| Description | A row in this table represents a link between PW VCs (that
require MPLS tunnels) and MPLS tunnel for packets arriving
from the PSN.
This table is indexed by the set of indexes used to
identify the VC - cpwVcIndex and an additional
index enabling multiple rows for the same VC index.
Note that the first entry for each VC can be indexed by
cpwVcMplsOutboundIndex equal zero without a need for
retrieval of cpwVcMplsInboundIndexNext.
An entry is created in this table either automatically by
the local agent or created manually by the operator in
cases that strict mode is required.
Note that the control messages contain VC ID and VC type,
which together with the remote IP address identify the
cpwVcIndex in the local node.
This table points to the appropriate MPLS MIB. In the case
of MPLS-TE, the 4 variables relevant to the indexing of a
TE MPLS tunnel are set as in Srinivasan, et al, .
In case of non-TE MPLS tunnel (an outer tunnel label
assigned by LDP or manually) the table points to the XC
entry in the MPLS-LSR-MIB as in Srinivasan, et al, .
Each VC may have multiple rows in this tables if protection
is available at the outer tunnel level, each row may be of
different type except for VC only, on which only rows with
ifIndex of the port are allowed. |
