Article ID: TN76 TECHNOTES Last Updated: 05 Jan 2010Version: 2.0
Description:
The track IP feature was missing from the initial release of the Juniper Networks® SRX Series Services Gateways platform, and in response to this, a JUNOScript API was created to implement this feature. The JUNOScript API track IP implementation allows the user to utilize this critical feature on the SRX Series platforms. It allows for path and next-hop validation through the existing network infrastructure with the ICMP protocol. Upon the detection of a failure, the script executes a failover to the other node in an attempt to prevent downtime.
The second SRX Series high availability (HA) feature implemented is interface monitoring. Interface monitoring is an included feature on the platform but it may not meet all customer requirements. The script implements all of the features that are included on the SRX Series platform plus the ability to limit the failover of the control plane. In some scenarios, if the control plane is rapidly failed over, it can cause instability. This implementation of interface monitoring accounts for this possibility and limits the user to monitoring only the data plane.
