Re: Virtual-template interface and multilink PPP

In the config you list below though, you're using it to combine two
DLCI's. And without any resultant map-class configuration, since you
enabled traffic-shaping, you are defaulting your shaper to 56k per
physical link. (per DLCI, but you only have one)
