Loopback0 10.10.10.1/24 Loopback0 10.10.11.1/24
六、 实验步骤
第一步&＃xff1a;路由器环回接口的配置&＃xff08;其他接口配置请参见实验三&＃xff09;
路由器A&＃xff1a;
Router-A_config#interface loopback0Router-A_config_l0#ip address 10.10.10.1 255.255.255.0
路由器B&＃xff1a;
Router-B#config
Router-B_config#interface loopback0
Router-B_config_l0#ip address 10.10.11.1 255.255.255.0
第二步&＃xff1a;验证接口配置
Router-B#sh interface loopback0
Loopback0 is up, line protocol is up
Hardware is Loopback
Interface address is 10.10.11.1/24
MTU 1514 bytes, BW 8000000 kbit, DLY 500 usec
Encapsulation LOOPBACK
第三步&＃xff1a;路由器的OSPF 配置
A 的配置&＃xff1a;
Router-A_config#router ospf 2 &＃xff01;启动OSPF 进程&＃xff0c;进程号为 2
Router-A_config_ospf_1#network 10.10.10.0 255.255.255.0 area 0 &＃xff01;注意要写掩码和区域号
Router-A_config_ospf_1#network 192.168.1.0 255.255.255.0 area 0
B 的配置&＃xff1a;
Router-B_config#router ospf 1
Router-B_config_ospf_1#network 10.10.11.0 255.255.255.0 area 0
Router-B_config_ospf_1#network 192.168.1.0 255.255.255.0 area 0
第四步&＃xff1a;查看路由表
路由器A&＃xff1a;
Router-A#sh ip route
Codes: C - connected, S - static, R - RIP, B - BGP, BC - BGP connected
D - DEIGRP, DEX - external DEIGRP, O - OSPF, OIA - OSPF inter area
ON1 - OSPF NSSA external type 1, ON2 - OSPF NSSA external type 2
OE1 - OSPF external type 1, OE2 - OSPF external type 2
DHCP - DHCP type
VRF ID: 0
C 10.10.10.0/24 is directly connected, Loopback0
O 10.10.11.1/32 [110,1600] via 192.168.1.2(on Serial1/1)
&＃xff01;注意到环回接口产生的是主机路由
C 192.168.1.0/24 is directly connected, Serial1/1
路由器B&＃xff1a;
Router-B#show ip routeCodes: C - connected, S - static, R - RIP, B - BGP, BC - BGP connected
D - DEIGRP, DEX - external DEIGRP, O - OSPF, OIA - OSPF inter area
ON1 - OSPF NSSA external type 1, ON2 - OSPF NSSA external type 2
OE1 - OSPF external type 1, OE2 - OSPF external type 2
DHCP - DHCP type
VRF ID: 0
O 10.10.10.1/32 [110,1601] via 192.168.1.1(on Serial1/0) &＃xff01;注意管理距离为110
C 10.10.11.0/24 is directly connected, Loopback0
C 192.168.1.0/24 is directly connected, Serial1/0
第五步&＃xff1a;其他验证命令
Router-B#sh ip ospf 1 &＃xff01;显示该OSPF 进程的信息
OSPF process: 1, Router ID: 192.168.2.1
