Characteristics and establishment of r12002 Route Network

The characteristics of RIPv2 routing network and the formation of the RIP routing Protocol (Router Information Protocol) include two versions: r1_1 and r1_2. The RIP Protocol is the earliest distance vector IP address routing selection protocol. The hop count is used as the unique measurement value. Although some later routing protocols are not powerful, they are easy to use and are still widely used in the design of small network data interconnection. R12001 sends route updates without the subnet mask. r12002 carries the subnet mask of each route entry. Route update for r12001 broadcast transmission; broadcast address: 255.255.255.255; r00002 multicast transmission route update; multicast address: 224.0.0.9. Www.2cto.com r00002 route selection update with authentication function. RIPv2 each route update entry carries the next hop address. The update package of r00002 contains an externally marked path. Their main difference: r12001 is a class routing protocol, while r12002 is a class routing protocol. RIPv1 does not support discontinuous subnets, while RIPv2 does. Review the configuration of r12001: first, start the rip process on the vro, and then declare the primary network number of all interfaces that start RIP on the vro, specific configuration command ---- www.2cto.com Router (config) # router ripRouter (config-router) # network-number RIPv2 carries a subnet mask when sending route updates, and supports discontinuous subnets, however, r12002 summarizes routes on the primary network border by default. Therefore, you must disable the routing summary function and allow the subnet to advertise the boundaries of the primary network. Specific configuration: Router (config) # router ripRouter (config-router) # version 2 Router (config-router) # no auto-summary change the three routers to A, B, and CA (config) # int f0/0A (config-if) # ip address 10.1.1.1 255.255.255.255.0A (config-if) # no shutdown A (config) # int f0/1A (config-if) # ip address 192.168.1.1 255.255.255.0A (config-if) # no shutdown B (config) # int f0/0B (config-if) # ip address 10.1.2.1 255.255.255.0B (config-if) # no shutdown www. 2ct O.com B (config) # int f0/1B (config-if) # ip address 192.168.1.2 255.255.255.0B (config-if) # no shutdown C (config) # int f0/0C (config-if) # ip address 192.168.2.1 255.255.0c (config-if) # no shutdown C (config) # int f0/1C (config-if) # ip address 192.168.1.3 255.255.255.0C (config-if) # no shutdown router interface ip address Configuration is complete, then start r12002 on the router, and declare the primary network number: A (config) # router ripA (config-router) # version 2A (config-router) # no auto-summaryA (co Nfig-router) # network 10.1.1.0A (config-router) # network 192.168.1.0 B (config) # router ripB (config-router) # version 2B (config-router) # no auto-summaryB (config-router) # network 10.1.2.0B (config-router) # network 192.168.1.0 C (config) # router ripC (config-router) # version 2C (config-router) # no auto-summaryC (config-router) # network 192.168.2.0C (config-router) # network 192.168.1.0 www.2cto.com After configuring r12002 on the vro, view routing protocols You can see that version 2 is used to receive and send route updates. Related command: A # show ip protocol A # debug ip rip A # show ip route finally, set the appropriate ip address and gateway on the PC, and use the ping command to check the connectivity.
