also, in global config: multilink virtual-template1
see: http://www.cisco.com/warp/public/131/7.html

"show ppp multilink" on the router. make sure you have multiple connections
and multilink authorized on radius.

theoretically...yes

the amount of cpu increase depends on how many members you have in the
bundle, ie how many times you are fragmenting the packet. if you have a ton
of members in the bundle you may want to turn of fragmentation. you may
also want to take a look at this:

anyone that works with unnumbered interfaces i guess. what do you currently
use in your network?

> Here is my current configuration :

> ppp authentication pap

add "ppp mult" and make sure "ppp mult" is configured on whichever physical
interfaces that you want this to work with.

if it doesn't work as expected get:
debug ppp nego
debug ppp mult event
debug aaa author
(bounce the physical interfaces if you can. and after everything comes up:)
sh int
sh ppp mult
sh user
