目的
- RIPのタイマーを調整し、コンバージェンスを早める方法を確認します。
構成
- 設定概要
- RIPによってルーティングします。

検証1 タイマーの設定
- 認証の確認
show ip protocolコマンドでタイマーを確認します。hello, invalid, hold, flushのタイマーが確認できます。
R1#show ip protocols
Routing Protocol is "rip"
Sending updates every 30 seconds, next due in 21 seconds <- helloが確認できます
Invalid after 180 seconds, hold down 180, flushed after 240 <- invalid, hold, flushが確認できます
Outgoing update filter list for all interfaces is not set
Incoming update filter list for all interfaces is not set
Redistributing: rip
Default version control: send version 1, receive any version
Interface Send Recv Triggered RIP Key-chain
FastEthernet0/0 1 1 2
Loopback0 1 1 2
Automatic network summarization is not in effect
Maximum path: 4
Routing for Networks:
1.0.0.0
192.168.1.0

- タイマーの設定
ripのタイマーを設定します。R1のみ、以下のコマンドを投入します。
R1(config)#router rip R1(config-router)#timers basic 10 30 30 40
- ルーティングテーブルの確認
ルーティングテーブルを確認します。OSPFと違って、RIPはタイマーが違っても経路が交換できるようです。
R1#clear ip route *
R1#show ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP 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-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route
Gateway of last resort is not set
1.0.0.0/32 is subnetted, 1 subnets
C 1.1.1.1 is directly connected, Loopback0
R 2.0.0.0/8 [120/1] via 192.168.1.2, 00:00:02, FastEthernet0/0
C 192.168.1.0/24 is directly connected, FastEthernet0/0
R1#
- タイマーの確認します。
タイマーを再確認します。先ほどのタイマーの変更設定が反映されている事を確認します。
