Hi, everyone
I searched this topic on the forum, it seems that no final solution for this issue.
The only ways to achieve this target i found in the forum is as follows:
1. configured on the EBGP neighbor with as-prepend out (it really works, but in some situation it does not allowed to configured on neighbor router)
2. using aggregate address with route-map out locally (it works, but still has some problems)
3. "ip local policy" ( seems not to work)
Can someone illuminate me in the question?
