**Table 1** Description of the **display ipv6 interface tunnel** command output
Item	Description
Tunnel1 current state	Current status of the tunnel interface: UP: enabled DOWN: disabled When working properly, an IPv6 over IPv4 tunnel is in Up state.
IPv6 protocol current state	Current status of the link layer protocol: UP: enabled DOWN: disabled When working properly, an IPv6 over IPv4 tunnel is in Up state.
IPv6 is enabled	IPv6 is enabled.
link-local address	Link-local address on the interface. After an IPv6 address is configured on the interface, the system automatically assigns a link-local address for the interface. To manually configure a link-local address for an interface, run the ipv6 address link-local command.
Global unicast address(es)	IPv6 global unicast address. To configure an IPv6 global unicast address, run the ipv6 address command.
Joined group address(es)	Addresses of multicast groups that the interface joins.
TENTATIVE	When the interface is in DOWN state, the IPv6 address is TENTATIVE.
MTU	MTU of the interface. To configure the MTU of the interface, run the ipv6 mtu command.
ND reachable time	Reachable time of ND packets.
ND retransmit interval	Interval for retransmitting ND packets.
ND stale time	Time period for the neighbor to keep the STALE state.
ND advertised reachable time	Reachable time of NA packets. NOTE: This field is displayed only after the undo ipv6 nd ra halt command is executed on the interface.
ND advertised retransmit interval	Retransmission interval of NA packets. NOTE: This field is displayed only after the undo ipv6 nd ra halt command is executed on the interface.
ND router advertisement max interval 600 seconds, min interval 200 seconds	Maximum and minimum interval of RA packets. NOTE: This field is displayed only after the undo ipv6 nd ra halt command is executed on the interface.
ND router advertisements live for	Router lifetime in RA packets. NOTE: This field is displayed only after the undo ipv6 nd ra halt command is executed on the interface.
ND router advertisements hop-limit	Hop limit of RA packets. NOTE: This field is displayed only after the undo ipv6 nd ra halt command is executed on the interface.
ND default router preference	Default route priority in RA packets. NOTE: This field is displayed only after the undo ipv6 nd ra halt command is executed on the interface.
Hosts use stateless autoconfig for addresses	Hosts obtain IPv6 addresses by means of stateless auto-configuration. NOTE: This field is displayed only after the undo ipv6 nd ra halt command is executed on the interface.
