All-- Now that GateD deployment is nearly complete on AS 690, we will soon be seeing Aggregates both on the backbone and in the Policy Routing Database reports. Current plans call for controlled routing of a few aggregates on AS 690 starting Monday (Feb 28). A few aggregates may be added to the PRDB for the Tuesday morning config run; this will be the first time that nets with prefix lengths other than 8, 16, or 24 will have appeared in PRDB reports. Assuming that this controlled deployment works as expected, we will begin accepting NACRs for aggregates next Friday, March 4. Please be sure to use the new NACR form available from nic.merit.edu in the file "nsfnet/announced.networks/template.net.v7.1" . ------------ How to submit an Aggregate for Routing on AS 690 ------------- The same NACR template is used for submitting all nets (e.g., classful nets, classless nets, aggregates). For aggregates, follow the "netnum" by a slash character and then the prefix length, i.e.: netnum: 198.108.12/22 Generally, in order to aggregate a block of nets that all ready are routed by AS 690, you should make sure that those nets all have the same AUP and AS 690 announcement lists. The command "whois -h prdb.merit.edu 'aggchk <net_ip/len>'" can help you with this check:

$ whois -h prdb.merit.edu 'aggchk 198.108.12/22'

198.108.12/22 is an aggregate equivalent to 4 Class Cs: 198.108.12 to 198.108.15

More complicated mixes of routing policies can be discussed, but they will slow the processing of your NACR. --Dale Johnson
