This could be a problem Usually the lowest TTL on the wire is '1' - the next router then subtracts 1, the value is zero, and the packet is dropped on the same router (and icmp sent back). If someone didn't put an aditiional if() to check, this could cause many problems, especially with broadcasts. And why would they check, if no device sends out packets like this normally (without someone else not doing an if() check, or if someone sent those packets on purpose). |
