Configuring the EX 8200 Managment Interfaces for Dual Routing Engines (RE's) with different IP addresses

Article ID: KB15687 KB Last Updated: 26 Nov 2009Version: 1.0
Summary:

This article provides a method for configuring Dual Routing Engines with different IP addresses. 
Symptoms:

Solution:
1. Configure the addresses of the two Routing Engines using configuration groups at the [edit groups] hierarchy level.

2. Use the reserved configuration group re0 and re1 to define properties specific to the individual Routing Engines.

3. Configuring re0 and re1 groups enables both Routing Engines to use the same configuration file.

4. Use the apply-groups statement to reproduce the configuration group information in the main part of the configuration.

5. The commit synchronize command commits the same configuration on both Routing Engines.

The command makes the active or applied configuration the same for both Routing Engines with the exception of the groups, re0 being applied to only RE0 and re1 being applied only to RE1. If you do not synchronize the configurations between two Routing Engines and one of them fails, the routing platform may not forward traffic correctly, because the backup Routing Engine may have a different configuration.


To initially configure a routing platform with dual Routing Engines, follow these steps:

[edit]
root@ex8208# edit groups
[edit groups]
root@ex8200# set re0 system host-name ex8200RE0
[edit groups]
root@ex8200# set re0 interfaces me0 unit 0 family inet address 10.10.10.1/24
[edit groups]
root@ex8200# set re1 system host-name ex8200RE1
[edit groups]
root@ex8200# set re1 interfaces me0 unit 0 family inet address 10.10.10.2/24

Configure the apply-groups statement to reproduce the configuration group information to the main part of the configuration:
[edit groups]
root@ex8200# top
[edit]
root@ex8200# set apply-groups [re0 re1]

Save the configuration changes on both Routing Engines:
[edit]
root@ex8200#commit synchronize
