Important Considerations

The system uses the specified advertisement address to advertise routes to other stations on the same network. It uses this address for sending updates. (RIP-2 updates depend on the setting of RIP compatibility mode.)

Advertisement addresses are handled differently based on RIP-1 and RIP-2.

For the CoreBuilder 3500, each interface that you define initially uses the default broadcast address (255.255.255.255) as the advertisement address. With RIP-1 updates, the address that you specify becomes the new RIP-1 advertisement address if you change the broadcast address. If you subsequently use RIP-2 (configure the interface to send RIP-2 advertisements) and have the RIP-1 compatibility mode disabled, the multicast address is used for updates.

For the CoreBuilder 9000, each interface that you define initially uses the directed broadcast address as the RIP advertisement address (all 1s in the host field).

You can specify up to 64 advertisement addresses in separate iterations.

On the CoreBuilder 3500:

After you add an advertisement address, you cannot subsequently change the broadcast address.

If you are using RIP-2 for the interface, you must enable RIP compatibility mode if you want the system to use the advertisement list instead of the multicast address for RIP updates. See “ip rip compatibilityMode” earlier in this chapter for more information.

To add an advertisement address on other platforms, you must remove the directed broadcast address if you only want the address that you added to be used for RIP advertisements.
