The value of vRtrMplsLspPathOperAdminGrExcld is a bit-map
which specifies a list of admin groups excluded by the
currently operational LSP path.
When make-before-break functionality for the LSP is enabled and if the
list of excluded admin groups is changed at either LSP or LSP path
level, the resources allocated to the existing LSP paths will not be
released until a new path with the new settings has been established.
While a new path is being signaled, the administrative value and the
operational values of the path may differ. The value of either
vRtrMplsLspAdminGroupExclude or vRtrMplsLspPathAdminGroupExclude
specifies the exclude admin groups bit-map for the new LSP path trying
to be established whereas the value of vRtrMplsLspPathOperAdminGrExcld
specifies the exclude admin groups bit-map for the existing LSP path.
