CONFIGURING OSPF V3 On all routers
Configure OSPFv6 on R1.
With IPv6, it is common to have multiple IPv6 addresses configured on an interface. The network
statement
has been eliminated in OSPFv3. OSPFv3 routing is enabled at the interface level instead.
a. Issue the ipv6 ospf 1 area 0 command for each interface on R1 that is to participate in OSPFv3 routing.
R1(config)# interface g0/0
R1(config-if)# ipv6 ospf 1 area 0
R1(config-if)# interface s0/0/0
R1(config-if)# ipv6 ospf 1 area 0
R1(config-if)# interface s0/0/1
R1(config-if)# ipv6 ospf 1 area 0
Note: The process ID must match the process ID you used in Step1a.
Configure OSPFv6 onR2.
With IPv6, it is common to have multiple IPv6 addresses configured on an interface. The network
statement
has been eliminated in OSPFv3. OSPFv3 routing is enabled at the interface level instead.
a. Issue the ipv6 ospf 1 area 0 command for each interface on R1 that is to participate in OSPFv3 routing.
R2(config)# interface g0/0
R2(config-if)# ipv6 ospf 1 area 0
R2(config-if)# interface s0/0/0
R2(config-if)# ipv6 ospf 1 area 0
R2(config-if)# interface s0/0/1
R2(config-if)# ipv6 ospf 1 area 0
Note: The process ID must match the process ID you used in Step1a.
Configure OSPFv6 on R3.
With IPv6, it is common to have multiple IPv6 addresses configured on an interface. The network
statement
has been eliminated in OSPFv3. OSPFv3 routing is enabled at the interface level instead.
a. Issue the ipv6 ospf 1 area 0 command for each interface on R1 that is to participate in OSPFv3 routing.
R3(config)# interface g0/0
R3(config-if)# ipv6 ospf 1 area 0
R3(config-if)# interface s0/0/0
R3(config-if)# ipv6 ospf 1 area 0
R3(config-if)# interface s0/0/1
R3(config-if)# ipv6 ospf 1 area 0
Note: The process ID must match the process ID you used in Step1a.
Check the OSPF 3 protocol on all 3 routers
Verify the IPv6 routing table.
Issue the show ipv6 route command to verify that all networks are appearing in the routing table.
R2# show ipv6 route
R1# show ipv6 route
R3# show ipv6 route
R2# show ipv6 route ospf
R1# show ipv6 route ospf
R3# show ipv6 route ospf
R1# show ipv6 ospf nei
R2# show ipv6 ospf nei
R3# show ipv6 ospf nei
Assign IPv6 addresses to PC A, PC B and PC C
Ping the Pc’s and see if they are pinging each other! SUCCESS!
