Lab 5. IPv6 Routing – EIGRP

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.

R1(config)#ipv6 router eigrp 1

R1(config-rtr)#router-id 1.1.1.1

R1(config-rtr)#no shut                                      ---- -> must be activated in EIGRP IPv6

R1(config-rtr)#int lo0

R1(config-if)#ipv eigrp 1

R1(config-if)#int f0/0

R1(config-if)#ipv eigrp 1

R2(config)#ipv6 router eigrp 1

R2(config-rtr)#router-id 2.2.2.2

R2(config-rtr)#no shut

R2(config-rtr)#int lo0

R2(config-if)#ipv eigrp 1

R2(config-if)#int f0/0

R2(config-if)#ipv eigrp 1

*Mar  1 00:15:56.683: %DUAL-5-NBRCHANGE: IPv6-EIGRP(0) 1: Neighbor FE80::C200:5FF:FEAC:0 (FastEthernet0/0) is up: new adjacency

Yes… the neighbor adjacency already up. Check the routing table

R1(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

LC  1::1/128 [0/0]

     via ::, Loopback0

D   2::2/128 [90/409600]

     via FE80::C201:5FF:FEAC:0, FastEthernet0/0

C   12::/126 [0/0]

     via ::, FastEthernet0/0

L   12::1/128 [0/0]

     via ::, FastEthernet0/0

L   FF00::/8 [0/0]

     via ::, Null0

Make sure ping is ok

R1(config-if)#do ping 2::2 

Type escape sequence to abort.

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

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 8/24/56 ms
