Description
Use the
isis timer holding-multiplier
command to specify the IS-IS hello multiplier.
Use the
undo isis timer holding-multiplier
command to restore the default.
The default IS-IS hello multiplier is 3.
If no level is specified, the hello multiplier applies to the current level.
With the IS-IS hello multiplier configured, a router can uses hello packets to notify its neighbor router
of the adjacency hold time (hello multiplier times hello interval). If the neighbor router receives no hello
packets from this router within the hold time, it declares the adjacency down. You can adjust the
adjacency hold time by changing the hello multiplier or the hello interval on an interface.
Level-1 and Level-2 hello packets are sent independently on a broadcast network, so you need to
specify a hello multiplier for the two levels respectively. On a P2P link, Level-1 and Level-2 packets are
both sent in P2P hello packets, and you need not specify Level-1 or Level-2.

Examples
# Configure the number of Level-2 Hello intervals as 6 for interface VLAN-interface, that is, if no Hello
packet is received from the interface within 6 hello intervals, the IS-IS neighbor is considered dead.

Parameters
time
: Specifies the minimum interval in milliseconds for sending link-state packets, ranging from 1 to

Use the
isis timer lsp
command to configure the minimum interval for sending LSPs on the interface
and specify the maximum LSPs that can be sent per time.
Use the
