Parameter
Description
area-id
ID of the area in which the addresses are converged.
It can be an integer or an IPv4 prefix.
ipv6-prefix/prefix-length
Range of the converged addresses.
advertise
Advertises the range of converged addresses.
not-advertise
The range of the converged addresses is not advertised.
By default, the function is enabled.
Defaults
No converged inter-area address range is defined by default.

Usage Guide
This command applies only to ABR. Use this command to converge multiple routes of an area into
one route and advertise it to other areas. This command applies only to ABR. Use this command to
converge multiple routes of an area into one route and advertise it to other areas. The routing
information combination only takes place on the area border. The specific routing information is seen
on the intra-area routers, but only one converged route can be seen on the devices in other areas. By
configuring the two options of advertise and not-advertise, you can decide whether to advertise the
convergence range to enable blocking and filtering. By default, the range is advertised to the outside.
The option cost can be used to set the metric value of convergence routing.
A number of route convergence commands can be defined. In this way, the number of the routes in
the OSPF AS is reduced. Particularly for a large network, the forwarding performance will be
improved.
When a number of routes are converged, and the containment relationship exists between items, the
area range converged is determined by the longest match principle.
Configuration
Examples
The following example converges the routes in area 1.
ipv6 router ospf 1
area 1 range 2001:abcd:1:2::/64
