Hi, Group,

According to theory, BGP will choose external router rather than
confederation external, and confederation external will take preference
than internal, when all other BGP attributes are the same. But in my own
lab, I tested that it's not true and BGP will choose the lower metric (if
metric not the same), even it won't regard whether it's BGP external or
confederation external (if metric the same, it choose lower router ID).
Just want to ask whether someboday has the same experience or it just a bud
in my IOS image. (I have tested several scenarios and gives the same
result)

Also, I would like to ask whether you guys has experience in redistributing
BGP into IGPs? by theory, BGP will not redistribute iBGP routes (only eBGP
routes) when you do "redistribute bgp AS_no" command in any IGP, but I
tested that if the route is belongs to confedration external, it still will
be redistributed into IGP. Just want to ask experienced guy to firm my
testing.

Thx a lot!,
