Here is an amusing BGP problem : Wild Wolrd-----------R1--------------R2------Our Networks There is an IBGP sesion running between R1 and R2. R2 advertises route 194.214.0.0/16 to R1. In our block there is a class C used by one of our customer which is not directly connected to our network. This customer advertises its class C to the Wild World via its own ISP. R1 receives the 194.214.253.0/24 advertisement from the Wild World, it stores it in its routing table; however R2 never takes it into account : its routing table only mentions 194.214.0.0/16 , it doesn't mention the more specific routing entry 194.214.253.0/24. Our Networks cannot get to 194.214.253.0/24. Is it a feature of IBGP ?? Thanks for any help, Pascal ------------------------------------------------------------------------ Pascal Petit SYNET tel: 33 1 4696 0040 74, rue Roque de Fillol fax: 33 1 4696 0041 92800 Puteaux email: [email protected] FRANCE http://www.synet.fr
