OSPF link detection customization

OSPF link detection customization

OSPF route detection and interface-down detection can be customized by customizing the Link State Advertisement (LSA) refresh intervals and enabling fast-link failover using the config router ospf command:

config router ospf
    set lsa-refresh-interval <integer>
    config ospf-interface
        edit <name>
            set interface <string>
            set linkdown-fast-failover {enable | disable}
        next
    end
end

set lsa-refresh-interval <integer>

How often LSA refreshes for OSPF, in seconds (0 to 5, default = 5).

set linkdown-fast-failover {enable | disable}

Enable/disable fast link failover.

  • enable: OSPF updates the link status from up to down and advertises the LSA update as soon as the underlying physical interface goes down.

  • disable: Disable the use of OSPF and use the kernal detection and notification instead.

Used when the ospf-interface interface attribute is configured, and the type of the underlying interface is VLAN.
