Hi all,
I am having a BGP problem, and I am not sure how to solve it. Like Jeff
Doyle's book says: BGP is not a difficult problem, the problem is the
scenario. This is the scenario that I have:
-------------------
| I N T E R N E T |
-------------------
|Link A |Link B
| |
------- Link E -------
| AS 1 | ------ | AS 3 |
-------- --------
|Link C | Link D
| |
--------------------
| I am here |
--------------------
When all links are up everything works fine.
The problem is: When Link "B" goes down, there is not any traffic on Link D.
In this case Link C gets full and my customer start to call me!. I know it
is because there is one more AS hop to reach AS 1, one of the BGP metrics is
the amount of AS hops between links. I can manually add one or two prepends
for AS 3 and the traffic goes ok, I am taking advantage of Link E
My question is: Is there any way that this can be done automaticly?, do I
have to use BGP communities?
Thanks in advanced, any approach is appreciated.
