FastEthernet0/0 is up, line protocol is up
IPv6 is enabled, link-local address is FE80::128C:CFFF:FE2E:916E

MTU is 1500 bytes
ICMP error messages limited to one every 100 milliseconds
ICMP redirects are enabled
ICMP unreachables are sent
ND DAD is enabled, number of DAD attempts: 1
ND reachable time is 30000 milliseconds (using 30000)
ND advertised reachable time is 0 (unspecified)
ND advertised retransmit interval is 0 (unspecified)
ND router advertisements are sent every 200 seconds
ND router advertisements live for 1800 seconds
ND advertised default router preference is Medium
Hosts use stateless autoconfig for addresses.Default IPv6 Unicast Route
Notice the 2000::/3 prefix which identifies the total IPv6 Unicast area. It is recomended to use link local address as next-hop address. If using the Global Unicast address Router redirection will not work.
