Configuring
DLSw+ Configuration Task List
Ethernet Redundancy
The DLSw+ Ethernet Redundancy feature, introduced in Cisco IOS Release 12.0(5)T, provides redundancy and load balancing between multiple DLSw+ peers in an Ethernet environment. It enables DLSw+ to support parallel paths between two points in an Ethernet environment, ensuring resiliency in the case of a router failure and providing load balancing for traffic load. The feature also enables DLSw+ to support multiple DLSw+ routers on the same transparent bridged domain that can reach the same MAC address in a switched environment.
To enable the DLSw+ Ethernet Redundancy feature, issue the following command in interface configuration mode:
Command | Purpose |
|
|
Configures transparent redundancy. | |
| |
|
|
To enable the DLSw+ Ethernet Redundancy feature in a switched environment, enter the following commands in interface configuration mode:
| Command | Purpose |
Step 1 |
|
|
Enables DLSw+ Ethernet Redundancy feature when using a switch | ||
| device. | |
Step 2 |
|
|
Configures a single destination MAC address to which multiple MAC | ||
| map local mac mac address remote mac | addresses on a transparent bridged are mapped. |
| mac address neighbor mac address |
|
|

The Ethernet Redundancy feature is a complex feature. See the DLSw+ Design and Implementation Guide for more details. Refer to the “DLSw+ with Ethernet Redundancy Configuration Example” section on page 331 and the “DLSw+ with Ethernet Redundancy Enabled for Switch Support Configuration Example” section on page 332 for sample configurations.
Backup Peers
