Hi Dave,

Just labbed Amit's suggestion up.  Note in config below that both VTs have the
same IP address.  It is a hack, but it works.  Not sure if this is the
solution for your lab, but it is one solution.


interface Serial0/0
 description Determine Frame Interfaces based on requirement
 no ip address
 encapsulation frame-relay
 frame-relay interface-dlci 102 ppp Virtual-Template102
 frame-relay interface-dlci 103 ppp Virtual-Template103
!
interface Virtual-Template102
 ip address 172.16.123.1 255.255.255.0
!
interface Virtual-Template103
 ip address 172.16.123.1 255.255.255.0

  That requires that you use ppp, correct?  These are on the same subnet and I
only have a single ip address on the multipoint at R2.

  Dave,



  Amit's solution looks like the ticket.  If you can create two Virtual
Templates, each associated with a different PVC, then you will not need
mapping, since the VT is point-to-point.  Addressing two VTs with the same
subnet/IP could be an issue, though.

    Does that require that you use PPP.  How does this solve the mapping
    issue?

    If you are using two different subnets on both subints then you can use
    virtual templates and bind each VT to frame-relay interface-dlci
    command.
