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
Nice! Just what I was looking for. :-)
ReplyDeletein my gns3 ipv6 is not supporting....what may be the reason????
ReplyDeleteMake sure you have enabled IPv6 routing by following command:
DeleteR1(config)# ipv6 unicast-routing
still if you are unable to run IPv6 then you need some updated IOS with IPv6 features mostly i have tried 7200 series IOS for IPv6 you can download IOS for GNs3 from this link,,!
Excellent example for star to understand IPV6 configuration.
ReplyDeletegetting this things internet protocol disable
ReplyDeletehow can fix it
R1#show ip int
R1#show ip interface lo
R1#show ip interface loopback 0
Loopback0 is up, line protocol is up
Internet protocol processing disabled
R1#
after the command "R1(config-if)# ipv6 ospf 1 area 0" it saying "OSPFv3: No IPV6 enabled on this interface". what to do? as its not taking cmmnds aftr this note
ReplyDeleteEnable the IPv6 routing by using command "ipv6 unicast-routing" then i think you dont have assign any IPV6 address to interface..first assign IPv6 address to that interface..
Deletegood text, I have first time using GNS3 on configuring ipv6 based.
ReplyDeletethanks
show ipv6 ospf 1 neighbor command isnt returning anything. What will my mistake be?
