Chapter 13 Routing Protocols

•The packet’s message-digest is the same as the one the ZyWALL calculates using the MD5 password.

For RIP, authentication is not available in RIP version 1. In RIP version 2, you can only select one authentication type for all interfaces. For OSPF, the ZyWALL supports a default authentication type by area. If you want to use this default in an interface or virtual link, you set the associated Authentication Type field to Same as Area. As a result, you only have to update the authentication information for the area to update the authentication type used by these interfaces and virtual links. Alternatively, you can override the default in any interface or virtual link by selecting a specific authentication method. Please see the respective interface sections for more information.
