DecIP6HLIM — Click element;
DecIP6HLIM()
Ports: 1 input, 1-2 outputs
Processing: agnostic, but output 1 is push
Expects IP6 packet as input. If the hlim is <= 1 (i.e. has expired), DecIP6HLIM sends the packet to output 1 (or discards it if there is no output 1). Otherwise it decrements the hlim, and sends the packet to output 0.
Ordinarily output 1 is connected to an ICMP6 error packet generator.
This is a typical IP6 input processing sequence:
... -> CheckIP6Header -> dt::DecIP6HLIM -> ...
dt[1] -> ICMP6Error(...) -> ...
