    description
      "This module describes a YANG model for BGP protocol
configuration.It is a limited subset of all of the configuration
parameters available in the variety of vendor implementations,
hence it is expected that it would be augmented with vendor-
specific configuration data as needed. Additional modules or
submodules to handle other aspects of BGP configuration,
including policy, VRFs, VPNs, and additional address families
are also expected.

This model supports the following BGP configuration level
hierarchy:

 BGP
   |
   +-> [ global BGP configuration ]
     +-> AFI / SAFI global
   +-> peer group
     +-> [ peer group config ]
     +-> AFI / SAFI [ per-AFI overrides ]
   +-> neighbor
     +-> [ neighbor config ]
     +-> [ optional pointer to peer-group ]
     +-> AFI / SAFI [ per-AFI overrides ]

Most BGP features can be configured at multiple levels in the BGP
configuration level hierarchy. The common inheritance model allows
the more specific configuration (e.g. neighbor) to inherit from or
override the less specific configuration (e.g. global).
Leaf present at one level overrides leafs present at higher levels,
whereas leaf not present inherits its value from the leaf present
at the next higher level in the hierarchy.";
