Configuring OSPF virtual link settings

The OSPF interface parameters for this process are automatically set to their default values for virtual links. You can optionally adjust the following OSPF virtual link settings.

Prerequisites

You must be in the router vlink configuration context, as indicated by the switch(config-router-vlink)# prompt.

Procedure
  • Set the time interval between OSPF hello packets for the OSPF virtual links using the following command. For command details, see hello-interval.

    hello-interval <seconds>

    For example:
    switch(config)# router ospf 1
    switch(config-router)# area 100 virtual-link 100.0.1.1
    switch(config-router-vlink)# hello-interval 30
  • Set the interval after which a neighbor is declared dead if no hello packet is received on the OSPF virtual links. Use the following command. For command details, see dead-interval.

    dead-interval <seconds>

  • Set the time between retransmitting lost link state advertisements for the OSPF virtual links using the following command. For command details, see retransmit-interval.

    retransmit-interval <seconds>

  • Sets the transit delay in Link state transmission for the OSPF virtual links using the following command. For command details, see transit-delay
