BGP question

Dear all Something I don't understand and would like you to help. 1/ for the url: http://www.oreillynet.com/pub/a/network/2002/08/12/multihoming.html I don't understand those 2 steps: - Register your routing policy in a Routing Registry. - Use looking glasses to see if your announcements are visible elsewhere on the Internet. How can I register the policy? and how can I use the looking glasses to check? 2/ I saw article. "a full BGP feed is about 110,000 routes." Do you have experience that AMD64 with 3G memory in Unix Box can handle it? Thank you very much and appreciate much for your help
