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-ipv6-router-ospf-vrf-default-vrf)# default-information-originate always metric 2 metric-type type1

   A default type 1 external route with a metric of 2 is created and advertised.
