Re: Reception of RSVP packets at intermediate node

["Raju Venkatraman" <raju_vvs@hotmail.com>]

Hi,

Can someone point me to these SunOS patches that were required to fix the 
problem of RSVP packets interception and reception at intermedite nodes. Are 
they publically available at some site?????

How does the other protable implementations take care of it when they run 
over SunOS/Solaris??? Which socket option they use?

Any help shall be greatly appreciated.
Regards.
Raju
