EIGRP和OSPF做雙點雙向重分發
第一種情況: 1,R1,R2,R3,R4初始配置
R1 conf t int l 0 ip add 1.1.1.1 255.255.255.255 int f0/0 ip add 1.1.123.1 255.255.255.0 no shut router eigrp 1 no auto net 1.1.1.1 0.0.0.0 net 1.1.123.0 0.0.0.255 end
R2 conf t int l 0 ip add 1.1.2.2 255.255.255.255 int f0/0 ip add 1.1.123.2 255.255.255.0 no shut int s1/0 ip add 1.1.234.2 255.255.255.0 encap f no arp f no frame inv frame map ip 1.1.234.4 204 b frame map ip 1.1.234.3 204 b no shut ip ospf p 0 router ospf 1 router-id 1.1.2.2 net 1.1.234.2 0.0.0.0 a 0 net 1.1.2.2 0.0.0.0 a 0 router eigrp 1 no auto net 1.1.2.2 0.0.0.0 net 1.1.123.0 0.0.0.255 end
R3 conf t int l 0 ip add 1.1.3.3 255.255.255.255 int f 0/0 ip add 1.1.123.3 255.255.255.0 no shut int s1/0 ip add 1.1.234.3 255.255.255.0 encap f no arp f no frame inv frame map ip 1.1.234.4 304 b frame map ip 1.1.234.2 304 b no shut ip ospf p 0 router ospf 1 router-id 1.1.3.3 net 1.1.234.3 0.0.0.0 a 0 net 1.1.3.3 0.0.0.0 a 0 router eigrp 1 no auto net 1.1.3.3 0.0.0.0 net 1.1.123.0 0.0.0.255 end
R4 conf t int l 0 ip add 1.1.4.4 255.255.255.255 int s1/0 ip add 1.1.234.4 255.255.255.0 encap f no arp f no frame inv frame map ip 1.1.234.2 402 b frame map ip 1.1.234.3 403 b no shut router ospf 1 router-id 1.1.4.4 nei 1.1.234.2 nei 1.1.234.3 net 1.1.234.4 0.0.0.0 a 0 net 1.1.4.4 0.0.0.0 a 0 end
到這裡(電腦自動關機),所有的EIGRP和OSPF鄰居關系都建立好了。
2,在R2和R3上做雙點雙向重分發
R2 router eigrp 1 redistribute ospf 1 metric 10000 100 255 1 1500 router ospf 1 redistribute eigrp 1 metric 100 metric-type 1 subnets end
R3 router eigrp 1 redistribute ospf 1 metric 10000 100 255 1 1500 router ospf 1 redistribute eigrp 1 metric 100 metric-type 1 subnets end
重分發完成,
驗證
R1路由表
R1#sh ip route
Gateway of last resort is not set
1.0.0.0/8 is variably subnetted, 6 subnets, 2 masks D EX 1.1.4.4/32 [170/284160] via 1.1.123.3, 00:01:03, FastEthernet0/0 [170/284160] via 1.1.123.2, 00:01:03, FastEthernet0/0 D 1.1.3.3/32 [90/156160] via 1.1.123.3, 00:08:44, FastEthernet0/0 D 1.1.2.2/32 [90/156160] via 1.1.123.2, 00:08:44, FastEthernet0/0 C 1.1.1.1/32 is directly connected, Loopback0 C 1.1.123.0/24 is directly connected, FastEthernet0/0 D EX 1.1.234.0/24 [170/284160] via 1.1.123.3, 00:02:51, FastEthernet0/0 [170/284160] via 1.1.123.2, 00:02:51, FastEthernet0/0
R4路由表 R4#sh ip route
Gateway of last resort is not set
1.0.0.0/8 is variably subnetted, 6 subnets, 2 masks C 1.1.4.4/32 is directly connected, Loopback0 O 1.1.3.3/32 [110/65] via 1.1.234.3, 00:00:14, Serial1/0 O 1.1.2.2/32 [110/65] via 1.1.234.2, 00:00:14, Serial1/0 O E1 1.1.1.1/32 [110/164] via 1.1.234.3, 00:00:14, Serial1/0 [110/164] via 1.1.234.2, 00:00:14, Serial1/0 O E1 1.1.123.0/24 [110/164] via 1.1.234.3, 00:00:14, Serial1/0 [110/164] via 1.1.234.2, 00:00:14, Serial1/0 C 1.1.234.0/24 is directly connected, Serial1/0
第二種情況 在R1的S1/2接口接入R5,並啟用RIPV2 R5 conf t int s1/2 ip add 192.168.45.5 255.255.255.0 no shut router rip ver 2 no auto net 192.168.45.0 end
R1 conf t int s1/2 no shut ip add 192.168.45.4 255.255.255.0 router rip ver 2 no au net 192.168.45.0 end
把RIP再分發到EIGRP1中 router eigrp 1 redistribute rip metric 10000 100 255 1 1500 end
這時看R2和R3上的路由表
