An LER allows the operator to map traffic to a Diff-Serv 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 Diff-Serv 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
