Viewing IPv6 Route Tables
The IPv6 Routes Table Page displays the IPv6 Routes Table. The table contains a
single 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 switch. In addition to the default route, the table also
contains dynamic routes which are ICMP redirect routes received from IPv6
routers by using ICMP redirect messages. This could happen when the default
router the switch uses is not the router for traffic to the IPv6 subnets that the
switch wants to communicate to.
To view IPv6 routing entries, click Administration > Management Interface >
IPv6 Routes.
The
IPv6 Routes Table Page opens.
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. This must be a link local address.
• 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.
• Life Time—Time period that 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 —The manually configured switch IPv6 address.
-
Dynamic —The destination is indirectly attached IPv6 subnet address.
The entry was obtained dynamically via the ICMP protocol.
