Lab 3. IPv6 Routing – RIPnG

In IPv6 there are dynamic routing IGP i.e. RIPnG, OSPFv3, and EIGRP

R1#

ipv6 unicast-routing

interface Loopback0

 ipv6 address 1::1/128

interface FastEthernet0/0

 ipv6 address FE80::1 link-local          --- -> create link-local unicast address manually

 ipv6 address 12::1/126                       --- -> create global unicast address

 ipv6 address 21::/64 eui-64                --- ->  create EUI-64 Address

 ipv6 address autoconfig                     --- -> create link-local automatically

 ipv6 enable

R2#

ipv6 unicast-routing

interface Loopback0

 ipv6 address 2::2/128

interface FastEthernet0/0

 ipv6 address FE80::2 link-local

 ipv6 address 12::2/126

 ipv6 address 21::/64 eui-64

 ipv6 address autoconfig

 ipv6 enable

  

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

R1(config)#do sh ipv6 rout

IPv6 Routing Table - 6 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

LC  1::1/128 [0/0]

     via ::, Loopback0

C   12::/126 [0/0]

     via ::, FastEthernet0/0

L   12::1/128 [0/0]

     via ::, FastEthernet0/0

C   21::/64 [0/0]

     via ::, FastEthernet0/0

L   21::1/128 [0/0]

     via ::, FastEthernet0/0

L   FF00::/8 [0/0]

     via ::, Null0

Let’s activate the RIP in interface

R1(config)#int f0/0

R1(config-if)#ipv6 rip 1 enable

R1(config-if)#int lo0

R1(config-if)#ipv6 rip 1 ena

R2(config)#int f0/0

R2(config-if)#ipv6 rip 1 ena

R2(config-if)#int lo0

R2(config-if)#ipv rip 1 ena

Let’s check routing table and make sure R2 can ping loopback R1 and vice versa

R2(config-if)#do sh ipv rou

IPv6 Routing Table - 7 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

R   1::1/128 [120/2]

     via FE80::1, 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

C   21::/64 [0/0]

     via ::, FastEthernet0/0

L   21::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 = 16/30/64 ms
