What happened?
I build a baremetal cluster, use metallb to provide loadbalancer, and deploy a redis-cluster with external access, redis pod needs to access others via loadbalancer, however, when cluster initialize, redis pod access it self via loadbalancer.
so iptables trace like PACKET: 2 693ce7cf OUT=kube-bridge LL=0x0 ffffff8a2affffff9bffffffbf7effffffb8ffffffd648ffffff886bffffff8cffffff8c0800 SRC=10.244.2.233 DST=10.244.2.233 LEN=60 TOS=0x0 TTL=63 ID=59297DF SPORT=42404 DPORT=80 SYN

packet lost, can't access, so I want to test DSR, but DSR can't work.
What did you expect to happen?
see this cri-o/cri-o#6554
use v1.RuntimeService api
How can we reproduce the behavior you experienced?
Steps to reproduce the behavior:
configure kube-router with DSR
annotate service
service can't access

Error setting up IPVS services for service external IP's and load balancer IP's: failed to setup DSR endpoint xxxxxxxx: unable to setup DSR receiver inside pod: failed to prepare endpoint 10.244.2.233 to do DSR due to: rpc error: code = Unimplemented desc = unknown service runtime.v1alpha2.RuntimeService
Additional context
There's any ways to deal with pod access it self via loadbalancer?
