Matches on conntrack rpl ct_state.
Example:
$ tc filter add dev ens1f0_0 ingress prio 1 chain 1 proto ip flower \
ct_state +trk+est+rpl \
action mirred egress redirect dev ens1f0_1
$ tc filter add dev ens1f0_1 ingress prio 1 chain 1 proto ip flower \
ct_state +trk+est-rpl \
action mirred egress redirect dev ens1f0_0
