Ping test from Router1 to Router2:
ping ipv6 2604:3E00:1:1::2 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 2604:3E00:1:1::2, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 4/7/16 ms
We statically set our link-local address so a easily understandable next hope can be determined when we view the routing table. What we do is setup all link-local addresses exactly the same on each router. For example all LL addresses on router1 are: FE80::9, all LL addresses on router2 are: FE80::11, etc... In the example below you can see how this makes it easier for a human to get the next hop.
Router1> show ipv6 route IPv6 Routing Table - default - 11 entries Codes: C - Connected, L - Local, S - Static, U - Per-user Static route B - BGP, HA - Home Agent, MR - Mobile Router, R - RIP I1 - ISIS L1, I2 - ISIS L2, IA - ISIS interarea, IS - ISIS summary D - EIGRP, EX - EIGRP external, ND - Neighbor Discovery O - OSPF Intra, OI - OSPF Inter, OE1 - OSPF ext 1, OE2 - OSPF ext 2 ON1 - OSPF NSSA ext 1, ON2 - OSPF NSSA ext 2 OE2 ::/0 [110/1], tag 2552 via FE80::11, GigabitEthernet1/0 OE2 2000:2000:666::/64 [110/1] via FE80::11, GigabitEthernet1/0 OE2 2000:2000:1000::/64 [110/1] via FE80::11, GigabitEthernet1/0 OE2 2000:2000:2000::/64 [110/1] via FE80::11, GigabitEthernet1/0 OE2 2000:2000:3000::/64 [110/1]
Need to see the IP's associated with the interface, run:
Router1> show ipv6 interface gi 1/0 GigabitEthernet1/0 is up, line protocol is up IPv6 is enabled, link-local address is FE80::9 No Virtual link-local address(es): Global unicast address(es): 2604:3E00:1:1::1, subnet is 2604:3E00:1:1::/64
