adjust hello interval

Syntax

area [area-id] virtual link [router-id] hellointerval [1 - 65535]

Description

In the ospf3 context, used on both ABRs in a virtual link to indicate the length of time between the transmission of hello packets between the ABRs on opposite ends of the virtual link. The hello-interval setting must be the same on both ABRs on a given virtual link.

Options

area-id

Specifies the OSPFv3 area in which both ABRs in a given virtual link operate. In this use, the area ID is sometimes termed "transit area ID". This value must be the same for both ABRs in the virtual link. If the area does not exist, this command creates it.

router-id

For an ABR in a given virtual link, this is the router ID (in decimal or 32-bit dotted decimal format) used to create the link on that ABR.

The no version restores the default value.

Default: 10 seconds

Example input

To change the hello-interval on the virtual link configured for the network in Figure 25: Defining OSPFv3 virtual links within a network to 60 seconds:

  • On routing switch “A” (router ID 10.0.0.1) you would use the following command to reconfigure the current hello-interval to 60 seconds: Switch(ospf3)# area 1 virtual-link 209.157.22.1 hellointerval 60

  • On routing switch “C” (router ID 209.157.22.1) you would use the following command to reconfigure the current hello-interval to 60 secondsSwitch(ospf3)# area 1 virtual-link 10.0.0.1 hello-interval 60
