and also for further IPV6 analysis:
sh ipv6 int
LI-Null0 is up, line protocol is up
  IPv6 is enabled, link-local address is FE80::218:74FF:FE16:D180
  No global unicast address is configured
  Joined group address(es):
  MTU is 1500 bytes
  ICMP error messages limited to one every 100 milliseconds
  ICMP redirects are enabled
  ND DAD is not supported
  ND reachable time is 30000 milliseconds

Just wondering if anyone else sees this behavior?
