Chapter 11 Routing Protocols its routes asynchronously to the network and converges slowly. Therefore, RIP is more suitable for small networks (up to 15 routers). • In the UAG, you can configure two sets of RIP settings before you can use it in an interface. • First, the Authentication field specifies how to verify that the routing information that is received is the same routing information that is sent. This is discussed in more detail in Authentication Types on page 175. • Second, the UAG can also redistribute routing information from non-RIP networks, specifically OSPF networks and static routes, to the RIP network. Costs might be calculated differently, however, so you use the Metric field to specify the cost in RIP terms. • RIP uses UDP port 520. Use the RIP screen to specify the authentication method and maintain the policies for redistribution. Click Configuration > Network > Routing > RIP to open the following screen. Figure 105 Configuration > Network > Routing > RIP The following table describes the labels in this screen. Table 66 Configuration > Network > Routing Protocol > RIP LABEL Authentication Authentication DESCRIPTION Select the authentication method used in the RIP network. This authentication protects the integrity, but not the confidentiality, of routing updates. None uses no authentication. Text uses a plain text password that is sent over the network (not very secure). Text Authentication Key MD5 Authentication ID MD5 uses an MD5 password and authentication ID (most secure). This field is available if the Authentication is Text. Type the password for text authentication. The key can consist of alphanumeric characters and the underscore, and it can be up to 16 characters long. This field is available if the Authentication is MD5. Type the ID for MD5 authentication. The ID can be between 1 and 255. 166 UAG715 User's Guide
