These are common concepts for Standard Service Graphs and Service Graph Redirects. Service Graph with L4-7 Device in Go-To mode == L3 Service Graph. L4-7 Device in Go-To mode and the SGT has PBR enabled == L3 PBR Node.

Design Challenges

steering traffic to the L4-7 Device traffic symmetry (same service node for inbound and outbound traffic), impact of hairpinning traffic on end-to-end network latency.

L4-7 Service Graph
