Explicit routes between endpoints
In the case where there are multiple LSPs between the two PEs, it may be 
desirable to be able to select which LSP is used to route a VC. For 
example, multiple traffic engineering paths may be created in order to 
carry various grades of traffic. The first implementation will allow the 
service provider to select more than one LSP to a destination router, but 
the implementation may not fully interoperable with other vendors 
implementation. The reason for this initially is the lack of clear 
guidelines and procedures in [1] which explains how to set up the LDP 
session or how many should be setup. The Cisco implementation will employ 
multiple LDP targetted discoveries for to each destination address 
specified. A Cisco router will respond by re-using an existing targeted 
session if one exists. Other vendors routers may not be capable of this.
