주제: R1--->R2<---R3 을 Partial mesh로 구성하고 RIP을 올린다음
R2측에서서 Split-horizon이 enable가 되었을 경우와 no ip split-horizon으로 disable 시켰을경우
table를 관찰한다.
R2에 Split-horizon이 켜있는 상태
R1#sh ip route
Gateway of last resort is not set
1.0.0.0/8 is variably subnetted, 3 subnets, 2 masks
R 1.1.2.0/24 [120/1] via 1.1.123.2, 00:00:11, Serial0
C 1.1.9.0/28 is directly connected, Loopback1
C 1.1.123.0/24 is directly connected, Serial0
9.0.0.0/24 is subnetted, 1 subnets
C 9.9.1.0 is directly connected, Loopback2
R2에 Split-horizon이 껐을 경우
R1#sh ip route
1.0.0.0/8 is variably subnetted, 6 subnets, 2 masks
R 1.1.2.0/24 [120/1] via 1.1.123.2, 00:00:14, Serial0
R 1.1.3.0/24 [120/2] via 1.1.123.2, 00:00:14, Serial0
R 1.1.4.0/24 [120/3] via 1.1.123.2, 00:00:14, Serial0
C 1.1.9.0/28 is directly connected, Loopback1
R 1.1.34.0/24 [120/2] via 1.1.123.2, 00:00:14, Serial0
C 1.1.123.0/24 is directly connected, Serial0
9.0.0.0/24 is subnetted, 1 subnets
C 9.9.1.0 is directly connected, Loopback2
R2#sh ip int serial 0.123
Serial0.123 is up, line protocol is up
Internet address is 1.1.123.2/24
Broadcast address is 255.255.255.255
Address determined by setup command
MTU is 1500 bytes
Helper address is not set
Directed broadcast forwarding is disabled
Multicast reserved groups joined: 224.0.0.9
Outgoing access list is not set
Inbound access list is not set
Proxy ARP is enabled
Security level is default
Split horizon is enabled
R2(config)#interface serial 0.123
R2(config-subif)#no ip split-horizon <----껏을 경우 Rip의 정보가 넘어 온다.R1으로 또 R3으로 교환됨
아래는 R3의값
R3#sh ip route
1.0.0.0/24 is subnetted, 5 subnets
R 1.1.2.0 [120/1] via 1.1.123.2, 00:00:27, Serial0.123
C 1.1.3.0 is directly connected, Loopback0
R 1.1.4.0 [120/1] via 1.1.34.4, 00:00:18, Serial0.34
C 1.1.34.0 is directly connected, Serial0.34
C 1.1.123.0 is directly connected, Serial0.123
R 9.0.0.0/8 [120/2] via 1.1.123.2, 00:00:00, Serial0.123
R3#sh ip route
1.0.0.0/24 is subnetted, 6 subnets
R 1.1.1.0 [120/2] via 1.1.123.2, 00:00:00, Serial0.123
R 1.1.2.0 [120/1] via 1.1.123.2, 00:00:00, Serial0.123
C 1.1.3.0 is directly connected, Loopback0
R 1.1.4.0 [120/1] via 1.1.34.4, 00:00:17, Serial0.34
C 1.1.34.0 is directly connected, Serial0.34
C 1.1.123.0 is directly connected, Serial0.123
R 9.0.0.0/8 [120/2] via 1.1.123.2, 00:00:00, Serial0.123
