SRTCONFIG(1)            NetBSD General Commands Manual            SRTCONFIG(1)


NAME

     srtconfig -- configure srt interfaces


SYNOPSIS

     srtconfig srtX
     srtconfig srtX N
     srtconfig srtX del N
     srtconfig srtX add srcaddr mask dstif dstaddr
     srtconfig srtX set N srcaddr mask dstif dstaddr


DESCRIPTION

     srtconfig configures, or queries the configuration of, srt(4) interfaces.
     An srt(4) interface parcels packets out to other interfaces based on
     their source addresses (the normal routing mechanisms handle routing
     decisions based on destination addresses).  An interface may have any
     number of routing choices; they are examined in order until one matching
     the packet is found.  The packet is sent to the corresponding interface.
     (Any interface, even another srt interface, may be specified; if the con-
     figurations collaborate to cause a packet to loop forever, the system
     will lock up or crash.)

     When run with only one argument, srtconfig prints the settings for the
     specified interface.

     When run with two arguments, srtconfig prints the settings for the rout-
     ing choice whose number is given as the second argument.

     The form with `del' deletes a routing choice, identified by its number.
     Other choices with higher numbers, if any, will be renumbered accord-
     ingly.

     The `add' form adds a choice; the other arguments describe it, and are
     documented below.  The new choice is added at the end of the list.

     The `set' form replaces an existing choice, given its number.  The other
     arguments describe the new choice which is to replace whatever currently
     exists at the given number N.

     A choice is described by four pieces of information: a source address and
     mask, which are used to determine which choice an outgoing packet uses, a
     destination interface, and a destination address for the new interface.
     The source address and mask are specified like any Internet addresses
     (for convenience, the mask may instead be specified as a `/' followed by
     a small integer, CIDR-style; note that in this case the mask must still
     be a separate argument; it cannot be appended to the end of the source
     address argument).

     Each srt interface also has ordinary source and destination addresses
     which are set with ifconfig(8) like any other interface; these should not
     be confused with any of the above.
