Danny,
yes i agree its the ppp that installs the host route...but it doesnt cause
the ISDN link to flap.....its the Classful DV protocol which causes the link
to flap.....for the same reasons that u have mentioned in the previous post.
I have posted a pdf file on this in the group.Check it out and lemme know.
cheers,
sumit.
