John,
By default, links that use the same username are bundled together into the
same MP virtual connection.
r4#sho ppp multilink
Virtual-Access2, bundle name is r6
Bundle up for 4d12h
0 lost fragments, 0 reordered, 0 unassigned
0 discarded, 0 lost received, 1/255 load
0x5 received sequence, 0x5 sent sequence
Member links: 2 (max not set, min not set)
Vi1, since 3d12h, no frags rcvd, 375000 weight, 1496 frag size !the
frame PVC
Se0/1, since 3d12h, no frags rcvd, 5790 weight, 1496 frag size !S0/1 ppp
int
To get this to "work" you would need to create a 2 PPPoFR links on the hub,
one to each spoke, and then you're right back where you started with the
PVC's :)
Check out the Multilink section here:

&s=Implementation_and_Configuration#Samples_and_Tips
And the PPPoFR section here:

Hope this is helpful. I have been trying to increase my knowledge on this
subject over the last few days, so am by no means an expert. Feel free to
challenge me.
Rich

i'm not sure i follow your config.....
i don't see where you have bound 2 interface to 1 virtual-template.
when you issue the command "frame-relay interface-dlci 304 ppp
Virtual-Template1" does this mean that the other end must be running ppp
over frame relay as well? (lightbulb goes on....!) so i'd have to create a
virtual-template on both the the hub and spokes for this to work....eh?

I've been messing with this a bit. PPP (MLPPP) assumes 2 endpoints, and
fragments packets between the physical links in the ML Bundle, so if DLCI
304 and 305 both terminated to the same remote router it will work.
Here's a config snippet with MLPPP working over one PPP connection and one
frame connection (between the same 2 routers).
!
interface Serial0/0.1 point-to-point
frame-relay interface-dlci 406 ppp Virtual-Template1
class SOMECLASS
!
interface Serial0/1
no ip address
encapsulation ppp
ppp authentication chap
ppp multilink
!
interface Virtual-Template1
ip unnumbered Loopback1
service-policy output SOMEPOLICY
ppp multilink
ppp multilink interleave

Subject: virtual-template question
if you have 3 routers in a hub and spoke topology, and on the hub you create
two p2p interfaces w/ dlci's, can you bind those p2p interfaces into a
virtual-template which acts like both p2p's are actually 1 multipoint
interface? i tried it and i can't seem to get it to work so i'm thinking
that perhaps there is some limitation on this:<??>
HUB
interface Serial1/0.34 point-to-point
frame-relay interface-dlci 304 ppp Virtual-Template1
!
interface Serial1/0.35 point-to-point
frame-relay interface-dlci 305 ppp Virtual-Template1
interface Virtual-Template1
ip address 164.1.0.3 255.255.255.0
