Dynamic RoutingDynamic RoutingA routing protocol is the language a router speaks with other routers to share information about the statusof network routing tables. With static routing, routing tables are set and do not change. If a router onthe remote path fails, a packet cannot get to its destination.Dynamic routing lets routing tables in routers change as the routes change. If the best path to a destinationcannot be used, dynamic routing protocols change routing tables when necessary to keep yournetwork traffic moving. Fireware® Pro supports RIP v1 and v2, OSPF, and BGP v4 dynamic routing protocols.Fireware supports only RIP v1 and v2.Routing daemon configuration filesTo use any of the dynamic routing protocols with Fireware, you must import or type a dynamic routingconfiguration file for the routing daemon you choose. This configuration file includes information suchas a password and log file name. You can find configuration templates for each of the routing protocolsin this FAQ:https://www.watchguard.com/support/advancedfaqs/fw_dynroute-ex.aspYou can find a list of supported configuration commands for each routing protocol in the sectionsbelow. The command sections below appear in the order they must go in an operating configurationfile.Notes about configuration files:• The “!” and the “#” characters are comment characters. If the first character of the word is one ofthe comment characters, then the rest of the line is interpreted as a comment. If the commentcharacter is not the first character of the word, it is interpreted as a command.• Usually, you can use the word “no” at the beginning of the line to disable a command. Forexample: “no network 10.0.0.0/24 area 0.0.0.0” disables the backbone area on the specifiednetwork.Using RIPNoteSupport for this protocol is available in both Fireware® and Fireware Pro.RIP (Routing Information Protocol) is used to manage router information in a self-contained network,such as a corporate LAN or a private WAN. With RIP, a gateway host sends its routing table to the closestrouter each 30 seconds. This router, in turn, sends the contents of its routing tables to neighboring routers.RIP is best for small networks. This is because the transmission of the full routing table each 30 secondscan put a large traffic load on the network, and because RIP tables are limited to 15 hops. OSPF is a betteralternative for larger networks.RIP Version 1RIP V1 uses a UDP broadcast over port 520 to send updates to routing tables. To create or modify a routingconfiguration file, here is a table of supported routing commands. The sections must appear in theconfiguration file in the same order they appear in this table. You can also use the sample RIP configurationfile found in this FAQ:https://www.watchguard.com/support/advancedfaqs/fw_dynroute-ex.asp326 WatchGuard System Manager
