configured or hello_holdtime is configured but less than current hello_interval, hello_holdtime is
modified to 3.5*hello_interval, otherwise the configured value is maintained. The command can
configure on IPv6 tunnel interface, but it is successful configuration to only configure tunnel
carefully.
Example:
Configure vlan1’s Hello Holdtime to 10s
Switch (config)# interface vlan1
Switch (Config -if-Vlan1)#ipv6 pim hello-holdtime 10
45.3.19 ipv6 pim hello-interval
Command:
ipv6 pim hello-interval <interval>
no ipv6 pim hello-interval
Function:
Configure the interface’s hello_interval of pim hello packets. The “no ipv6 pim hello-interval”
command restores the default value.
Parameter:
<interval> is the hello_interval of periodically transmitted pim hello packets’, ranges from 1 to
18724s
Default:
The default periodically transmitted pim hello packets’ hello_interval is 30s.
Command Mode:
Interface Configuration Mode
Usage Guide:
Hello messages make pim switches oriented each other and determine neighbor relationship. Pim
switch announce the existence of itself by periodically transmitting hello messages to neighbors. If
no hello messages from neighbors are received in the certain time, the neighbor is considered lost.
This value can’t be greater than neighbor overtime. The command can configure on IPv6 tunnel
interface, but it is successful configuration to only configure tunnel carefully.
Example:
Configure VLAN’s pim-sm hello_interval.
Switch (config)#interface vlan 1
Switch(Config-if-Vlan1)#ipv6 pim hello-interval 20
