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 routers or manually add a route:
To view IPv6 routing entries in Layer 2 system mode:
Click Administration > Management Interface > IPv6 Routes.
-or
To view IPv6 routing entries in Layer 3 system mode:
Click IP Configuration > IPv6 Management and Interfaces > IPv6 Routes.
This page displays the following fields:
•
IPv6 Prefix—IP route prefix for the destination 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.
