| Description | This value supplements the value in the object
mplsTunnelRole in MPLS-TE-STD-MIB that indicates the role
of this LSR in the tunnel represented by this entry in
cmplsTeP2mpTunnelTable.
mplsTunnelRole may take any of the values:
head(1),
transit(2),
tail(3),
headTail(4)
If this LSR is an ingress and there is exactly one
out-segment, mplsTunnelRole should contain the value
head(1), and cmplsTeP2mpTunnelBranchRole should have the
value notBranch(1).
If this LSR is an ingress with more than one out segment,
mplsTunnelRole should contain the value head(1), and
cmplsTeP2mpTunnelBranchRole should have the value branch(2).
If this LSR is an ingress, an egress, and there is one or
more out-segments, mplsTunnelRole should contain the value
headTail(4), and cmplsTeP2mpTunnelBranchRole should have the
value bud(3).
If this LSR is a transit with exactly one out-segment,
mplsTunnelRole should contain the value transit(2), and
cmplsTeP2mpTunnelBranchRole should have the value
notBranch(1).
If this LSR is a transit with more than one out-segment,
mplsTunnelRole should contain the value transit(2), and
cmplsTeP2mpTunnelBranchRole should have the value branch(2).
If this LSR is a transit with one or more out-segments and
is also an egress, mplsTunnelRole should contain the value
transit(2), and cmplsTeP2mpTunnelBranchRole should have the
value bud(3).
If this LSR is an egress with no out-segment and is not the
ingress, mplsTunnelRole should contain the value tail(3),
and cmplsTeP2mpTunnelBranchRole should have the value
notBranch(1).
If this LSR is an egress and has one or more out-segments,
mplsTunnelRole should contain the value transit(1), and
cmplsTeP2mpTunnelBranchRole should have the value bud(3). |
