Configuring An Asbr - HP ProCurve Secure Router 7203 dl Advanced Management And Configuration Manual

IP Routing—Configuring RIP, OSPF, BGP, and PBR
Quick Start
13-180
6. If the ABR will be sending summary LSAs, define the address ranges for
these summaries. Select which routes the ABR should advertise and
which it should not.
Syntax: area <area ID> range <network A.B.C.D> <subnet mask> [advertise | not-
advertise]
If you do not select an option for advertising, the router will automatically
advertise the summary. For example:
ProCurve(config-ospf)# area 0 range 10.1.0.0 255.255.0.0
ProCurve(config-ospf)# area 1 range 10.2.0.0 255.255.0.0
ProCurve(config-ospf)# area 2 range 10.3.0.0 255.255.0.0 not-advertise
7. Specify the stub areas, which receive a default route and summary routes
for inter-area traffic.
Syntax: area <area ID> stub
8. Specify the total stub areas, which receive only a default route.
Syntax: area <area ID> stub no-summary

Configuring an ASBR

1. If one does not already exist, create a loopback interface.
Syntax: interface loopback <interface number>
2. Assign the loopback interface an IP address.
Syntax: ip address <A.B.C.D> <subnet mask>
This address should be the local router ID. For example:
ProCurve(config-loopback 1)# ip address 192.168.255.4 /28
Syntax: ip address <router ID> <subnet mask>
3. Enable the external routing protocol. (See, for example, the Quick Start
for BGP or RIP.)
4. Access the OSPF configuration mode context.
ProCurve(config)# router ospf
5. Enable OSPF on the interface that connects to other routers in the internal
network.
Syntax: network <network A.B.C.D> <wildcard bits> area <area ID>
For example:
ProCurve(config-ospf)# network 10.1.2.0 0.0.0.255 area 0
