The table itself is fine. I fully support it. The method for generating 
such a table within a router (separate from standard hosts who only 
generate tables for who they need to talk to, and unless you allowed 
forged packets in from remote, shouldn't have an issue) is what is in 

See my other posts. There have been many implementations, mostly for 
security reasons, but also helping with this problem by implementing a 
"router MUST NOT send unsolicited arp requests". It's important that 
routers learn their table in another fashion.
