You dont just wait until all connections exit, you first need to withdraw bgp announcement to the edge router, then start the wait. It’s not that simple with metal LBs. On the other hand it’s not that simple with cloud LBs either bc they also break long tcp streams when they please

We reused the LB as much as possible to avoid the BGP thing. There's a thing called MetalLB designed around that though.

Pretty sure metallb will have same problem when you need to rotate nodes in bgp mode
