it is worth mentioning… i once bumped into this quite by surprise and it shook me… serial line address resolution protocol… there is not a lot out there on it… it’s basically a dhcp mechanism for serial interfaces supporting a /30 network, whereby the side that is unknown get’s the other half of the /30… this guy has more on it here:

it is a legacy from what i have gathered…

wiki discusses it here briefly:

if in use it will show up as the method for which it came to be in show ip interface brief…

beware the SLARP monster…
