v Demo: RIP routing Induction with default route announcements

Demo Target: Configuration RIP the route is summarized with the default route.

Demo Environment: as shown in 6.50.

Demo Background:Here you can put the routerBackboneas a backbone router on the network, the routerR1as an enterprise border router configured on the router4Subnets :172.16.1.1/24,172.16.2.1/24,172.16.3.1/24,172.16.4.1/24. If the backbone routerBackboneuse with Enterprise border routersRIPDynamic routing protocols to announce and learn from each other, then the backbone routersBackbonewill exist on the routerR1on4the specific routing entry for the subnet. In this instance, an enterprise border router bulletin4Specific routing entries, if any -Enterprise Border routers, each with4subnet, it will exist on the backbone router -Route entry. If the network is planning this, the routing entries for the backbone routers will become very large, which will affect the route selection performance, so at the enterprise boundaryRIPit is necessary to perform a routing generalization on the router. AlthoughRIPprovides automatic summarization of routes (auto-summary) feature, but this feature onlyVLSMsubnets are automatically aggregated into a standard main class network, such as:172.16.1.1/24,172.16.2.1/24,172.16.3.1/24,172.16.4.1/24automatically aggregated into172.16.0.0/16the form, if you want to summarize it according to the actual situation172.16.1.0/21in the form of bits, the auto-summarize feature will not meet the requirements at this time, need to takeRIPManual summary of the way to meet non-standard class routing induction.

     corresponding6.50The experimental environment shown for the backbone routersBackboneand the Enterprise Border router configuration interfaceIPaddress, and startRIPDynamic routing protocol. The specific configuration is as follows.

Routers Backbone the configuration:

Backbone (config) #inte e1/0

Backbone (config-if) #ip address 192.168.2.2 255.255.255.0

Backbone (CONFIG-IF) #no shutdown

Backbone (config) #router rip

Backbone (config-router) #no auto-summary

Backbone (Config-router) #version 2

Backbone (config-router) #network 192.168.2.0

Routers R1 the configuration:

R1 (config) #interface loopback 1

R1 (config-if) #ip address 172.16.1.1 255.255.255.0

R1 (config) #interface loopback 2

R1 (config-if) #ip address 172.16.2.1 255.255.255.0

R1 (config) #interface Loopback 3

R1 (config-if) #ip address 172.16.3.1 255.255.255.0

R1 (config) #interface Loopback 4

R1 (config-if) #ip address 172.16.4.1 255.255.255.0

R1 (config) #interface e1/0

R1 (config-if) #ip address 192.168.2.1 255.255.255.0

R1 (config-if) #no shutdown

R1 (config) #router rip

R1 (config-router) #no auto-summary

R1 (config-router) #version 2

R1 (config-router) #network 172.16.0.0

R1 (config-router) #network 192.168.2.0

when the above configuration is complete, the trunk router can be Backbone on the pass command show ip Route Check to see the trunk router . Backbone The routing table
