思科路由器上实测IPV6地址 －应用技巧

对于思科路由器的IPV6实测，我们要进行哪些操作呢？具体的配置命令都有哪些呢？下面的文章讲给你详细的介绍，相信此文会对你有所帮助。

#没有配置ipv6地址的接口

r1#sh run int fa1/0

interface FastEthernet1/0

ip address 172.16.12.1 255.255.255.0

duplex auto

speed auto

end

r1#sh ipv6 int bri

FastEthernet1/0 [up/up]

unassigned

FastEthernet1/1 [administratively down/down]

unassigned

r1(config)#int fa1/0

r1(config-if)#ipv6 addr ?

WORD General prefix name

X:X:X:X::X IPv6 link-local address

X:X:X:X::X/ IPv6 prefix

autoconfig Obtain address using autoconfiguration

#配置本地链路地址不成功，因为ipv6的link-local地址必须是fe80::/16开头的

r1(config-if)#ipv6 addr 3333::1 link-local

% Invalid link-local address

#先配置ipv6 prefix地址

r1(config-if)#ipv6 addr 3333::1/112

r1(config-if)#do sh run int fa1/0

interface FastEthernet1/0

ip address 172.16.12.1 255.255.255.0

duplex auto

speed auto

ipv6 address 3333::1/112

#配置了prefix地址后，会自动配置link-local

r1#sh ipv6 int bri

FastEthernet1/0 [up/up]

FE80::C800:14FF:FE38:1C

3333::1

FastEthernet1/1 [administratively down/down]

unassigned

#可以手动配置link-local，覆盖掉自动生成的link-local

#一个接口只能有一个link-local，配置多条前面的会被覆盖

#一个接口可配置多条prefix地址

r1(config-if)#ipv6 addr fe80::1 link-local

r1(config-if)#ipv6 addr fe80::1:1 link-local

r1(config-if)#ipv6 addr fe80::3:1:1 link-local

r1(config-if)#ipv6 addr 4444::1/112

r1#sh int fa1/0

interface FastEthernet1/0

ip address 172.16.12.1 255.255.255.0

duplex auto

speed auto

ipv6 address 3333::1/112

ipv6 address 4444::1/112

ipv6 address FE80::3:1:1 link-local

end
