But, we don't have a central router? If your border to the exchange right now got a prefix with the next hop of 206.108.255.3, how'd you get there? You'd have no route to host for 206.108.255.3. That is why I brought up the secondary IPs. Once everybody puts in a secondary IP in 206.108.255.0/24, they'll know how to try to get to 206.108.255.3 for my prefix announcement. But I can't really do the prefix announcement with the next-hop in 206.108.255.3 until everybody knows how to get to 206.108.255.0/24? -- Doug McIntyre <[log in to unmask]> -- ipHouse/Goldengate/Bitstream/ProNS -- Network Engineer/Provisioning/Jack of all Trades ######################################################################## To unsubscribe from the MICE-DISCUSS list, click the following link: http://lists.iphouse.net/cgi-bin/wa?SUBED1=MICE-DISCUSS&A=1
