Configuring OSPFv3 parameters

Use the following syntax to configure OSPF3 parameters.

config>router# ospf3
        asbr
        export policy-name [policy-name...(up to 5 max)]
        external-db-overflow limit seconds
        external-preference preference
        overload [timeout seconds]
        overload-include-stub
        overload-on-boot [timeout seconds]
        preference preference
        reference-bandwidth bandwidth-in-kbps
        router-id ip-address
        no shutdown
        timers
            lsa-arrival lsa-arrival-time
            lsa-generate max-lsa-wait [lsa-initial-wait lsa-initial-wait [lsa-second-wait lsa-second-wait]]
            spf-wait max-spf-wait [spf-initial-wait spf-initial-wait [spf-second-wait spf-second-wait]]

Example: OSPF3 configuration output

A:SAS-12>config>router>ospf3# info
----------------------------------------------
            asbr
            overload
            timers
                lsa-arrival 50000
            exit
            export "OSPF-Export"
----------------------------------------------
A:SAS-12>config>router>ospf3#

OSPF also supports the concept of multi-instance OSPFv2 and OSPFv3 which allows separate instances of the OSPF protocols to run independently within SRĀ OSs.

Separate instances are created by adding a different instance ID as the optional parameter to the config>router>ospf and config>router>ospf3 commands. When this is done a separate OSPF instance is created which maintains separate link state databases for each instance.
