Which is described in chapter 6 of the documentation you quote. > [https://documentation.suse.com/sle-ha/15-SP1/html/SLE-HA-all/static/images/logo.png]<https://documentation.suse.com/sle-ha/15-SP1/html/SLE-HA-all/cha-ha-geo-ip-relocation.html> > Setting Up IP Relocation via DNS Update | Geo Clustering Guide | SUSE Linux > Enterprise High Availability Extension 15 > SP1<https://documentation.suse.com/sle-ha/15-SP1/html/SLE-HA-all/cha-ha-geo-ip-relocation.html> > In case one site of your Geo cluster is down and a ticket failover appears, > you usually need to adjust the network routing accordingly (or you need to > have configured a network failover for each ticket).
