EoMPLS Configuration on PE-CLE SPR Interface
EoMPLS Configuration on PE-CLE SPR Interface
To enable the RPR to act as an access ring for the MPLS cloud, you must provision the SPR interface on
the same ML-Series card that hosts the EoMPLS PE-CLE FastEthernet or GigabitEthernet interfaces.
Interface SPR 1 on card A and card C plays this role in
Figure 18-2 on page 18-10 .
Note SPR subinterfaces do not support MPLS.
To provision the SPR interface for MPLS, perform the following procedure, beginning in global
configuration mode:
Bridge Group Configuration on MPLS Cloud-facing Port
A FastEthernet or GigabitEthernet port from an ML-Series card in the RPR must connect to the interface
of a router that is part of the MPLS cloud. A bridge group must be created that contains this FastEthernet
or GigabitEthernet port and the SPR subinterface. Interface GigE 0 on card B and card D plays this role
in
Figure 18-2 on page 18-10 .
To provision the MPLS cloud-facing port for EoMPLS, perform the following procedure, beginning in
global configuration mode:
Command Purpose
Step 1 Router(config)# mpls label protocol
ldp
Specifies LDP as the label distribution protocol.
LDP must be specified. The ML-Series card does not
operate EoMPLS with the default TDP as the label
distribution protocol.
Step 2 Router(config)# interface spr 1 Enters RPR interface configuration mode.
Step 3 Router(config-if)# ip address
ip-address mask
Assigns an IP address to the RPR interface for MPLS.
Step 4 Router(config-if)# mpls ip Implements tag switching on the SPR interface.
Step 5 Router(config-if)# end Exits interface configuration mode.
Step 6 Router# copy running-config
startup-config
Saves the running configuration file to the startup
configuration file.
Command Purpose
Step 1 Router(config)# bridge bridge-group-number
protocol {rstp | ieee}
(Optional) Assigns a bridge group number and
defines the appropriate spanning-tree type: either
IEEE 802.1D Spanning Tree Protocol or
IEEE 802.1W Rapid Spanning Tree.
Step 2 Router(config)# interface {GigabitEthernet
| FastEthernet } interface-number
Enters interface configuration mode to configure
the MPLS cloud-facing FastEthernet or
GigabitEthernet interface of the ML-Series card.
Step 3 Router(config-if)# bridge-group
bridge-group-number
Assigns a network interface to a bridge group.
Step 4 Router(config-if)# no shutdown Changes the shutdown state to up and enables the
interface.
