## 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
