Usage guidelines 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 does not receive any 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 each level. 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. You can configure keywords level-1 and level-2 only on broadcast interfaces. Before doing that, enable IS-IS on the interface. If no level is specified, the hello multiplier applies to the current level. The value of hello multiplier multiplied by hello interval cannot be more than 65535. Examples # Configure the hello multiplier as 6 for VLAN-interface 10. system-view [Sysname] interface vlan-interface 10 [Sysname-Vlan-interface10] isis timer holding-multiplier 6 Related commands isis timer hello isis timer lsp Use isis timer lsp to configure the minimum interval for sending LSPs on the interface and specify the maximum number of LSPs that can be sent per time. Use undo isis timer lsp to restore the default. Syntax isis timer lsp time [ count count ] undo isis timer lsp Default The minimum interval for sending LSPs on the interface is 33 milliseconds, and the maximum number of LSPs that can be sent at a time is 5. Views Interface view Predefined user roles network-admin Parameters time: Specifies the minimum interval in milliseconds for sending link-state packets, in the range of 1 to 1000. count: Specifies the maximum number of link-state packets to be sent at one time, in the range of 1 to 1000. 179
