IPv6 Neighbor Discovery of MTU Packets

You can set the MTU advertised through the RA packets to incoming routers, without altering the actual

MTU setting on the interface.

The ipv6 nd mtu command sets the value advertised to routers. It does not set the actual MTU rate. For

example, if you set ipv6 nd mtu to 1280, the interface still passes 1500-byte packets, if that is what is

set with the mtu command.

This section describes how to configure the IPv6 Recursive DNS Server.

This sections contains the following configuration task list for IPv6 RDNSS:

Debugging IPv6 RDNSS Information Sent to the Host

Displaying IPv6 RDNSS Information

Configuring the IPv6 Recursive DNS Server

You can configure up to four Recursive DNS Server (RDNSS) addresses to be distributed via IPv6 router

advertisements to an IPv6 device, using the ipv6 nd dns-server ipv6-RDNSS-address {lifetime

| infinite} command in INTERFACE CONFIG mode.

The lifetime parameter configures the amount of time the IPv6 host can use the IPv6 RDNSS address for

name resolution. The lifetime range is 0 to 4294967295 seconds. When the maximum lifetime value,

4294967295, or the infinite keyword is specified, the lifetime to use the RDNSS address does not

expire. A value of 0 indicates to the host that the RDNSS address should not be used. You must specify a

lifetime using the lifetime or infinite parameter.
