ND reachable time is 30000 milliseconds

ND retransmit interval is 1000 milliseconds

Hosts use stateless autoconfig for addresses 

encapsulation-limit [ number ]

Tunnel interface view

number: Number of nested encapsulations in a tunnel, in the range of 1 to 10. 
The default value is 4.

Use the encapsulation-limit command to configure the maximum number of 
nested encapsulations of a packet.

Use the undo encapsulation-limit command to remove the encapsulation 
limit.

The encapsulation limit is only applicable to the IPv6 over IPv6 tunnel.

# Configure the maximum number of nested encapsulations in a tunnel to 3.

Table 190   Description on fields of the display interface tunnel command

Tunnel0 current state: UP 

The physical layer of the tunnel interface is reachable. 

Line protocol current state: UP 

The link layer of the tunnel interface is reachable. 

IPv6 is enabled 

Enables IPv6 on a tunnel interface 

link-local address 

Link-local address of a tunnel interface 

Global unicast address(es) 

Aggregatable global unicast address of a tunnel interface. 

Joined group address(es) 

Multicast address of a tunnel interface. 

MTU is 1500 bytes 

Size of the MTU in a tunnel. The MTU in this example is 
1,500 bytes. 

ND reachable time 

Neighbor reachable time 

ND retransmit interval 

Interval for retransmitting a neighbor discovery message. 

Hosts use stateless autoconfig for 
addresses 

Hosts use the stateless auto-configuration mode to 
acquire IPv6 addresses.
