There's at least two ways to bridge over PPP - one is "classic bridging"
(put the PPP interface into a bridge-group, put the LAN interface in
question into the same bridge group, off you go).  I have no idea how
well that still works, as Cisco might consider it "legacy" and no longer
fully supported.

The other option is ethernet-over-mpls ("ATOM EoMPLS"), which requires
that you turn on MPLS on the PPP interface, and then you can virtually
connect two lan ports left and right to make "a long ethernet cable" -
lab it first, MPLS is a complex technology and has lots of potential
to shoot off your foot (and the rest of the network with it).
