Computer newbie, do a lesson about the BGP protocol, the external and internal agreement protocol have good match, as shown in figure, R1, R2, R3 AS100, in the same autonomous system using the ospf protocol, R4, R5, R6, in AS200, using the rip protocol, R7 and R8, and R9, in AS300, using the eigrp protocol,
Want to routing redistribution, whether to give every border router configuration three elder brother of the agreement? If the configuration, network segment is connected, only add border or all? Routing redistribution specific how to do? Ask the great spirit show
