Maipu Administration Guide

Configure RIPng Route Filtration

Network Requirements

Run RIPng between Device1 and Device2 for route interaction.
Device1 has learnt the two routes 2001:2::/64 and 2001:3::/64 advertised by Device2, and then, the route 2001:3::/64 is filtered in the advertising direction of Device2.

Configuration Steps

Step 1: Create VLANs, and add ports to the required VLANs. (Omitted)

Step 2: Configure the IPv6 address of an interface (omitted).

Step 3: Configure RIPng.

#Configure Device1.

Device1#configure terminal
Device1(config)#ipv6 router rip 100
Device1(config-ripng)#exit
Device1(config)#interface vlan2
Device1(config-if-vlan2)#ipv6 rip enable 100
Device1(config-if-vlan2)#exit

#Configure Device2.

Device2#configure terminal
Device2(config)#ipv6 router rip 100
Device2(config-ripng)#exit
Device2(config)#interface vlan2
Device2(config-if-vlan2)#ipv6 rip enable 100
Device2(config-if-vlan2)#exit
Device2(config)#interface vlan3
Device2(config-if-vlan3)#ipv6 rip enable 100
Device2(config-if-vlan3)#exit
Device2(config)#interface vlan4
Device2(config-if-vlan4)#ipv6 rip enable 100
Device2(config-if-vlan4)#exit

#View the IPv6 route table of Device1.

Device1#show ipv6 route 
Codes: C - Connected, L - Local, S - static, R - RIP, B - BGP, i-ISIS 
       U - Per-user Static route 
       O - OSPF, OE-OSPF External, M - Management 
 
L ::1/128 [0/0] 
     via ::, 2w5d:02:47:44, lo0
C 2001:1::/64 [0/0] 
     via ::, 00:56:34, vlan2
L 2001:1::1/128 [0/0] 
     via ::, 00:56:32, lo0
R 2001:2::/64 [120/2] 
     via fe80::201:7aff:fec3:38a4, 00:27:11, vlan2
R  2001:3::/64 [120/2] 
     via fe80::201:7aff:fec3:38a4, 00:27:11, vlan2

You can see that Device1 has learnt the two routes advertised by Device2.

Step 4: Configure the IPv6 prefix list.

Device2(config)#ipv6 prefix-list RIPng deny 2001:3::/64

Step 5: Configure the route filtration.

#Configure route filtering in the output direction of interface vlan2 of Device2.

Device2(config)#ipv6 router rip 100
Device2(config-ripng)#distribute-list prefix RIPng out vlan2
Device2(config-ripng)#exit

Step 6: Check the result.
