[cisco-bba] PPPoE with Routed Subnet<BR></FONT><BR></DIV>
<DIV></DIV>
<DIV>Hi Andy,</DIV>
<DIV> </DIV>
<DIV>The configuration you have suggested would be a typical PPPoE setup, but
I'm faced with a situation where the IP assignment is something like:</DIV>
<DIV> </DIV>
<DIV>Static IP assigned via Service Provider: <A
href="http://203.40.50.61/32">203.40.50.61/32</A></DIV>
<DIV>Routed Subnet: <A href="http://203.40.50.60/29">203.40.50.60/29</A></DIV>
<DIV> </DIV>
<DIV>RADIUS would probably have a Framed-Route attribute of something like
Framed-Route="<A href="http://203.40.50.60/29">203.40.50.60/29</A> 203.40.50.61
1"</DIV>
<DIV> </DIV>
<DIV>Meaning the the dialer interface (or bridged interface or whatever that
interface might be) will have .61 and other usable IPs in that subnet will be
used for hosts behind that router.<BR></DIV>
<DIV>Any ideas?</DIV>
<DIV> </DIV>
<DIV>Thanks again.</DIV>
<DIV> </DIV>
<DIV>cheers,</DIV>
<DIV>Patrick<BR></DIV>
