I've got a site with multiple Internet links. I want to continuously monitor Internet connectivity across all links although I only plan to use one at a time for production traffic. This is fail over only, not load balancing.
Just routing by link up or down is not sufficient. All of the links terminate as Ethernet on the device, an SRX 240H, with switches between it and the CPE. I found the Real Time Monitoring (RPM) features in JUNOS, and it seemed perfect. I could set up a few ICMP pings and HTTP GETs to some reliable locations and then only fail over when the preferred ISP has more failures than the backup(s). But I'm having problems getting this to work. I thought I could set up a routing instance with the default route out each ISP then set up a RPM test associated with each routing instance, after all, the knobs seem to be in place to do this, but it does not work. From the research I've done, it seems that a forwarding routing instance won't actually affect the packets originating on the host itself? So what is the right way to do this? Am I on the right track? BTW, this is running 10.0, but upgrading is definitely an option. -- Crist Clark Network Security Specialist, Information Systems Globalstar 408 933 4387 _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
