For a Virtual Chassis configuration consisting of two
MX Series routers or two EX9200 switches, each of which supports dual
Routing Engines, you must create and apply on the primary device of
the Virtual Chassis the following configuration groups, instead of
using the standard re0 and re1 configuration groups:
member0-re0
member0-re1
member1-re0
member1-re1
Note: The membern-ren naming format for configuration groups is reserved for exclusive
use by member routers or switches in EX9200 or MX Series Virtual Chassis
configurations.
Using configuration group names of the form membern-ren in an existing non-Virtual
Chassis configuration or configuration script could interfere with
Virtual Chassis operation. This misconfiguration could cause the router
or switch to assign no IP address or an incorrect IP address to the fxp0 management Ethernet interface, and could result in a display
of the Amnesiac prompt during login.
To create and apply configuration group information from
the router or switch to be configured as the primary of the Virtual
Chassis:
- In the console window on the primary router or switch
(member 0 in this procedure), create and apply the member0-re0 configuration group.
[edit]
user@host# copy groups re0 to member0-re0
user@host# set apply-groups member0-re0
- Delete the standard re0 configuration group from
the global configuration on member 0.
[edit]
user@host# delete apply-groups re0
user@host# delete groups re0
- Create and apply the member0-re1 configuration
group.
[edit]
user@host# copy groups re1 to member0-re1
user@host# set apply-groups member0-re1
- Delete the standard re1 configuration group from
the global configuration on member 0.
[edit]
user@host# delete apply-groups re1
user@host# delete groups re1
- Create and apply the member1-re0 configuration
information.
[edit]
user@host# set groups member1-re0 system host-name host-name
user@host# set groups member1-re0 system backup-router address
user@host# set groups member1-re0 system backup-router destination destination-address
user@host# set groups member1-re0 system backup-router destination destination-address
...
user@host# set groups member1-re0 interfaces fxp0 unit unit-number family inet address address
user@host# set apply-groups member1-re0
The commands in Steps 5 and 6 set the IP address for the fxp0 management interface and add an IP route for it in the
event that routing becomes inactive.
- Create and apply the member1-re1 configuration
information.
[edit]
user@host# set groups member1-re1 system host-name host-name
user@host# set groups member1-re1 system backup-router address
user@host# set groups member1-re1 system backup-router destination destination-address
user@host# set groups member1-re1 system backup-router destination destination-address
...
user@host# set groups member1-re1 interfaces fxp0 unit unit-number family inet address address
user@host# set apply-groups member1-re1
- Commit the configuration.
Best Practice: We recommend that you use the commit synchronize command to save any configuration changes to the Virtual Chassis.
For an EX9200 or MX Series Virtual Chassis, the force option is the default and only behavior when you issue the commit synchronize command. Issuing the commit synchronize command for a Virtual Chassis configuration has the same effect
as issuing the commit synchronize force command.
