Operations with distributed virtual routers
In deployments using distributed virtual routers, the BGP speaker advertises floating IP addresses and self-service networks differently. For floating IP addresses, the BGP speaker advertises the floating IP agent gateway on the corresponding compute node as the next-hop IP address. For self-service networks using SNAT, the BGP speaker advertises the DVR SNAT node as the next-hop IP address. This means that traffic directed to a self-service network behind a distributed virtual router must traverse a network node, while traffic to a floating IP will avoid routing through a network node.
