In this case it is helpful if ASpath length within confederation is considered as true eBGP. Now I set MED statically. Thank you for information of "set metric +/-[VALUE]" statement, I'll try it. Nowaday, iBGP Reflecter is preferred to BGP Confederation. When we use single IGP within AS, reflecter and confederation make little difference. But confederation enable us to divide IGP into sub-ASes. It may make sense a lot. And in such a network configuration, it is natural that AS path length consideration while route selection is required. How do you like this idea?? Is it IDR topic?? :| -Andy :| ----- MAEMURA Akinori Network Engineer, C&C Internet Service mesh, NEC Corporation, JAPAN maem@mesh.ad.jp, maemura@mms.mt.nec.co.jp
