They're virtual addresses so they certainly CAN do that. It's a little
strange from a design standpoint though. What I would venture to say in
this regard is that while your router (R2?) is needing to have the SAME
SINGLE IP address all along, perhaps later on you'll want to have separate
QoS or traffic-shaping for one multilink versus another.
Personally, I would have put that IP address onto a loopback and just use
"ip unnumbered loopback1" or something like that.

Subject: Re: Multilink interfaces with the same IP address
OK.... I accidently pasted the wrong example before -sorry. Here's the
proper example:
interface Multilink1
ip address 143.43.65.2 255.255.255.0
ppp multilink
ppp multilink group 1
!
interface Multilink2
ip address 143.43.65.2 255.255.255.0
ppp multilink
ppp multilink group 2
!
interface Serial0/1/0
no ip address
encapsulation frame-relay
frame-relay traffic-shaping
frame-relay interface-dlci 205 ppp Virtual-Template1
frame-relay interface-dlci 206 ppp Virtual-Template2
frame-relay interface-dlci 215 ppp Virtual-Template1
frame-relay interface-dlci 216 ppp Virtual-Template2
frame-relay interface-dlci 225 ppp Virtual-Template1
frame-relay interface-dlci 226 ppp Virtual-Template2!
