Use case: Want to run multiple bng-blaster instance using same physical nic interface Problem: 1.bngblaster application dose not support associating same interface on multiple instances 2.If we create Linux bridge and associate physical interface & veth pairs we could see broadcast packets from one veth interface flooded to other veth interface (normal switch behavior)   e.g - created bridge 'br-access' associated physical nic 'eth1' & veth interfaces veth-access1 & veth-access2            Veth pairs : (veth-access1<--->access1)  &&  (veth-access2<--->access2)            Here broadcast packets from access1 is flooded to access2 Solution: Enable port isolation for veth interfaces eg:- bridge link set dev veth-access1 isolated on bridge link set dev veth-access2 isolated on Configuration: ### Access side interface ### # Create bridge ip link add br-access type bridge ip link set...
