Route-map analysis

Route-map analysis Route-map can control route entries and control routes that are not learned. As shown in: R1 (config) # int e0/0R1 (config-if) # ip add 12.12.1 255.255.0r1 (config-if) # no sh has four loose 1.1.1.12.2.2.23.3.3.34.4.4.4 R2 (config) # int e0/0R2 (config-if) # ip add 12.12.12.2 255.255.255.0R2 (config-if) # no shR2 (config-if) # int e0/1R2 (config-if) # ip add 23.23.23.1 255.255.255.0R2 (config-if) # no sh R3 (config) # int e0/1R3 (config-if) # ip add 23.23.23.2 255.255.255.0R3 (config-if) # no sh and then run ripR1 (config) on r1 )# Router ripR1 (config-router) # no auR1 (config-router) # ver 2R1 (config-router) # net 12.12.0r1 (config-router) # net 1.1.1.0R1 (config-router) # net 2.2.2.0R1 (config-router) # net 3.3.3.0R1 (config-router) # Run ospfR3 (config) # router ospf 111R3 (config-router) on net 4.4.4.0 R3) # net 23.23.23.0 0.0.0.255 area 0 R2 R2 (config) # router ripR2 (config-router) # no auR2 (config-router) # ver 2R2 (config-router) # net 12.12.12.0 R2 (con Fig) # router ospf 111R2 (config-router) # net 23.23.23.0 0.0.0.255 area 0R2 (config-router) # ex then run redistribution r2 (config) on R2) # router ospf 111R2 (config-router) # redistribute rip subnets R2 (config) # router ripR2 (config-router) # redistribute ospf 111 metric 1 the key to our experiment is the control of route entries implemented by route-map. For example, we only want r3 to learn 1.1.1.1 and 2.2.2.2. The steps are as follows: Write aclR2 (config) first) # access-list 1 permit 1.1.1.0 0.0.255r2 (config) # access-list 1 permit 2.2.2.0 0.0.0.255 only allows 1 and 2 network segments R2 (config) # route-map AAA permit 10/route-map is named AAA permit 10, if the conditions specified after the following match command are true, the action is allowed. R2 (config-route-map) # match ip address 1/1 refers to the acl keyword R2 (config) # router ospf 111R2 (config-router) # redistribute rip metric 10 route-map AAA/When the route is deprecated, use the configured route-map to filter the re-published route. In this case, show r3 # show ip routeCodes: C-connected, S-static, R-RIP, M-mobile, B-BGP D-VPN, EX-VPN external, o-OSPF, IA-OSPF inter area N1-ospf nssa external type 1, N2-ospf nssa external type 2 E1-OSPF external type 1, e2-OSPF external type 2 I-IS, su-IS summary, L1-IS level-1, l2-IS level-2 ia-IS inter area, *-candidate default, U-per-user Static route o-ODR, P-periodic downloaded static route Gateway of last resort is not set 1.0.0.0/24 is subnetted, 1 subnetsO E2 1.1.1.0 [110/10] via 23.23.23.1, 00:22:50, ethernet0/1 2.0.0.0/24 is subnetted, 1 subnetsO E2 2.2.2.0 [110/10] via 23.23.23.1, 00:22:50, Ethernet0/1 23.0.0.0/24 is subnetted, 1 subnetsC 23.23.23.23.0 is directly connected, ethernet0/1 only has 1 and 2 network segments.
