Viewing IPv6 Route Tables

The IPv6 Forwarding Table contains the various routes that have been configured. One of these routes is a
default route (IPv6 address:0) that uses the default router selected from the IPv6 Default Router List to send
packets to destination devices that are not in the same IPv6 subnet as the device. In addition to the default
route, the table also contains dynamic routes that are ICMP redirect routes received from IPv6 routers by
using ICMP redirect messages. This could happen when the default router the device uses is not the router
for traffic to which the IPv6 subnets that the device wants to communicate.
To view IPv6 routes:
STEP 1
This page displays the following fields:
• IPv6 Address—The IPv6 subnet address.
• Prefix Length—IP route prefix length for the destination IPv6 subnet address. It is preceded by a
forward slash.
• Interface—Interface used to forward the packet.
• Next Hop—Address where the packet is forwarded. Typically, this is the address of a neighboring
router. It can be one of the following types.
- Link Local—An IPv6 interface and IPv6 address that uniquely identifies hosts on a single network
link. A link local address has a prefix of FE80, is not routable, and can be used for communication
only on the local network. Only one link local address is supported. If a link local address exists on
the interface, this entry replaces the address in the configuration.
- Global—An IPv6 address that is a global Unicast IPV6 type that is visible and reachable from other
networks.
- Point-to-Point—A Point-to-point tunnel.
• Metric—Value used for comparing this route to other routes with the same destination in the IPv6
router table. All default routes have the same value.
• Lifetime—Time period during which the packet can be sent, and resent, before being deleted.
• Route Type—How the destination is attached, and the method used to obtain the entry. The following
values are:
Local
- —A directly-connected network whose prefix is derived from a manually-configured
device's IPv6 address.
- Dynamic —The destination is an indirectly-attached (remote) IPv6 subnet address. The entry was
obtained dynamically via the ND or ICMP protocol.
