An LER allows the operator to map traffic to a DiffServ LSP using one of the following methods:
explicit RSVP SDP configuration of a VLL, VPLS, or VPRN service
class-based forwarding in an RSVP SDP. The operator can enable the checking by RSVP that a Forwarding Class (FC) mapping to an LSP under the SDP configuration is compatible with the DiffServ Class Type (CT) configuration for this LSP.
the auto-bind-tunnel RSVP-TE option in a VPRN service
static routes with indirect next-hop being an RSVP LSP name
