OSPF Configuration
Commands
This section describes the commands you can use to configure the Open Shortest
Path First (OSPF) routing protocol.
When the Switch 7700 runs a routing protocol, it is able to perform the functions
of a router. The term router in this section can refer either to a physical router or to
the Switch 7700 running a routing protocol.
abr-summary Syntax
abr-summary ip_address ip_mask [ advertise | not-advertise ]
undo abr-summary ip_address ip_mask
View
OSPF Area view
Parameter
ip_address Enter a network segment IP address.
ip_mask Enter the subnet mask.
Description
Using the abr-summary command, you can configure the route aggregation on
the area border router.
Using the undo abr-summary command, you can disable the route aggregation on
the area border router. This is the default.
This command is applicable only to the area border router (ABR) and is used for
the route aggregation in an area. The ABR only transmits an aggregated route to
other areas. Route aggregation refers to that the routing information is processed
in the ABR and for each network segment configured with route aggregation,
there is only one route transmitted to other areas.
Example
To enter area 1, and then aggregate the network segments, 66.48.10.0 and
66.48.120.0 into the summary route 66.48.0.0, enter the following:
[SW7700-ospf]area 1
[SW7700-ospf-area-0.0.0.1]network 66.48.10.0 0.0.0.255
[SW7700-ospf-area-0.0.0.1]network 66.48.120.0 0.0.0.255
[SW7700-ospf-area-0.0.0.1]abr-summary 66.48.0.0 255.255.0.0
