You can configure an N:1 warm standby option for MS-MPCs, MS-MICs, and MX-SPC3s by creating
multiple aggregated multiservices (AMS) interfaces, each of which contains the service
interface you want to backup and the service interface that acts as the backup. The same
backup service interface can be used in all these AMS interfaces.
Starting in Junos OS
Release 19.3R2, the N:1 warm standby option is supported on the MX-SPC3.
To configure warm standby for services interfaces:
- Create an AMS interface.
[edit interfaces]
user@host# set amsN
The variable N is a unique number, such
as 0 or 1.
- Specify the primary service interface that you want to
backup.
[edit interfaces amsN]
user@host# set redundancy-options primary mams-a/b/0
The variable a is the FPC slot number and b is the PIC slot number for the primary service interface.
- Specify the secondary service
interface, which backs up the primary interface.
[edit interfaces amsN]
user@host# set redundancy-options secondary mams-a/b/0
The variable a is the FPC slot number and b is the PIC slot number for the secondary service interface.
- Repeat Steps 1 through 3 to create an AMS interface
for each service interface that you want to backup. You can use the
same secondary service interface in each AMS interface.
