Configuring default external routes

OSPFv3 default routes can be created and advertised.
  1. Enter the configure terminal command to access global configuration mode. 
    device# configure terminal
  2. Enter the ipv6 router ospf command to enter OSPFv3 router configuration mode and enable OSPFv3 globally. 
    device(config)# ipv6 router ospf
  3. Enter the default-information-originate command with the always, metric, and metric-type parameters. 
    device(config-ospf6-router)# default-information-originate always metric 2 metric-type type1
    A default type 1 external route with a metric of 2 is created and advertised.

The following example creates and advertises a default route with a metric of 2 and a type 1 external route. 

device# configure terminal
device(config)# ipv6 router ospf 
device(config-ospf6-router)# default-information-originate always metric 2 metric-type type1
