[Xorp-users] running multiple instances of XORP on the same host

For the time being you should set the XORP_FINDER_SERVER_PORT
environmental variable before starting XORP to match that
port. E.g.:

setenv XORP_FINDER_SERVER_PORT 20000

I believe that if you set this variable, then you don't need to use
the "-p" flag.

This is not (yet) in the documentation, because we haven't finalized
the solution for running multiple XORP instances.

BTW, have in mind that you won't be able to run multiple instances
if 2+ instances try to do multicast routing. The UNIX kernel allows
only one multicast routing socket.
