IPV6 Configuration in Gns3:


IPV6 OSPF Configuration on Gns3:

This is the simple IPV6 tutorial for configuring IPV6 and OSPF for IPV6 on Gns3.  You must enable IPV6 routing on router by using command “ipv6 unicast-routing”, all other command are same like normal IP configuration but just replace IP with IPV6 in all commands. I use the c7200 IOS for this lab. Configure the topology as below:

R1 Configuration:
R1(config)#  ipv6 unicast-routing
R1(config)#  ipv6 router ospf 1
 R1(config-router)#  router-id 1.1.1.1
R1(config-router)# exit
R1(config-if)#  interface Loopback1
R1(config-if)#  ipv6 address 2001:211:10:1::1/64
 R1(config-if)#  ipv6 ospf 1 area 0
R1(config-if)#  interface Serial1/0
R1(config-if)#  ipv6 address 2001:210:10:1::2/64
R1(config-if)#  ipv6 ospf 1 area 0

R2 Configuration:

R2(config)#  ipv6 unicast-routing
R2(config)#  ipv6 router ospf 1
 R2(config-router)#  router-id 2.2.2.2
R2(config-router)# exit
R2(config-if)#  interface Loopback1
R2(config-if)#  ipv6 address 2001:211:10:1::2/64
 R2(config-if)#  ipv6 ospf 1 area 0
R2(config-if)#  interface Serial1/0
R2(config-if)#  ipv6 address 2001:210:10:1::1/64
R2(config-if)#  ipv6 ospf 1 area 0

IPV6 Verification Commands:
R# show ipv6 route
R# SHOW ipv6 interface brief
R# SHOW ipv6 ospf 1 neighbor
