Detailed Description

This daemon can be configured to "own" several IPs for which it will send out ARP replies when receiving ARP requests.

ARPd (VrrpInterface& vif)

ARPd

Parameters:

vif

the VRRP interface on which the daemon runs.

~ARPd ()

~ARPd

void clear ()

clear

Remove all configured IPs.

void insert (const IPv4& ip)

insert

Add an IP for which ARP replies should be sent.

Parameters:

ip	the IP to add.

void stop ()

stop

Stop the daemon.

void start ()

start

Start the daemon.

void ips_updated ()

ips_updated

Using this method the caller notifies ARPd that it has finished manipulating the IP addresses. This way one can clear and add IPs one by one without causing ARPd to stop (if IPs are cleared) and resume if IPs are added.

void recv (const Mac& src, const PAYLOAD& payload)

recv

This method notifies the reception of an ARP packet.

Parameters:

mac	the source MAC address of the packet.
payload	the ARP header and data.

void set_mac (const Mac& mac)

set_mac

Sets the MAC address of the ARP daemon, used when generating replies.

Parameters:

mac

the MAC address.
