The system must not forward IPv6 source-routed packets.

| V-22553 | GEN007920 | SV-38378r1_rule | ECSC-1 | Medium |
| Description |
|---|
| Source-routed packets allow the source of the packet to suggest routers forward the packet along a different path than configured on the router, which can be used to bypass network security measures. This requirement applies only to the forwarding of source-routed traffic, such as when IPv6 forwarding is enabled and the system is functioning as a router. |
