interval of the LSP packet over p2p links
By default, the LSP packet is transmitted every 5 seconds over the p2p link.
5.2.10 Setting the Hello failure interval
The IS-IS protocol maintains the adjacency among routers by transmitting/receiving the
Hello packets. If the local router does not receive Hello packets in a time interval
transmitted by the peer continuously, it considers the adjacent router as down.
Perform the following configurations in Interface view.

on the interface
By default, the Hello failure interval is 30 seconds. If the level is not specified, it defaults
to setting the Hello packet failure interval of Level-1.
5.2.11 Setting Priority for DIS Election
In the broadcast network, the IS-IS needs to elect a DIS from all the routers.
When you need to select a DIS from the IS-IS neighbors on the broadcast network, you
should select level-1 DIS and level-2 DIS respectively. The higher the priority is, the
more possible it is selected. If there are two or more routers with the highest priority in
the broadcast network, the one with the greatest MAC address will be selected. If all the
adjacent routers' priorities are 0, the one with the greatest MAC address will be
selected.
The DISs of Level-1 and Level-2 are elected separately. You can set different priorities
for DIS election at different levels.
Perform the following configurations in Interface view.
