Recommended option for single homed hosts and stub network
routers. Could cause troubles for complicated (not loop free)
networks running a slow unreliable protocol (sort of RIP),
or using static routes.
- 1 - (DEFAULT) Weaker form of RP filtering: drop all the packets
- that look as sourced at a directly connected interface, but
- were input from another interface.
-
0 - No source validation.
- NOTE: do not disable this option! All BSD derived routing software
- (sort of gated, routed etc. etc.) is confused by such packets,
- even if they are valid. When enabled it also prevents ip spoofing
- in some limited fashion.
-
- NOTE: this option is turned on per default only when ip_forwarding
- is on. For non-forwarding hosts it doesn't make much sense and
- makes some legal multihoming configurations impossible.
+ Default value is 0. Note that some distribution enable it
+ in startip scripts.
