IPv6 Routes
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:
Click IP Configuration > IPv6 Management and Interfaces > IPv6 Routes.
This page displays the following fields:
• IPv6 Prefix—IP route address 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.
• Outgoing Interface—Interface used to forward the packet.
• Next Hop—Type of address to which 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:
- S (Static) —Entry was manually configured by a user.
- I (ICMP Redirect)—Entry is an ICMP redirect dynamic route received from an IPv6 router by using ICMP redirect messages.
- ND (Router Advertisement)—Entry is taken from a router advertisement message.
