5.2.5.1 Configuring Inter-area Route
Aggregation
The ABR in an area needs to advertise the routes in the area to other areas. If the
route addresses are continuous, the ABR aggregates these routes and then
advertises it.
To configure inter-area route aggregation, execute the following command in the
OSPFv3 configuration mode:
Command Function
area area-id range
ipv6-prefix/prefix-length [advertise |
not-advertise]
Configure inter-area route aggregation.
area-id: Set the aggregated area id.
ipv6-prefix/prefixlength: Set the ipv6 prefix of
the aggregated route.
advertise|not-advertise: Advertise or not
advertise the aggregated summary-LSA.
Use the no area area-id range {ipv6-prefix /prefix-length} command to disable the
inter-area route aggregation.
5.2.5.2 Configuring Outer-area Route
Aggregation
The route aggregation is allowed to take place when redistributing the generated
Type-5 LSA on the ASBR.
To configure outer-area route aggregation, execute the following command in the
OSPFv3 configuration mode:
Command Function
summary-prefix ipv6-prefix /
prefix-length [not-advertise | tag
tag-value]
Configure outer-area route aggregation.
ipv6-prefix/prefixlength: Set the ipv6
prefix of the aggregated route.
not-advertise: Not advertise the
aggregated LSA.
tag-value: The valid range is
<0-4294967295>, used to specify the tag
value for the aggregated LSA.
Use the no summary-prefix ipv6-prefix/prefix-length command to disable the
outer-area route aggregation.
