Configuring the Interval for Sending Hello Packets
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
3. Run:
isis timer hello hello-interval [ level-1 | level-2 ]
The interval for sending the Hello packets is set on an interface.
On a broadcast link, there are Level-1 and Level-2 Hello packets. For different types
of packets, you can set different intervals. If no level is specified, both the Level-1
timer and Level-2 timer are configured. On a P2P link, there is only one type of Hello
packets. Therefore, neither level-1 nor level-2 is required.
NOTE
Parameters level-1 and level-2 are configured only on a broadcast interface.
Configuring the Invalid Number of Hello Packets
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
3. Run:
isis timer holding-multiplier number [ level-1 | level-2 ]
The invalid number of Hello packets is set.
If no level is specified, both the Level-1 timer and Level-2 timer are configured.
NOTE
level-1 and level-2 can be found only on the broadcast interface.
IS-IS maintains neighbor relationships with neighbors through Hello packets. If the local
router does not receive any Hello packet from a neighbor within holding time, the local
router declares that the neighbor is invalid.
In IS-IS, the period during which the local router and its neighbor keep the neighbor
relationship is determined by the invalid number of Hello packets and the interval for
sending Hello packets.
