Command Usage
• The hello-holdtime indicates how many seconds the router holds an
entry for a neighbor that has stopped sending hello messages.
• The hello-holdtime should be included in each hello message received
from a neighbor. Routers on the same subnet may therefore have
different hello-holdtimes.
• If the hello interval is set at the default value of 30 seconds, then the
default hello-holdtime is 105 seconds. If the hello-holdtime has not been
configured, then every time the hello interval is updated (see section
7.27.41 on page 1157), the hello-holdtime is automatically updated.
However, if the hello-holdtime has been configured, then it will not be
updated when the hello interval changes. Also, note that if a value is set
for the hello-holdtime that is less than the hello interval, the command
will fail.
• When the
no ip pim hello-holdtime
is entered, the hello-holdtime
is set to 3.5 times the current hello interval.
Example
This example sets the hello-holdtime on VLAN 1.
