Configure the Default Summary Route Cost for a Stub Area

If default summary routes are selected, you can configure the cost for the default summary route that is sent to a stub area.

1. Enter Global Configuration mode in SEFOS1.

   SEFOS# configure terminal
   

2. Enable OSPF globally in SEFOS1.

   SEFOS(config)# ipv6 router ospf
   

3. Configure the OSPF router ID.

   SEFOS(config-router)# router-id 10.0.0.1
   

4. Configure the area 0.0.0.6 as a stub area.

   SEFOS(config-router)# area 0.0.0.6 stub
   

5. Configure the cost as 20.

   SEFOS(config-router)# area 0.0.0.6 default-metric 20
   SEFOS(config-router)# end
   

6. Ensure that the correct cost is set.

   SEFOS# show ipv6 ospf areas
