Issue Description
Q:
What is the meaning of "0" in X.X.X.X:0 of display mpls ldp session?
Alarm Information
Null 
Handling Process
A:
We often read "X.X.X.X:0" and "X.X.X.X:2" after entering display mpls ldp session, for example, 
<Quidway>disp mpls ldp sess
   Local LDP ID: 61.189.153.49:0;   Peer LDP ID: 61.189.165.6:0
   TCP Connection: 61.189.153.49 <- 61.189.165.146
   Session State: Operational
   Session Role: Passive
…………
Here "0" and "2" of "X.X.X.X:0" and "X.X.X.X:2" are:
0: LDP Allocation tag is based on platform.
Non-0: LDP Allocation tag is based on interface.
Tag based on platform is to realize LSP load balance.
VRP3 platform is based on interface to have tag allocation. VRP5  is changed as tage allocation based on platform.
