No.

There are two possibilities to handle the routing via multiple
interfaces, whether they be PPP or some other IP interface.

1.  One interface goes to the Internet, and the other interfaces are
    relatively local.  This is the usual case.  You specify the
    networks that are behind the "local" interfaces, and put the
    default route on the Internet gateway.

2.  You have two Internet interfaces (for example, to two ISPs).  In
    this case, you should run some routing protocol, preferably OSPF.
    Look at the gated port for more information.
