# Simple demo script for the new APIs to support multi-interface for
# wireless node.
#
# Define options
# Please note:
# 1. you can still specify "channelType" in node-config right now:
# set val(chan)           Channel/WirelessChannel
# $ns_ node-config ...
#        -channelType $val(chan)
#                  ...
# But we recommend you to use node-config in the way shown in this script
# for your future simulations.
#
# 2. Because the ad-hoc routing agents do not support multiple interfaces
#    currently, this script can't generate anything interesting if you config
#    the interfaces of node 1 and 2 on different channels
