1. A method, comprising:
creating, by a network device of a network, a routing instance based on a border gateway protocol (BGP) flow specification route,
wherein the BGP flow specification route includes data identifying rate limiting flows in a Layer 3 virtual private network (L3VPN), redirect flows in the L3VPN, and drop flows in the L3VPN;
assigning, by the network device, virtual private network (VPN) parameters based on the BGP flow specification route; and
advertising, by the network device, the VPN parameters within the network,
wherein advertisement of the VPN parameters within the network permits the L3VPN to be generated in the network.
