-"""
-When an IPSec SPD is configured on an interface, any inbound packets
-not matching inbound policies, or outbound packets not matching outbound
-policies, must be dropped by default as per RFC4301.
-
-This test uses simple IPv4 forwarding on interfaces with IPSec enabled
-to check if packets with no matching rules are dropped by default.
-
-The basic setup is a single SPD bound to two interfaces, pg0 and pg1.
-
- ┌────┐ ┌────┐
- │SPD1│ │SPD1│
- ├────┤ ─────> ├────┤
- │PG0 │ │PG1 │
- └────┘ └────┘
-
-First, both inbound and outbound BYPASS policies are configured allowing
-traffic to pass from pg0 -> pg1.
-
-Packets are captured and verified at pg1.
-
-Then either the inbound or outbound policies are removed and we verify
-packets are dropped as expected.
