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

OSPF Non-Broadcast Configuration on gns3 (OSPF frame-Relay Configuration Lab):

Frame-Relay Hub and spoke Configuration:

In OSPF non-broadcast mode has following features:

·         All Router Must be on Same Subnet

·         Statically configure the Neighbors

·         Act Like a LAN Environment

·         DR/BDR are selected, since there is not broadcast therefore you select DR and DR-other by priority command.

GNS3 Frame-Relay switch Configuration:

Add the mapping as shown in figure for given topology.

R1 Configuration:

interface Serial1/0

 ip address 10.1.1.1 255.255.255.0

 encapsulation frame-relay

 ip ospf priority 255

 ip ospf 1 area 0

 serial restart-delay 0

 frame-relay map ip 10.1.1.2 200 broadcast

 frame-relay map ip 10.1.1.3 300 broadcast

router ospf 1

 router-id 1.1.1.1

 log-adjacency-changes

 neighbor 10.1.1.2 priority 0

 neighbor 10.1.1.3 priority 0

ip ospf priority 255

R2 Configuration:

interface Loopback1

 ip address 200.1.1.1 255.255.255.0

 ip ospf priority 0

 ip ospf 1 area 0

interface Serial1/0

 ip address 10.1.1.2 255.255.255.0

 encapsulation frame-relay

 ip ospf priority 0

 ip ospf 1 area 0

frame-relay map ip 10.1.1.1 100 broadcast

 frame-relay map ip 10.1.1.3 100 broadcast

router ospf 1

router-id 2.2.2.2

R3 Configuration:

interface Serial1/0

 ip address 10.1.1.3 255.255.255.0

 encapsulation frame-relay

 ip ospf priority 0

 ip ospf 1 area 0

 serial restart-delay 0

 frame-relay map ip 10.1.1.1 100 broadcast

 frame-relay map ip 10.1.1.2 100 broadcast

router ospf 1

 router-id 3.3.3.3

Verification commands:

Show frame-rel ay map

Show ip route

Show ip ospf 1 neighbour

Show ip ospf 1 process

1. Ping all other router should be successful.
2. Use the traceroute command to verify that R1 is hub and other are spoke.
