Hi guys,
I'm working on a double eBGP connection. The first one it is OK with my main ISP (Cogent, 1Gbps) but at the time that I make the second BGP session with my ISP2 (Transtelco, it is my ISP backup) my network seems to be slow even when the traceroutes tell that my LAN is going out via my main ISP (Cogent).
When I made shutdown to Transtelco on the router bgp process (neighbor X.X.X.X shutdown) the network seems to be faster than with the Transtelco's session up.
I attached you my configuration. What I need to do is that, if my main ISP (Cogent) goes down, Transtelco goes up automatically. In the mean time, all the network must go out via Cogent.

I hope you can help me to figure it out. I'm new on BGP :).
Thanks in advance.
