Example: Configuring Protection Switching Between Psuedowires
Requirements
This example uses the following hardware and software components:
- Junos OS Release 11.2 or later
- 2 MX Series PE routers
Overview and Topology
The physical topology of the protection switching between psuedowires example is shown in Figure 1.
Figure 1: Topology of a Network Using VPWS Psuedowires
The following definitions describe the meaning of the device abbreviations used in Figure 1.
- Customer edge (CE) device—A device at the customer site that provides access to the service provider’s VPN over a data link to one or more provider edge (PE) routers.
- Provider edge (PE) device—A device, or set of devices, at the edge of the provider network that presents the provider's view of the customer site.
Configuration
Step-by-Step Procedure
To configure protection switching between psuedowires, perform these tasks:
- Configure automatic protection switching.protocols {protection-group {ethernet-aps {profile-1 {protocol g8031;hold-time 1000s;revert-time 5m;}}}
- Configure the connectivity fault management.ethernet {oam {connectivity-fault-management {maintenance-domain md1 {level 5;
- Configure the continuity check message for the working
path.maintenance-association W {protect maintenance-association P {aps-profile profile-1;}continuity-check {interval 1s;}mep 100 {interface ge-1/0/0.0 working;direction down;auto-discovery;}}
- Configure the continuity check message for the protection
path.maintenance-association P {continuity-check {interval 1s;}mep 100 {interface ge-1/0/0.0 protect;direction down;auto-discovery;}}
Results
Check the results of the configuration:
protocols {protection-group {ethernet-aps {profile-1 {protocol g8031;hold-time 1000s;revert-time 5m;}}}ethernet {oam {connectivity-fault-management {maintenance-domain md1 {level 5;maintenance-association W {protect maintenance-association P {aps-profile profile-1;}continuity-check {interval 1s;}mep 100 {interface ge-1/0/0.0 working;direction down;auto-discovery;}}maintenance-association P {continuity-check {interval 1s;}mep 100 {interface ge-1/0/0.0 protect;direction down;auto-discovery;}}}}}}
