Suppose that on a 4.6.2 machine (hostA), I have an interface xl0
with address 10.10.1.2, netmask 255.255.255.0.
On that ethernet, I have a host (hostB) that is set up as 10.10.0.1,
netmask 255.255.255.0. I need to send a packet from hostA to hostB,
and to that effect I would like to set up a static route on hostA
indicating that 10.10.0.1 lives on its xl0 interface.
I tried:
1. route add 10.10.0.1 10.10.1.2 -interface
-> arplookup 10.10.0.1 failed: could not allocate llinfo
arpresolve: can't allocate llinfo for 10.10.0.1rt
2. route add 10.10.0.1 -link xl0 -interface
Interesting netstat -rn output:
10.10.0.1 78.6c.30.0.0.0.0.0.e.fa.ce UHLS 0 0 xl0
but does not work (gets wrong ARP entry:
? (10.10.0.1) at 78:6c:30:00:00:00 on xl0 permanent [ethernet])
3. route add 10.10.0.1 -link hostB-MAC-address -interface
Fails with 'add host 10.10.0.1: gateway 1:2:3:4:5:6: Network is unreachable'
Am I trying to do something impossible, or am I just clueless enough
that I did not find the proper way of cajoling the kernel into
cooperation?
Thomas.
