Hi, So what happens to multihoming assignments made by the ISP? That means the multihoming assignment can't be used as a backup. If the customer's connection to the ISP which made the multihoming assignment gets lost, then it can't use its multihoming assignments (say a /24) to get traffic from some other ISP?!
