BLADEOS 6.5.2 Application Guide

Example 3: Summarizing Routes

By default, ABRs advertise all the network addresses from one area into another area. Route summarization can be used for consolidating advertised addresses and reducing the perceived complexity of the network.

If network IP addresses in an area are assigned to a contiguous subnet range, you can configure the ABR to advertise a single summary route that includes all individual IP addresses within the area.

The following example shows one summary route from area 1 (stub area) injected into area 0 (the backbone). The summary route consists of all IP addresses from 36.128.192.0 through 36.128.254.255 except for the routes in the range 36.128.200.0 through 36.128.200.255.

Note – OSPFv2 supports IPv4 only. IPv6 is supported in OSPFv3 (see “OSPFv3 Implementation in BLADEOS” on page 298).

Figure 36 Summarizing Routes

Note – You can specify a range of addresses to prevent advertising by using the hide option. In this example, routes in the range 36.128.200.0 through 36.128.200.255 are kept private.

Use the following procedure to configure OSPF support as shown in Figure 36:

1.Configure IP interfaces for each network which will be attached to OSPF areas.

RS G8124(config)# interface ip 1

RS G8124(config-ip-if)# ip address 10.10.7.1

RS G8124(config-ip-if)# ip netmask 255.255.255.0

RS G8124(config-ip-if)# enable

RS G8124(config-ip-if)# exit

RS G8124(config)# interface ip 2

RS G8124(config-ip-if)# ip address 36.128.192.1

RS G8124(config-ip-if)# ip netmask 255.255.255.0

RS G8124(config-ip-if)# enable

RS G8124(config-ip-if)# exit
