| Description | The mplsTunnelARHopTable is used to indicate the
hops, strict or loose, for an MPLS tunnel defined in
mplsTunnelTable, as reported by the MPLS signaling
protocol, for the outgoing direction of the tunnel.
Each row in this table is indexed primarily by the
same indices, mplsTunnelIndex and
mplsTunnelInstance, as the row of the corresponding
tunnel in mplsTunnelTable. Each row also has a
third index mplsTunnelARHopIndex, corresponding to
the next hop that this row corresponds to. The
first row in the table is the first hop after the
origination point of the tunnel. In case we want to
specify a particular interface on the originating
LSR of an outgoing tunnel by which we want packets
to exit the LSR, we specify this as the first hop
for this tunnel in mplsTunnelARHopTable.
Please note that since the information necessary to
build entries within this table are not provided by
some MPLS signaling protocols, implementation of
this table is optional. Furthermore, since the
information in this table is actually provided by
the MPLS signaling protocol after the path has been
set-up, the entries in this table are provided only
for observation, and hence, all variables in this
table are accessible exclusively as read-only. |
