Specifies the OSPF router ID. This ID must be established in every OSPF instance. If not explicitly configured, the highest logical IP address is duplicated as the router identifier. However, since the router identifier is not an IP address, it does not have to be a part of any routable subnet in the network.

Supported in the following platforms:

  • Access Points — AP 7161, AP 7502, AP-7522, AP 7532, AP 7562, AP 7602, AP 7622, AP-8163, AP-8432, AP-8533
  • Wireless Controllers — RFS 4000
