Router ID

Routing devices in OSPF areas are identified by a router ID. The router ID is expressed in IP address format. The IP address of the router ID is not required to be included in any IP inter- face range or in any OSPF area.

The router ID can be configured in one of the following two ways:

„Dynamically—OSPF protocol configures the lowest IP interface IP address as the router ID. This is the default.

„Statically—Use the following command to manually configure the router ID:

>># /cfg/l3/rtrid <IP address>

„To modify the router ID from static to dynamic, set the router ID to 0.0.0.0, save the con- figuration, and reboot the GbE Switch Module. To view the router ID, enter:

>># /info/l3/ospf/gen

Authentication

OSPF protocol exchanges can be authenticated so that only trusted routing devices can partici- pate. This ensures less processing on routing devices that are not listening to OSPF packets.

OSPF allows packet authentication and uses IP multicast when sending and receiving packets. Routers participate in routing domains based on predefined passwords. Alteon OS supports simple password (type 1 plain text passwords) and MD5 cryptographic authentication. This type of authentication allows a password to be configured per area.
