Each row entry represents an interface on this virtual router
that participates in the LDP protocol.
Row entries can be created or deleted via SNMP SET requests.
A row with default attribute values is created by setting
vRtrLdpIfRowStatus to 'createAndGo'. A row entry can be
destroyed by setting vRtrLdpIfRowStatus to 'destroy'. An
attempt to destroy a row will fail if vRtrLdpIfAdminState
is not set to 'outOfService'.
