Quidway S6500 Series Ethernet Switches
The value parameter is configured according to the link state of the Interface.
By default, the routing cost of IS-IS on Interface is 10.
5.2.6 Setting the Hello Packet Broadcast Interval
The IS-IS periodically sends the Hello packets from the Interface and the routers
maintain the adjacency through the transmitting/receiving of the Hello packets The
Hello packet interval can be modified.
Usually, on the broadcast links, there exist level-1 and level-2 hello packets. For
different packets, different broadcast intervals should be set. However, there are two
exceptions. One is when there is no level separation in the link, parameters of level-1
and level-2 need not be specified in the command (adopt the default values). So that
the system will set the broadcast intervals of all packets as that of the level-1 hello
packet. The other is if hello packets are not separated according to level-1 and level-2
on the p2p links, the attribute of the packets need not be set either.
Perform the following configurations in Interface view.
Table 5-6 Setting the Hello packet broadcast interval
Set Hello packet interval, measured in
seconds.
Restore the default Hello packet interval on
the interface
By default, Hello packets are transmitted on Interface every 10 seconds.
5.2.7 Setting the CSNP Packet Broadcast Interval
The CSNP packet is transmitted by the DIS over the broadcast network to synchronize
the link state database (LSDB). The CSNP packet is regularly broadcast over the
broadcast network at an interval, which can be set by users.
Perform the following configurations in Interface view.
