+.\" The following taken from 2.6.28-rc4 Documentation/networking/ip-sysctl.txt
+If enabled, ICMP error messages are sent with the primary address of
+the exiting interface.
+
+If non-zero, the message will be sent with the primary address of
+the interface that received the packet that caused the ICMP error.
+This is the behavior that many network administrators will expect from
+a router.
+And it can make debugging complicated network layouts much easier.
+
+Note that if no primary address exists for the interface selected,
+then the primary address of the first non-loopback interface that
+has one will be used regardless of this setting.
