<P><FONT size=2><FONT face=Arial>Hi
Mark,<BR> You cannot use OSPF over PPP
links if the IP address is negotiated for any side. This is b'cos PPP doesn't
have any option to negotiate the mask information and hence will always use a
/32 bit mask when IP address is
negotiated.<BR> As there cannot be
more than 1 host on a /32 network, OSPF will always complain that the remote
peer is not in the same subnet. Remember that OSPF needs both the ends in the
same network to form neighbour
relationship.<BR><BR> I don't think
there is any possible relation;<BR><FONT
color=#0000ff> I wanted to say "there
is any possible solution".
:-)</FONT><BR><BR> The workaround
would be to use static IPs on both sides or use "ip
innumbered"<BR><BR>Regards<BR>Prem</FONT><BR><BR><BR>-- If you live each day as
if it was your last, someday you'll certainly be right.<BR><BR>-----Original

over pppoe link<BR><BR>yes that fixed that problem. The two client router and
the lns see hello packets form each other. The lns goes into int mode. The
client complaints "Rcv pkt from xxx.x.137.65, Dialer2, area 0.0.0.0 : src not on
the same network"<BR><BR>As the dialer 2 interface has a /32 ip and the
interface bound to the virtual-template can't be part of that /32 network I am
not sure what the solution to this would be.<BR><BR><BR>----- Original Message

Depending on your IOS version, you could use the "ip ospf area<BR>>>>

Radius/lcp:interface-config) and use "network
