Frame Relay PVC Bundles with QoS Support for IP and MPLSConfiguration Examples for Frame Relay PVC Bundles with QoS Support for IP and MPLSSample Output for the show frame-relay vc-bundle CommandThe following example shows the Frame Relay PVC bundle named “MP-4-dynamic” with PVCprotection applied. Note that in this PVC bundle, DLCI 400 is configured to bump traffic explicitly tothe PVC that handles DSCP level 40, which is DLCI 404. All the other DLCIs are configured for implicitbumping. In addition, all the DLCIs are configured to accept bumped traffic.The asterisk (*) before PVC 4a indicates that this PVC was configured with the precedence othercommand, which means the PVC will handle all levels that are not explicitly configured on other PVCs.In this example all PVCs are up so the values in the “Active level” fields match the values in the “Configlevel” fields. If a PVC goes down and its traffic is bumped, the “Active level” field value for the PVCthat went down is cleared. The “Active level” field values for the PVC that the traffic bumped to will beupdated to include the levels of the PVC that went down.The first three PVCs in the following example make up a protected group. All three of these PVCs mustgo down before the bundle will go down. The last two PVCs are protected PVCs: if either of these PVCsgo down, the bundle will go down.Router# show frame-relay vc-bundle MP-4-dynamicMP-4-dynamic on Serial 1/4.1 - Status: UP Match-type: DSCPName DLCI Config.
