I should have been explicit... When you have point-to-point sub-interfaces, inverse ARP queries are not sent. Replies are sent, but replies are *always* sent.
PPPoFR doesn't have an IP address assigned to FR interface/sub-interface, therefore it never asks for the IP on known DLCIs. -- Marko Milivojevic - CCIE #18427 Senior Technical Instructor - IPexpert FREE CCIE training: http://bit.ly/vLecture Mailto: [email protected] Telephone: +1.810.326.1444 Web: http://www.ipexpert.com/ On Wed, Apr 13, 2011 at 18:57, Carlos Valero <[email protected]> wrote: > > Then using a P-2-P sub-interface would not be the right solution. > > In your previous reply your wrote: > > *> Point-to-point subinterfaces or PPPoFR as possible solutions* > > Since this requirement is that no Inv-ARP is used, *I guess this leaves > PPPoFR as the ONLY alternative, correct?* > > If that's the case, then why is that? > > *How exactly does PPPoFR avoid the use of Inv-ARP?* > > > > --- On *Wed, 4/13/11, Marko Milivojevic <[email protected]>* wrote: > > > From: Marko Milivojevic <[email protected]> > Subject: Re: [OSL | CCIE_RS] Basic Frame Relay Question - Sort of > To: "Samir Idris" <[email protected]> > > Cc: [email protected] > Date: Wednesday, April 13, 2011, 5:46 PM > > On Wed, Apr 13, 2011 at 13:51, Samir Idris > <[email protected]<http://mc/[email protected]>> > wrote: > > Hello Jay, > > > > sub-interfaces do not send out inverse ARP requests, only the physical > > interface does that. > > Samir, > > This is not correct.
