Setting the Priority of OSPF

Setting the Priority of OSPF

Context

Routing protocols may share and select routing information because the router may run multiple dynamic routing protocols at the same time. The system sets a priority for each routing protocol. When multiple routing protocols are used to select routes, the route selected by the routing protocol with a higher priority takes effect.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run ospf [ process-id ]

    The OSPF process view is displayed.

  3. Run preference [ ase ] { preference | route-policy route-policy-name } *

    The priority of OSPF is set.

    • If the parameter ase is specified, it indicates that the preference of AS external routes is set.
    • The parameter preference specifies the preference of OSPF routes. The smaller the value, the higher the preference.
    • If the parameter route-policy route-policy-name is specified, it indicates that the preference is set for specified routes according to the routing policy.

    By default, the preference of OSPF routes is 10. When the parameter ase is specified, the default preference of AS external routes is 150.
