Netgear XCM8806 - 8800 SERIES 6-SLOT CHASSIS SWITCH ユーザーズマニュアル

In IPv4, MAC address resolution is done by ARP. For IPv6, this functionality is handled by the 
Neighbor Discovery Protocol. The router maintains a cache of IPv6 addresses and their 
corresponding MAC addresses and allows the system to respond to requests from other 
nodes for the MAC address of the IPv6 addresses configured on the interfaces. 

Also supported is router discovery—the ability to send out router advertisements that can be 
used by a host to discover the router. The advertisements sent out contain the prefixes and 
configuration parameters that allow the end nodes to auto-configure their addresses. The 
switch also responds to requests from nodes for router advertisements.

The following settings can be configured on an interface to manage router advertisements:

Settings to control the sending of router advertisements over the interface periodically 

and to control responding to router solicitations

The maximum time between sending unsolicited router advertisements

The minimum time between sending unsolicited router advertisements

You can configure the following values, that are advertised by the switch:

Managed address configuration flag 

Other stateful configuration flag 

Link MTU

Retransmit timer

Current hop limit

Default lifetime

Reachable time

Additionally, you can configure the following values for each prefix on the prefix list 
associated with an interface:

Valid lifetime of the prefix

On-link flag

Preferred lifetime of the prefix

Autonomous flag

XCM8800 does not support host processing of neighbor router 

advertisements.

Populating the Routing Table 

The switch maintains an IP routing table for both network routes and host routes. The table is 
populated from the following sources:

Dynamically, by way of routing protocol packets or by Internet Control Message Protocol 

(ICMP) redirects exchanged with other routers
