PBR support for the VXLAN BGP EVPN fabric

Policy-based routing (PBR) support is provided for the Virtual eXtensible Local Area Network (VXLAN)
Border Gateway Protocol (BGP) Ethernet VPN (EVPN) fabric. PBR allows you to configure a defined policy
for IPv4 and IPv6 traffic flows, lessening reliance on routes derived from routing protocols. All packets
received on a PBR enabled interface are passed through enhanced packet filters or route maps. The route
maps dictate the policy, determining where to forward packets. PBR configurations have to be enabled on
relevant Top of Rack (ToR) or leaf switches, and spine switches in the VXLAN BGP EVPN fabric. For
more information on PBR, see
