5.7.8 Configuring Stub area
For the non-backbone area at the edge of Autonomous System (AS), you can configure the
stub command on all routers in the area to configure the area to a Stub area. In this case,
Type5 LSA, which is used to describe external routes of the AS, cannot be flooded in the Stub
area. This facilitates reducing the routing table size.
Configure the Stub area for the ISCOM2600G-HI series switch as below.
Enter global configuration mode.
Raisecom(config)#router
ospf
process-id
[ router-id
router-id
]
Enable an OSPF process and enter OSPF
configuration mode.
Raisecom(config-router-
ospf)#area
area-id
stub
[ no-summary ]
Configure the area to a Stub area.
The no-summary parameter is used to disable
the ABR to send Summary LSA to the Stub
area. It means that it is a Totally Stub area and
the ABR is available for the Stub only.
By default, no area is the Stub area.
Raisecom(config-router-
ospf)#area
area-id
default-cost
cost
Configure the default route cost of the Stub
area.
This command is available for the ABR in the
Stub area only.
By default, it is 1.
Raisecom(config-router-
ospf)#area
area-id
nssa
[ no-summary ]
(Optional) configure the area to NSSA.
All routers in the Stub area must be configured with the Stub property through the
area area-id stub command.
To configure an area to a Totally Stub area, all routers in the area must be
configured by the area area-id stub command. In addition, all ABRs in the area
must be configured by the area area-id stub no-summary command.
The backbone area cannot be configured to the Stub area.
ASBR should not be in the Stub area. It means that routers besides the AS cannot
be transmitted in the Stub area.
5.7.9 Controlling OSPF routing information
