IPv6 Configuration-2 (RIPng)

IPv6 的RIP,和IPv4下的RIPv2基本上同，不同的是IPv4 RIPv2使用UDP 端口520,RIPng使用的是UDP 521,IPv4 RIPv2数据包更新使用地址224.0.0.9 ,RIPng使用的地址为FF02::9

在配置RIPng的时候，方法和Ipv4是由区别的，RIPng采用先配置进程，然后在相应的接口下配置。

下面是用一个例子来说明如何配置RIPng

1 网络连接图形为

设备名称	接口	接口IP	备注
R1	Fa0/0	2012:1:1:11::1/64
	loopback1	3001:1:1:11::1/64
	loopback2	3002:1:1:11::1/64
	loopback3	3003:1:11:11::1/64
R2	Fa0/0	2012:1:1:11::2/64
	loopback0	2022:2:2:22::2/64

2 R1的初始化配置

R1(config)#ipv6 unicast-routing

R1(config)#interface fa0/0

R1(config-if)#ipv6 address 2012:1:1:11::1/64

R1(config)#interface loopback1

R1(config-if)#ipv6 address 3001:1:1:11::1/64

R1(config)#interface loopback3

R1(config-if)#ipv6 address 3002:1:1:11::1/64

R1(config)#interface loopback3

R1(config-if)#ipv6 address 3003:1:1:11::1/64

 R2初始化配置

R2(config)#ipv6 unicast-routing

R2(config)#interface fa0/0

R2(config-if)#ipv6 address 2012:1:1:11::2/64

R2(config)#interface loopback0

R2(config-if)#ipv6 address 2022:2:2:22::2/64

3 启动RIPng进程

Cisco IOS最多同时支持4个RIPng进程，不同进程使用不同的名字处理

3.1 R1/R2上启动RIPng进程

R1(config)#ipv6 router rip ccie

R2(config)#ipv6 router rip ccie

4 在接口上启用RIPng进程

R1(config)#interface fa0/0

R1(config-if)#ipv6 rip ccie enable

R1(config)#interface loopback1

R1(config-if)#ipv6 rip ccie enable

R2(config)#interface fa0/0

R2(config-if)#ipv6 rip ccie enable

R2(config)#interface loopback0

R2(config-if)#ipv6 rip ccie enable

5 查看RIPng路由

5.1 查看R1上的RIPng路由

R1#show ipv6 router rip

IPv6 Routing Table - 11 entries

Codes: C - Connected, L - Local, S - Static, R - RIP, B - BGP

       U - Per-user Static route

       I1 - ISIS L1, I2 - ISIS L2, IA - ISIS interarea, IS - ISIS summary

       O - OSPF intra, OI - OSPF inter, OE1 - OSPF ext 1, OE2 - OSPF ext 2

       ON1 - OSPF NSSA ext 1, ON2 - OSPF NSSA ext 2

       D - EIGRP, EX - EIGRP external

R   2022:2:2:22::/64 [120/2]

     via FE80::C200:DFF:FEC4:0, FastEthernet0/0

5.2 查看R2 上的RIPng路由

R2#show ipv6 route rip

IPv6 Routing Table - 7 entries

Codes: C - Connected, L - Local, S - Static, R - RIP, B - BGP

       U - Per-user Static route

       I1 - ISIS L1, I2 - ISIS L2, IA - ISIS interarea, IS - ISIS summary

       O - OSPF intra, OI - OSPF inter, OE1 - OSPF ext 1, OE2 - OSPF ext 2

       ON1 - OSPF NSSA ext 1, ON2 - OSPF NSSA ext 2

       D - EIGRP, EX - EIGRP external

R   3001:1:1:11::/64 [120/2]

     via FE80::C200:BFF:FE48:0, FastEthernet0/0

5.3 测试连通性质

测试R1到对段链路本地地址的连通性

R1#ping FE80::C200:DEF:FEC4:0

Output Interface: FastEthernet0/0          

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to FE80::C200:DFF:FEC4:0, timeout is 2 seconds:

Packet sent with a source address of FE80::C200:DFF:FEC4:0

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 32/70/184 ms

测试R1到对端IPv6网络的连通性

R1#ping 2022:2:2:22::2

 

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 2022:2:2:22::2, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 12/75/240 ms

同样可以测试R2

6 重发布IPv6

6.1 将R1中剩余网段重发布到RIPng中

R1中进行再发布工作

R1(config)#route-map conn permit 10

R1(config-route-map)#match interface loopback2

R1(config)#route-map conn permit 20

R1(config-route-map)#match interface loopback3

R1(config)#ipv6 router rip ccie

R1(config)#redistribute connected route-map con

6.2 在R2行查看重发布的RIPng剩余网段

R2#show ipv6 route rip

IPv6 Routing Table - 9 entries

Codes: C - Connected, L - Local, S - Static, R - RIP, B - BGP

       U - Per-user Static route

       I1 - ISIS L1, I2 - ISIS L2, IA - ISIS interarea, IS - ISIS summary

       O - OSPF intra, OI - OSPF inter, OE1 - OSPF ext 1, OE2 - OSPF ext 2

       ON1 - OSPF NSSA ext 1, ON2 - OSPF NSSA ext 2

       D - EIGRP, EX - EIGRP external

R   3001:1:1:11::/64 [120/2]

     via FE80::C200:BFF:FE48:0, FastEthernet0/0

     via FE80::C200:BFF:FE48:0, FastEthernet0/0

R   3003:1:1:11::/64 [120/2]

     via FE80::C200:BFF:FE48:0, FastEthernet0/0

7 过滤IPv6路由

在R2中过滤掉不想要的路由,使用distribute-list 

7.1 配置只保留3002:1:1:11::/64 网段

R2(config)#ipv6 prefix-list abc permit 3002:1:1:11::/64

R2(config)#ipv6 router rip ccie

R2(config-rtr)#distribute-list prefix-list abc in fa0/0

7.2 查看过滤后的路由结果

R2#show ipv6 route rip

r2#show ipv6 route rip

IPv6 Routing Table - 7 entries

Codes: C - Connected, L - Local, S - Static, R - RIP, B - BGP

       U - Per-user Static route

       I1 - ISIS L1, I2 - ISIS L2, IA - ISIS interarea, IS - ISIS summary

       O - OSPF intra, OI - OSPF inter, OE1 - OSPF ext 1, OE2 - OSPF ext 2
