Disable an Internal Address Range

This example disables an internal range that is not to be advertised.

1. Ensure that the entire summary for this fec0::1111:0:0 address range is not advertised.

   SEFOS(config-router)# area 0.0.0.6 range fec0::1111:0:0 96 not-advertise summary
   

2. In SEFOS1, check whether the inter area prefix LSA advertised by 10.0.0.1 is missing.

   SEFOS# show ipv6 ospf area 0.0.0.0 database detail
