The value of vRtrMplsP2mpInstAdminGrpExclude is a bit-map that
specifies a list of admin groups that should be excluded when
this P2MP LSP is setup. If bit 'n' is set, then the admin group
with value 'n' is excluded for this P2MP LSP. This implies that
each link that this P2MP LSP goes through must not be associated
with any of the admin groups in the exclude list.
By default, no admin groups are in the exclude list.
