Read the man page for the PPP daemon (on my box, it's pppd(8)), paying 
special attention to the section titled "SCRIPTS".  It may contain some 

I use the "ipparam" option in the /etc/ppp/peers/* files, to do pretty 
much what you're doing.  This is supposedly [see next paragraph] passed 
to your script by pppd as the sixth parameter on the command line.  pppd 
also sends the authenticated peer's name as "PEERNAME" (but only if 
authentication is performed, and completed successfully).

I've had problems with $6 not being set to the value of the "ipparam" 
option in the ip-down script, so I end up resorting to using the 
PEERNAME environment variable - which probably won't do what you want it 
to do if those two connections are to the same peer.  I should consider 
using the "linkname" option, I guess.

One day, I'll get around to figuring out why ipparam isn't passed to 
ip-down by pppd (or correcting the man page to conform with the code).
