We recently noticed that sometimes (probably after node reboots) static routes to remote cluster CIDRs added by RouteAgent are overridden by Calico (proto = bird) even though IPPool is set with Disabled=true. Routes added by Calico point inter-cluster traffic to default interface instead of vx-submariner which breaks datapath. Adding DisableBGPExport=true to IPPool solves this issue.
