Eric,

Could not find anything on the web, so had to type this from my
hardcopy:

Community	AT&T IP Bacbone Function
Received

None, 7018:100	Localpref 100 assigned - primary routes
7018:90		localpref 90 -customer backup routes (INTRA-AT&T)
7018:80		localpref 80 -Routes equal to peer routes
7018:70		localpref 70 -customer provided backup (INTER-AT&T
		and other ISP)
7018:20 (deflt) Assign comm. 7018:2000 to routes (announce to peers
		and customers) not needed for customer-owned IP's
7018:25		assign 7018:2500 to routes (announce to customers only)
7018:21		assign 7018:2010 (!) (not advertised to peers or cust.)

hope this helps.
