18.1.3.8 ipv6 pim state-refresh origination-interval
Command: ipv6 pim state-refresh origination-interval <interval>
no ipv6 pim state-refresh origination-interval
Function:
Configure transmission interval of state-refresh message on interface. The “no
ipv6 pim state-refresh origination-interval” command restores default value.
Parameter:
<
interval
> message transmission interval value is from 4s to 100s.
Default:
60s
Usage Guide:
The first-hop router periodly transmits stat-refresh messages to maintain
PIM-DM list ltems of all the downstream routers. The command can modify origination
interval of state-refresh messages. Usually do not modify relevant timer interval. The
command can configure on IPv6 tunnel interface, but it is successful configuration to only
configure tunnel carefully.
Example:
Configure transmission interval
of state-refresh message
on interface vlan1 to
90s.
Switch (Config-if-Vlan1)#ipv6 pim state-refresh origination-interval 90
Switch (Config-if-Vlan1)#
18.1.4 PIM-DM Typical Application
As shown in the following figure, add the Ethernet interfaces of Switch A and Switch
B to corresponding vlan, and start PIM-DM Protocol on each vlan interface.

The configuration procedure for SwitchA and SwitchB is as below:
(1) Configure SwitchA:
Switch (Config) # ipv6 pim multicast-routing
SwitchA
SwitchB
