NDPPD.CONF(5) NDP Proxy Daemon Manual NDPPD.CONF(5)

NAME

ndppd.conf - configuration file for ndppd

DESCRIPTION

The syntax is as follows:

proxy eth0 {

rule 1234:5678::/96 {
} }

The configuration file must contain one or more proxy sections, and each of these section must contain one or more rule sections.

The ndppd daemon listens on the interface specified as an argument to the proxy section. Once a Neighbor Solicitation message arrives, it will try to match the target address against the address specified as the argument of the rule section.

OPTIONS

Adds a proxy and binds it to the specified interface. See below for information about proxy options.

PROXY OPTIONS

Adds a rule with the specified address to the proxy. It may be a an IP such as 1234::1 or a subnet such as 1111::/96. See below for information about rule options.
Controls how long ndppd will cache an entry. This is in milliseconds, and the default value is 30000 (30 seconds).
Controls whether ndppd will automatically create host entries in the routing tables when ndppd receives Neighbor Advertisements on a listening interface. The default value is no.
Controls whether ndppd will put the proxy listening interface into promiscuous mode and hence will react to inbound and outbound NDP commands. This is required for machines behind the gateway to talk to each other in more complex topology scenarios. The the default value is no.
Controls how long ndppd will wait for a Neighbor Advertisement message after forwarding a Neighbor Solicitation message according to the rule. This is in milliseconds, and the default value is 500 (.5 second).
Controls if ndppd should send the router bit when sending Neighbor Advertisement messages. The default value here is yes.

RULE OPTIONS

Specify a method here. See below.

METHOD

One of the following options must be specified in the rule section. All of these are mutually exclusive options, and cannot be combined.

Specify which interface the Neighbor Solicitation message will be sent out through.
(NEW) If this option is specified ndppd will attempt to detect which interface to use in order to forward Neighbor Solicitation Messages, by reading the routing table /proc/net/ipv6_route.
(NEW) This option tells ndppd that it should immediately respond to a Neighbor Solicitation Message without querying an internal interface. Note that it's recommended that you use this option sparingly, and with as high prefix length as possible. This is to make sure upstream routers are not polluted with spurious neighbor entries.

If no rule option has been specified, it will default to static in order to be compatible with 0.2.1. This will, however, produce a warning, and most likely not work in future versions of ndppd.
