IP Service Provisioning
Configuration for LSC 1 and LSC 2 Portions of the Cisco IGX 8410, 8420, and 8430
Before configuring the routers for the label switch (MPLS) controlling function, it is necessary to
perform the initial router configuration. As part of this configuration, it is necessary to configure and
enable the ATM adapter interface.
After configuring the ATM adapter interface, the extended ATM interface can be set up for label
switching. The IGX ports can be configured by the router as extended ATM ports of the physical router
ATM interface, according to the following procedures for LSC1 and LSC2.
Configuration for LSC1 Portion of ATM-LSR-1
Proceed with configuration as follows:
Command Description
Before you begin
Step 1
Router LSC1(config)# ip routing
Enables IP routing protocol.
Step 2
Router LSC1(config)# ip cef
Enables Cisco express forwarding protocol.
Step 3
Router LSC1(config)# interface ATM3/0
Enables physical interface link to IGX.
Step 4
Router LSC1(config-if)# no ip address
Step 5
Router LSC1(config-if)# label-control-protocol vsi
[controller ID}
Enables router ATM port ATM3/0 as MPLS
controller. Controller ID default is 1, optional values
up to 32 for IGX.
Setting up the interslave control link
Step 6
Router LSC1(config-if)# interface XmplsATM33
Interslave link on 3.3 port of IGX (port 3 on UXM in
slot 3). This is an extended port of the router
ATM3/0 vsi 0x00010300 port.
Step 7
Router LSC1(config-if)# extended-port ATM3/0 vsi
0x00010300
Binds extended port XmplsATM13 to IGX slave
port 1.3.
Step 8
Router LSC1(config-if)# ip address 142.4.133.13
255.255.0.0
Assigns ip address to XmplsATM13.
Step 9
Router LSC1(config-if)# mpls ip
Enables MPLS for xtag interface XmplsATM13.
Setting up interslave port
Step 10
Router LSC1(config-if)# interface XmplsATM42
Interslave link on port 4.2 on the IGX (port 2 on the
UXM in slot 4). This is an extended port of the
router ATM3/0 vsi 0x00010300 port.
Step 11
Router LSC1(config-if)# extended-port ATM3/0 vsi 5.2
Binds extended port XmplsATM52 to IGX slave
port 5.2
Step 12
Router LSC1(config-if)# ip address 142.6.133.22
255.255.0.0
Assigns an IP address to XmplsATM52.
Step 13
Router LSC1(config-if)# mpls ip
Enables MPLS for xtag interface XmplsATM52.
Step 14
Router LSC1 (config-if)# exit
Configuring routing protocol
Configure Open Shortest Path First (OSPF) Routing
Protocol or Enhanced Interior Gateway Routing
Protocol (EIGRP).
