(the ruters use zebra) To configure incoming traffic to 194.141.24.0/24, you should create route maps on C, like this: match community 6802:(1,2)00 set as path prepend XXXX XXXX and attach this route maps to corresponding neighbor (don't forget "out" keyword). To deal with outgoing traffic, you should create route maps on A, like this: match commnity 6802:(1,2)00 set localpref 110 and attach them to corresponding neighbors, with "in" keyword. -- Totus tuus, Glebius.
