130 
131  The use-case is that, for some unspecified reason, the control plane
132  has a different set of neighbours it than VPP
133  currently has. The CP would thus like to 'replace' VPP's set
134  only by specifying what the new set shall be, i.e. it is not
135  going to delete anything that already exists, rather, it wants any
136  unspecified neighbors deleted implicitly.
137  The CP declares the start of this procedure with this replace_begin
138  API Call, and when it has populated all neighbours it wants, it calls
139  the below replace_end API. From this point on it is of course free
140  to add and delete neighbours as usual.
141  The underlying mechanism by which VPP implements this replace is
142  intentionally left unspecified.
