Have you ever received many networks from your customers without being able to summarize with an IGP? And… have you ever had to make BGP transit for these messy networks to a carrier that accepts only /20 networks or even worse check on RIPE.NET database?
Little trick with aggregate command:
#Huawei slang:
#
bgp 65001
ipv4-family unicast
aggregate 10.10.10.0 255.255.240.0 detail-suppressed
#Warning: aggregate command not work if you advertize messy networks with network command.
Now the Carrier or the IX will receive nice networks!!!
