1. RIPv1
例）インターフェースeth0/2.1(192.168.255.254/24)でRIPv1によるルーティングを行う。
[[SSG]]-> set vrouter "trust-vr"
SSG(trust-vr)-> set protocol rip
SSG(trust-vr)-> set enable
SSG(trust-vr)-> set version v1
SSG(trust-vr)-> exit
SSG-> set interface ethernet0/2.1 protocol rip enable
2. RIP情報の確認
SSG-> get vrouter "trust-vr" protocol rip

1. Route Filtering
例)RIPにて受信したルートの内、不要なルート(192.168.16.0/24, 192.168.17.0/24)をフィルタリングする。
最初に、RIPの設定を行う。
VRF環境のため、address-familyにてVRF01を指定する。
router rip
address-family ipv4 vrf VRF01
[[network]] 172.16.0.0
network 192.168.33.0
no auto-summary
version 1
exit-address-family
exit
ルートフィルタリング適用前のルーティングテーブル
Switch(config)#do show ip route vrf VRF01
Load for five secs: 7%/0%; one minute: 10%; five minutes: 9%
Time source is [[NTP]], 02:54:18.860 JST Sun Dec 22 2013
[[Routing]] Table: VRF01
Codes: C - connected, S - static, R - RIP, M - mobile, B - [[BGP]]
D - EIGRP, EX - EIGRP external, O - [[OSPF]], IA - OSPF inter area

Gateway of last resort is 192.168.255.254 to network 0.0.0.0

R* 0.0.0.0/0 [120/1] via 192.168.255.254, 00:00:28, Vlan997
Prefix-listにより192.168.16.0/22 ～ 24の範囲のルートをフィルタリング対象とする。
それいがいのルートは全て受け付ける。
ip prefix-list rip-list01 seq 5 deny 192.168.16.0/22 le 24
ip prefix-list rip-list01 seq 10 permit 0.0.0.0/0 le 32
RIPにフィルタリングをIN方向で適用する。
router rip
address-family ipv4 vrf VRF01
distribute-list prefix rip-list01 in
exit-address-family
exit
