I think perhaps there are some bugs in MCU Lin's bgp patch. They are not bugs of coding, but of ideas.
BGP is a dynamic routing protocol, the best routes of bpg is not only decided by any deamon connect to u, but also urself. So it is useless if you want to use a blackhole deamon to simulate a real deamon even you put the dummy deamon on the right postion and with the right connections.
for example.
router A --------router B----router D ---------router C
| |
|----------------- your Router--------------------|
|----------------- your Dummy-------------------|
U can see , the router A and route C, whose decisions depend on your Router's decision, when you put your Dummy beside your Router, the decisions you receive is desicion made by all the routers, remenber, it is also include your Router( Because at least Router A and Router C are influenced by your Router). That is to say, It's a result made by not only your new configuration( Input configration of your Dummy) ,but also your old configuration(Input and output configuration of your Router). So it is useless to use the new configuration to evaluate the old configutation.
Do you think so?
