Hi Dimitre,
VIP on node where public eth is down, will failover to other node/nodes and all resources dependant on it will also failover ... dependant resources you can find with following:

oracle_at_main-gc-1@+ASM1: ~
-bash-3.2 $ crsctl stat res -p | egrep -i '^name|START_DEPENDENCIES' NAME=ora.GC_OCR_VOTE.dg
START_DEPENDENCIES=hard(ora.asm) pullup(ora.asm) NAME=ora.LISTENER.lsnr
START_DEPENDENCIES=hard(type:ora.cluster_vip_net1.type) pullup(type:ora.cluster_vip_net1.type)
NAME=ora.LISTENER_SCAN1.lsnr
START_DEPENDENCIES=hard(ora.scan1.vip)
dispersion:active(type:ora.scan_listener.type) pullup(ora.scan1.vip) NAME=ora.LISTENER_SCAN2.lsnr
START_DEPENDENCIES=hard(ora.scan2.vip)
dispersion:active(type:ora.scan_listener.type) pullup(ora.scan2.vip) NAME=ora.LISTENER_SCAN3.lsnr
