How much do you need to do? I did this just yesterday to test some
hardware:
ifconfig hdlc0 10.39.58.58 netmask 255.255.0.0 broadcast
10.39.255.255
ifconfig hdlc1 10.39.58.59 netmask 255.255.0.0 broadcast
10.39.255.255
route add 1.2.3.4 dev hdlc0
ping 1.2.3.4 &
tcpdump -i hdlc1
There were no responses, of course, but hdlc1 did receive the requests.
