Cisco Small Business 200 Series Smart Switch Administration Guide
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.
IPv6 Routes Table Page
The
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.
The switch maintains an ARP (Address Resolution Protocol) Table for all the known
devices that reside in its directly connected IP subnets. A directly connected IP
subnet is the subnet that a IPv4 interface of the switch is connected to. When the
switch needs to send/route a packet to a local device, it searches the ARP Table to
opens.
