Summary of MPLS Configuration Commands

Now that we have configured all the different platforms, we can create a synopsis of all the configuration commands for them. We will follow the "Generic Configuration Model" section and identify all the required steps to complete each task.

Generic LSR Bringup

Table 6-3 enumerates all the required commands to finish each step in the LSR bringup. Refer back to Figure 6-2 to recall each task. The numbers in parentheses mean the following:

(1) In the BPX or IGX switch command-line interface (CLI)

(2) In the RPM-PR CLI

(3) In the PXM-45 CLI

(4) In the LSC CLI

Table 6-3. Summary of ATM MPLS LSR Configuration

Task Number	BPX-8650	IGX-8400		MGX-8850
		URM LSC	External LSC
1	(1) uptrk cnfrsrc	(1) addport upport cnfrsrc	(1) upln addport upport cnfrsrc	(2) (config-if)#switch partition vcc
2	(1) addshelf	(1) addctrlr		(3) addcontroller
3	(4) (config-if)#label-control-protocol vsi
4	(4) (config)#ip cef (config)#mpls label protocol ldp (config)#mpls ldp router-id loopback 0

In addition to the commands listed in Table 6-3, we still need to configure the routing portion in Step 4, which depends on the IGP used.

Generic eLSR Bringup

Table 6-4 is a review of the entire configuration command set needed to bring up an ATM MPLS eLSR in the different platforms. Refer to Figure 6-3 to recall each task. The numbers in parentheses mean the following:

(1) In the BPX or IGX switch CLI

(2) In the RPM-PR CLI

(3) In the AXSM CLI

(4) In the LSC CLI

(5) In the eLSR CLI

Table 6-4. Summary of ATM MPLS eLSR Configuration

Task Number	BPX-8650	IGX-8400		MGX-8850
		URM eLSR	External eLSR	RPM eLSR	External eLSR
1	(1) upln addport upport cnfrsrc	(1) addport upport cnfrsrc	(1) upln addport upport cnfrsrc	(2) (config-if)#switch partition vcc	(3) cnfcdsct upln addport addpart
2	(4) (config)#interface xtagatm
3	(4) (config-if)#ip unnumbered loopback 0 (config-if)#mpls ip (config-if)#extended-port
4	(5) (config)#ip cef (config)#mpls label protocol ldp (config)#mpls ldp router-id loopback 0
5	(5) (config)#interface <atm|switch> X.1 mpls
6	(5) (config-subif)#ip unnumbered loopback 0 (config-subif)#mpls ip
7	(5) (config-subif)#mpls atm vp-tunnel <VPI> [vci-range<VCIRange>] (config-subif)#mpls atm vpi <minVPI>-<maxVPI> [vci-range<VCIRange>]
8	(4) and (5) (config-subif)#mpls atm control-vc <VPI> <VCI>

Additionally, a routing protocol needs to be configured in Step 4.
