Function

The display ipv6 fib command displays IPv6 FIB entries on the device.

By default, FIB entries on the main board are displayed.

**Table 1** Description of the **display ipv6 fib** command output
Item	Description
Destination	Indicates the route destination.
PrefixLength	Indicates prefix length contributing network address of the destination.
NextHop	Indicates the next hop to forward the packet to the destination.
Flag	Describes route character, using symbols: S: static U: Up G: gateway H: host B: blackhole D: dynamic
Interface	Indicates the outbound interface that forwards the packet.
Tunnel ID	Indicates the tunnel ID. If the packet is forwarded through MPLS, the tunnel ID should not be 0; if the packet is forwarded through IP, the tunnel ID is 0.
TimeStamp	Indicates the time to generate routes in the FIB.
