Snort alarm sameip

[Philip Edwards <phil.e () clara net>]

Hi,

Can anyone hazard a guess why the sameip keyword is triggering an alarm on a DHCP request.
The source is 0.0.0.0 the destination is 255.255.255.255 
The rule is the default: bad-traffic rule

alert ip any any -> any any (msg:"BAD-TRAFFIC same SRC/DST"; sameip; reference:bugtraq,2666; reference:cve,1999-0016; 
reference:url,www.cert.org/advisories/CA-1997-28.html; classtype:bad-unknown; sid:527; rev:8;)

phil@Rangoon:~$ snort --version

I could add exceptions to filter this out but would i like to know why it's being triggered.

Thanks
