Information About OSPFv3 Demand Circuit Ignore

Demand Circuit Ignore Support

Demand Circuit Ignore Support enables you to prevent an interface from accepting demand-circuit requests from other devices by specifying the ignore keyword in the ipv6 ospf demand-circuit command. Demand circuit ignore instructs the router not to accept Demand Circuit (DC) negotiation and is a useful configuration option on the point-to-multipoint interface of the Hub router.

How to Configure OSPFv3 Demand Circuit Ignore

Configuring Demand Circuit Ignore Support for OSPFv3

SUMMARY STEPS

    1.    enable

    2.    configure terminal

    3.    interface type number

    4.    Enter one of the following commands:

    • ipv6 ospf demand-circuit ignore
    • ospfv3 demand-circuit ignore

    5.    end

    6.    show ospfv3 process-id area-id address-family [vrf {vrf-name |* }] interface [type number] [brief]


DETAILED STEPS
     Command or ActionPurpose
    Step 1 enable


    Example:
    Device> enable
     

    Enables privileged EXEC mode.

    • Enter your password if prompted.
     
    Step 2 configure terminal


    Example:
    Device# configure terminal
     

    Enters global configuration mode.

     
    Step 3 interface type number


    Example:
    Device(config)# interface GigabitEthernet 0/1/0
     

    Configures an interface type and number and enters interface configuration mode.

     
    Step 4Enter one of the following commands:
    • ipv6 ospf demand-circuit ignore
    • ospfv3 demand-circuit ignore


    Example:
    Device(config-if)# ipv6 ospf demand-circuit ignore


    Example:
    Device(config-if)# ospfv3 demand-circuit ignore
     

    Prevents an interface from accepting demand-circuit requests from other devices.

     
    Step 5 end


    Example:
    Device(config-if)# end
     

    Returns to privileged EXEC mode.

     
    Step 6 show ospfv3 process-id area-id address-family [vrf {vrf-name |* }] interface [type number] [brief]


    Example:
    Device# show ospfv3 interface GigabitEthernet 0/1/0
     

    (Optional) Displays OSPFv3-related interface information.
