Abstract
Techniques for deploying symmetric routing are disclosed. A system, process, and/or computer program product for deploying symmetric routing includes routing network traffic from a client over a security access network provider virtual private network (VPN) access to a customer network, and enforcing symmetric routing crossing an autonomous system (AS) based on one or more prepended AS routing numbers in a first routing table for inbound traffic and/or based on one or more weights and one or more local preferences in a second routing table for outbound traffic.
