Redundant circuit fail over capabilities

Bvance — Fri, 13 Oct 2017 14:48:50 GMT

This is a general question about PAN capabilities.

We are looking at acquiring a second, slower circuit for internet access backup. We would like this to be an automated fail over. I am trying to see if our PA 3050's are capable of this and am looking for the documentation on how to set this up on the PANs.

Also, not sure how to route public DNS resolutions down second circuit after failover.

Thanks,

If you have fast connection and slow connection and wish to use slow only as failover then use Policy Based Forwarding.

Point PBF rule towards your fast ISP and default route in virtual router towards slow ISP.

If fast ISP next hop is unavailable then PBF will fail over to standard routing table.
