Hi List,

I have a situation where I need to take 3 PVC's that I am getting from a
provider and land one of them on an ATM interface (OC-3) and possibly
cross-connect the others to the second port in the PIC to send to another
router (basically performing an ATM switch functionality). Can this be done
on a "2x OC-3 ATM, SMIR" PIC on a m10i ?? And if so, can someone point me to
some config samples as to how to do this?? I imagine this would be a CCC
on interface, but I am a complete noob when it comes to ATM on the juniper.
Relevent configs of what I need to do are below.

Current Cisco config...

interface ATM2/0
 no ip address
 ip route-cache flow
 load-interval 30
 no atm ilmi-keepalive
!
interface ATM2/0.1 point-to-point   -------------------------->  PVC I wish
to terminate on the first OC-3 Port
 description ***Internet PVC***
 ip address x.x.x.x 255.255.255.252
 pvc 3/101
  protocol ip x.x.x.x broadcast
  ubr 75000
  encapsulation aal5snap
 !
!
interface ATM2/0.2 point-to-point  ---------------------------->  1st PVC
CCC to the second port to connect back to the cisco
 description Customer1 T1 #1
 ip address x.x.x.x 255.255.255.252
 pvc 3/102
  protocol ip x.x.x.x broadcast
  ubr 75000
  encapsulation aal5snap

interface ATM2/0.3 point-to-point  ---------------------------->  2nd PVC
CCC to the second port to connect back to the cisco
 description Customer2 T1 #2
 ip address x.x.x.x 255.255.255.252
 pvc 3/103
  protocol ip x.x.x.x broadcast
  ubr 10000

Thx,
Clue
