OL-7433-09
Purpose
(Optional) Configures Multiprotocol Label Switching (MPLS)
experimental (EXP) levels for a Frame Relay PVC bundle
member. This command configures MPLS EXP-based PVC
selection.
level specifies the MPLS EXP level or levels for a Frame Relay
PVC bundle member. Valid values are from 0 to 7. You can
configure a PVC bundle member with a single MPLS EXP level
(0), multiple individual MPLS EXP levels (0,2,3), a range of
MPLS EXP levels (0-2), multiple ranges of MPLS EXP levels
(0-2,4-5), or a combination of individual levels and level ranges
(0,1,2-4,7).
other specifies that the Frame Relay PVC bundle member
handles all of the remaining MPLS EXP levels that are not
explicitly configured on any other bundle member PVCs.
(Optional) Configures the bumping rules for a Frame Relay PVC
bundle member. The default is implicit bumping.
explicit level specifies the precedence, MPLS experimental
(EXP), or differentiated services code point (DSCP) level to
which traffic on the PVC is bumped if the PVC goes down. You
can specify only one service level for bumping. For PVC bundles
that use precedence or MPLS EXP mapping, valid values for
level are from 0 to 7. For PVC bundles that use DSCP mapping,
valid values are from 0 to 63.
When the PVC goes down, the router directs the traffic to
Note
a PVC mapped with the service level you configure in
explicit level.
implicit applies the implicit bumping rule, which is the default,
to a single bundle member. The implicit bumping rule stipulates
that bumped traffic is to be carried by a PVC that has the lower
precedence level.
traffic specifies that the PVC accepts bumped traffic. By default,
a PVC accepts bumped traffic.
To configure a PVC to reject bumped traffic from another
Note
bundle member, enter the no bump traffic command.
(Optional) Specifies the protection rule for a PVC bundle
member. By default, the PVC bundle member is not protected.
group configures the PVC bundle member as part of a collection
of protected PVCs within the PVC bundle and specifies that the
PVC bundle goes down when the last PVC in the protected group
goes down.
vc configures the PVC member as individually protected and
specifies that the PVC bundle goes down whenever the PVC goes
down.
(Optional) Enables Inverse ARP for the PVC bundle member. By
default, Inverse ARP traffic uses the PVC configured for
precedence level 6 or DSCP level 63.
