Example
This example forwards all traffic for subnet 2001::/64 to the next hop router
2001:DB8:2222:7272::254, using the default metric of 1.

Syntax
show ipv6 route [ipv6-address[/prefix-length] | database | interface [vlan vlan-
id] | local | ospf | static]
ipv6-address - A full IPv6 address including the network prefix and host
address bits.
prefix-length - A decimal value indicating how many contiguous bits (from
the left) of the address comprise the prefix (i.e., the network portion of the
address).
database – All known routes, including inactive routes.
interface – Displays all routes that be accessed through this interface.
local – Displays all entries for destinations attached directly to this router.
ospf – Displays external routes imported from the Open Shortest Path First
(OSPF) protocol into this routing domain.
static – Displays all static entries.
vlan-id - VLAN ID. (Range: 1-4093)

Command Usage
◆ The FIB contains information required to forward IP traffic. It contains the
interface identifier and next hop information for each reachable destination
network prefix based on the IP routing table. When routing or topology
changes occur in the network, the routing table is updated, and those changes
are immediately reflected in the FIB.
The FIB is distinct from the routing table (or, Routing Information Base), which
holds all routing information received from routing peers. The forwarding
information base contains unique paths only. It does not contain any secondary
paths. A FIB entry consists of the minimum amount of information necessary to
make a forwarding decision on a particular packet. The typical components
