timer hello interval
By default, the interval to send
hello messages is 30 seconds.
4. Set the interval to send
join/prune messages.
timer join-prune interval
By default, the interval to send
join/prune messages is 60
seconds.
NOTE:
This configuration takes effect after
the current interval ends.
5. Set the joined/pruned state
holdtime timer.
holdtime join-prune time
By default, the joined/pruned state
holdtime timer is 210 seconds.
6. Set the IPv6 multicast source
lifetime.
source-lifetime time
By default, the IPv6 multicast
source lifetime is 210 seconds.
Configuring common IPv6 PIM timers on an interface
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Set the interval to send hello
messages.
ipv6 pim timer hello interval
By default, the interval to send
hello messages is 30 seconds.
4. Set the maximum delay for
sending hello messages. ipv6 pim triggered-hello-delay
delay
By default, the maximum delay for
sending hello messages is 5
seconds.
5. Set the interval to send
join/prune messages.
ipv6 pim timer join-prune interval
By default, the interval to send
join/prune messages is 60
seconds.
NOTE:
This configuration takes effect after
the current interval ends.
