Configuring a stub area

OSPFv3 areas can be defined as stub areas with modifiable parameters.

1. Enter the configure terminal command to access global configuration mode.
   

   device# configure terminal

2. Enter the ip router-id command to specify the router ID.
   

   device(config) ip router-id 10.4.4.4

3. Enter the ipv6 router ospf command to enter OSPFv3 router configuration mode and enable OSPFv3 on the device.
   

   device(config)# ipv6 router ospf

4. Enter the area stub command and specify a metric value.
   

   device(config-ipv6-router-ospf-vrf-default-vrf)# area 4 stub 100

   Area 4 is defined as a stub area with an additional cost of 100.

Example

The following example sets an additional cost of 100 on a stub area defined as 4.

device# configure terminal
device(config)# ip router-id 10.4.4.4 
device(config)# ipv6 router ospf 
device(config-ipv6-router-ospf-vrf-default-vrf)# area 4 stub 100
