Network Qos Policy (ip-interface type) Functionality
The following behavior is supported with use of network IP interface qos policies for LDP and
RSVP(with FRR/PHP) MPLS LSPs:

LSPs setup using LDP uses a global mpls-lsp-exp-profile-map policy. By default, the
system assigns a default mpls-lsp-exp-profile-map policy. User has an option to change
the global policy to use. A new policy mpls-lsp-exp-profile-map policy allows the user to
assign different profile value for MPLS EXP bits for MPLS packets received over
different IP interface. This is helpful for use with primarily RSVP LSP with FRR 1:1. For
LDP LSPs or when using FRR facility it is recommended to use a single mpls-lsp-exp-
profile-map policy for all IP interfaces.
The new policy separate the profile mapping and FC mapping. The FC to use is always
picked from the network policy. Using the EXP to FC mapping configured in the network
policy. EXP to profile mapping is picked up from the "mpls-lsp-exp-profile" policy
associated with the network qos policy.
Each IP interface can define a unique network policy for it use, each possibly using a
different mapping for MPLS LSP EXP bits to forwarding class (FC). It allows for use of
more than 32 distinct network policies, provided network classification resources are
available for use.
If user receives traffic on RSVP LSP and LDP LSP with the same value in the EXP bits,
the system provides the same QoS treatment. The system always uses the FC and the
meter from the network Qos policy for all MPLS traffic received on an IP interface
irrespective of whether its LDP or RSVP LSP.
