Networking Routing 2 • Metric: Enter a number from 2 to 15 to manage the priority of the route. If multiple routes to the same destination exist, the route with the lowest metric is chosen. STEP 4 Click Apply to save your settings. Dynamic Routing Dynamic Routing or RIP, is an Interior Gateway Protocol (IGP) that is commonly used in internal networks. It allows a router to exchange its routing information automatically with other routers, and allows it to dynamically adjust its routing tables and adapt to changes in the network. NOTE RIP is disabled by default. STEP 1 Click Networking > Routing > Dynamic. The Dynamic Routing (RIP) window opens. STEP 2 In the RIP Configuration area, enter the following information: • RIP Direction: Determines how the router sends and receives RIP packets: - Both: The router both broadcasts its routing table and also processes RIP information received from other routers. - Out Only: The router broadcasts its routing table periodically but does not accept RIP information from other routers. - In Only: The router accepts RIP information from other routers, but does not broadcast its routing table. - None: The router neither broadcasts its route table nor does it accept any RIP packets from other routers. This effectively disables RIP. • RIP Version: Choose one of the following options: - Disabled: If RIP is disabled, this is selected. - RIP-1 is a class-based routing version that does not include subnet information. This is the most commonly supported version. - RIP-2 includes all the functionality of RIPv1 plus it supports subnet information. Though the data is sent in RIP-2 format for both RIP-2B and RIP-2M, the mode in which packets are sent is different. Cisco SA500 Series Security Appliances Administration Guide 69
