configure isis hello-multiplier
This command sets the hello multiplier for one or all IS-IS VLANs.
|vlan all||Applies the configuration to all IS-IS VLANs.|
|vlan_name||Specifies a single VLAN to which the configuration applies.|
|multiplier||Sets the hello multiplier. The range is 2 to 100.|
|level [1 | 2]||Limits the configuration to either level 1 or level 2. If neither level 1 nor level 2 is specified, the configuration applies to both levels.|
The hello multiplier is used in conjunction with the hello interval to compute the holding time. The holding time is included in hello PDUs and is calculated by multiplying the hello multiplier by the hello interval. If the hello interval is set to minimal, the holding time is set to 1 second and the hello interval is calculated by dividing 1 second by the hello multiplier. For example, a hello interval of minimal and a hello multiplier of 4 means that the hold interval is set to 250 ms (and the holding time to 1 second). The holding time tells the neighboring router how long to wait before declaring the sending router dead.
The following command sets the SJvlan hello multiplier to 4:
configure isis SJvlan hello-multiplier 4
