<H2>DESCRIPTION</H2>
|
|
|
|
avahi-autoipd implements IPv4LL, "Dynamic Configuration of IPv4 Link-Local Addresses" (IETF RFC3927), a protocol for automatic IP address configuration from the link-local 169.254.0.0/16 range without the need for a central server. It is primarily intended to be used in ad-hoc networks which lack a DHCP server.
|
|
<P>
|
|
IPv4LL is part of the Zeroconf stack.
|
|
<P>
|
|
avahi-autoipd can be used as stand-alone address allocator or as plugin for a DHCP client such as ISC's dhclient, where it can be used as fallback solution if no DHCP server is found.
|
|
<P>
|
|
To allow communication between hosts that have only an IPv4LL address assigned and hosts that only have a routable IP address assigned you may add the following routes to both network configurations:
|
|
<P>
|
|
<B>route add -net 169.254.0.0 netmask 255.255.0.0 dev eth0 metric 99</B>
|
|
<P>
|
|
<B>route add default dev eth0 metric 99</B>
|
|
<P>
|
