3.

  The default gateways are correct.

  The link between the R1 and R2 routers is working and verified.

So all this tells us is that it’s now time to check our routing tables! We’ll start with the 

R1 router:

R1#

sh ipv6 route

C   2001:DB8:3C4D:2::/64 [0/0]

     via FastEthernet0/1, directly connected

L   2001:DB8:3C4D:2:21A:6DFF:FE37:A44F/128 [0/0]

     via FastEthernet0/1, receive

C   2001:DB8:3C4D:3::/64 [0/0]

     via FastEthernet0/0, directly connected

L   2001:DB8:3C4D:3:21A:6DFF:FE37:A44E/128 [0/0]

     via FastEthernet0/0, receive

L   FF00::/8 [0/0]

     via Null0, receive

All we can see in the output is the two directly connected interfaces configured on the 

router, and that won’t help us send IPv6 packets to the 2001:db8:3c4d:1::/64 subnet off of 

Fa0/0 on R2. So let’s find out what R2 can tell us:

R2#

sh ipv6 route

C   2001:DB8:3C4D:1::/64 [0/0]

     via FastEthernet0/0, directly connected

L   2001:DB8:3C4D:1:21A:6DFF:FE37:A443/128 [0/0]

     via FastEthernet0/0, receive

C   2001:DB8:3C4D:2::/64 [0/0]

     via FastEthernet0/1, directly connected

L   2001:DB8:3C4D:2:21A:6DFF:FE64:9B3/128 [0/0]

     via FastEthernet0/1, receive
