Lab 4. IPv6 Routing – OSPFv3

R1#

ipv6 unicast-routing

interface Loopback0

 ipv6 address 1::1/128

interface FastEthernet0/0

 ipv6 address 12::1/126                      

 ipv6 enable

R2#

ipv6 unicast-routing

interface Loopback0

 ipv6 address 2::2/128

interface FastEthernet0/0

 ipv6 address 12::2/126

 ipv6 enable

We can do ping ip p2p. But we can not ping to loopback from other router because no any routing table.

 Let’s activate the OSPF. Create ipv6 router ospf first and must have router-id! After creating ipv6 router ospf, need to activate on interface

R1(config)#ipv6 router ospf 1

R1(config-rtr)#

*Mar  1 00:07:23.095: %OSPFv3-4-NORTRID: OSPFv3 process 1 could not pick a router-id,

please configure manually

R1(config-rtr)#router-id 1.1.1.1

R1(config)#int lo0

R1(config-if)#ipv6 ospf 1 area 0

R1(config-if)#int f0/0

R1(config-if)#ipv6 ospf 1 area 0

R2(config-if)#ipv6 router ospf 2

R2(config-rtr)#

*Mar  1 00:08:12.835: %OSPFv3-4-NORTRID: OSPFv3 process 2 could not pick a router-id,

please configure manually

R2(config-rtr)#router-id 2.2.2.2

R2(config)#int lo0

R2(config-if)#ipv6 ospf 2 area 0

R2(config-if)#int f0/0

R2(config-if)#ipv6 ospf 2 area 0

*Mar  1 00:10:14.295: %OSPFv3-5-ADJCHG: Process 1, Nbr 2.2.2.2 on FastEthernet0/0 from LOADING to FULL, Loading Done

Great… OSPF adjacency already up. Let’s check ospfv3 neighbor

R1(config-if)#do sh ipv ospf nei

Neighbor ID     Pri   State                   Dead Time   Interface ID    Interface

2.2.2.2              1      FULL/BDR        00:00:30       4                     FastEthernet0/0

R2(config-if)#do sh ipv ospf nei

Neighbor ID     Pri   State                 Dead Time   Interface ID    Interface

1.1.1.1              1      FULL/DR         00:00:35     4                      FastEthernet0/0

Check routing table and make sure the ping is working

R2(config-if)#do sh ipv rou

IPv6 Routing Table - 5 entries

Codes: C - Connected, L - Local, S - Static, R - RIP, B - BGP

       U - Per-user Static route, M - MIPv6

       I1 - ISIS L1, I2 - ISIS L2, IA - ISIS interarea, IS - ISIS summary

       O - OSPF intra, OI - OSPF inter, OE1 - OSPF ext 1, OE2 - OSPF ext 2

       ON1 - OSPF NSSA ext 1, ON2 - OSPF NSSA ext 2

       D - EIGRP, EX - EIGRP external

O   1::1/128 [110/10]

     via FE80::C200:5FF:FEAC:0, FastEthernet0/0

LC  2::2/128 [0/0]

     via ::, Loopback0

C   12::/126 [0/0]

     via ::, FastEthernet0/0

L   12::2/128 [0/0]

     via ::, FastEthernet0/0

L   FF00::/8 [0/0]

     via ::, Null0

R2(config-if)#do ping 1::1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 1::1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 20/32/44 ms
