# Multicast Routing Protocol Test Tools

## Overview:

Multicast routing protocol test tools are designed to support test of multicast routing protocol.These emulate the network environmnet and configuration so as to exchange protocol packet with tested targets.

Packet Generator tools
IGMP tool - mhost
DVMRP tool - dnbr
PIM tool - pimnbr

## System Requirement:

Mhost,dnbr and pimnbr require multicast routing enable kernel. These tools create multicast forwarding cache entry with a empty outgoing interface list when receiving a multicast datagram. So, these tools can detect if tested target forward multicast datagram. (Note that these don't forwarding received multicast data.)

## Supported Platforms:

FreeBSD-2.2.x, BSDI 3.0/3.1, Solaris 2.6
