CISCO 路由器IPV6相关快速配置 思科ipv6

#文章首发挑战赛#

本文以实例介绍CISCO路由器IPV6的相关配置。

拓扑如图：设备全部需要支持IPv6

IPV6基本配置

R1配置

hostname R1

ipv6 unicast-routing

//开启IPv6支持

interface GigabitEthernet0/0

ipv6 address 2001::1/64

//接口配置地址

ipv6 route ::/0 2001::2

//配置默认路由

R2 配置

hostname R2

ipv6 unicast-routing

interface GigabitEthernet0/0

ipv6 address 2001::2/64

interface GigabitEthernet0/1

ipv6 address 2002::2/64

R3 配置

hostname R3

ipv6 unicast-routing

interface GigabitEthernet0/1

ipv6 address 2002::3/64

ipv6 route ::/0 2002::2

配置完成后查看

接口下自动生成链路本地地址

IPv6路由表中的静态默认路由和直连路由

PING测试R3正常

OSPF V3 (IPv6的OSPF)快速配置

各台路由器配置环回口，并宣告进OSPFV3，全网互通。

R1

ipv6 router ospf 110

router-id 1.1.1.1

//配置OSPFv3，手动配置RID

interface Loopback0

ipv6 address 2010::1/128

ipv6 ospf 110 area 0

//配置Loo0地址，宣告进OSPFV3

interface GigabitEthernet0/0

ipv6 address 2001::1/64

ipv6 ospf 110 area 0

ipv6 ospf network point-to-point

////配置几口地址，宣告进OSPFV3，接口类型修改为p2p加快收敛

R2

ipv6 router ospf 110

router-id 2.2.2.2

interface Loopback0

ipv6 address 2011::1/128

ipv6 ospf 110 area 0

interface GigabitEthernet0/0

ipv6 address 2001::2/64

ipv6 ospf 110 area 0

ipv6 ospf network point-to-point

interface GigabitEthernet0/1

ipv6 address 2002::2/64

ipv6 ospf 110 area 0

R3配置

ipv6 router ospf 110

router-id 3.3.3.3

interface Loopback0

ipv6 address 2012::1/128

ipv6 ospf 110 area 0

interface GigabitEthernet0/1

ipv6 address 2002::3/64

ipv6 ospf 110 area 0

配置完成后，检查路由器OSPFV3邻居

查看OSPFV3路由表

查看系统路由表，链路本地地址不会加表，路由的下一跳是对端接口的链路本地地址。

全网互通正常。

IPV6 Eigrp的快速配置

R1

ipv6 router eigrp 90

eigrp router-id 1.1.1.1

//配置IPV6 Eigrp，手工配置RID

interface Loopback0

ipv6 address 2010::1/128

ipv6 eigrp 90

interface GigabitEthernet0/0

ipv6 address 2001::1/64

ipv6 eigrp 90

//配置接口IPV6地址，宣告进Eigrp

R2

ipv6 router eigrp 90

eigrp router-id 2.2.2.2

interface Loopback0

ipv6 address 2011::1/128

ipv6 eigrp 90

interface GigabitEthernet0/0

ipv6 address 2001::2/64

ipv6 eigrp 90

ipv6 ospf network point-to-point

interface GigabitEthernet0/1

ipv6 address 2002::2/64

ipv6 eigrp 90

R3

ipv6 router eigrp 90

eigrp router-id 3.3.3.3

interface Loopback0

ipv6 address 2012::1/128

ipv6 eigrp 90

interface GigabitEthernet0/1

ipv6 address 2002::3/64

ipv6 eigrp 90

配置完成后检查Eigrp邻居表 拓扑表 路由表

PING测全网互通正常

IPV6穿越IPV4快速配置

拓扑中三台设备组成传统IPV4网络，R1 R3各配置一个IPv6d Loo0口模拟IPv6末节网络，两LO口穿越IPv4互通。

R1配置

hostname R1

interface Loopback0

ipv6 address 2001::1/128

interface GigabitEthernet0/0

ip address 12.0.0.1 255.255.255.0

router eigrp 90

network 12.0.0.0

//配置基础接口IP，Eigrp协议互通

interface Tunnel0

ipv6 address 2010::1/64

tunnel source 12.0.0.1

tunnel mode ipv6ip

tunnel destination 23.0.0.2

//配置GRE tunnel接口，接口源目IPV4地址，IPv6地址，模式ipv6穿越ipv4

ipv6 route ::/0 Tunnel0

//配置ipv6默认路由下一跳出口为Tunnel口

R2配置

hostname R2

interface GigabitEthernet0/0

ip address 12.0.0.2 255.255.255.0

interface GigabitEthernet0/1

ip address 23.0.0.1 255.255.255.0

router eigrp 90

network 12.0.0.0

network 23.0.0.0

R3配置

hostname R3

interface Loopback0

ipv6 address 2002::1/128

interface Tunnel0

ipv6 address 2010::2/64

tunnel source 23.0.0.2

tunnel mode ipv6ip

tunnel destination 12.0.0.1

interface GigabitEthernet0/1

ip address 23.0.0.2 255.255.255.0

router eigrp 90

network 23.0.0.0

ipv6 route ::/0 Tunnel0

配置完成后检查R1路由表

测试两Loo0口IPv6地址互通正常。
