Hi,

I have a new failover T1 configuration that is currently running on the failover side due to a router being down. I am running BGP with partial routes. Since the install I can not get speeds of any greater than 345k down and 900k up. Pinging the wan interface of my router shows alot of packet loss but my interfaces are clean and I have tried a different cable run. I can ping my upstream with <10ms replies and have tested out in front of the router and am getting full speed. I did a router reload this evening and now have only gotten one prefix. Was getting them earlier. My hardware is not taxed at all and I am baffled. Here is my show run:

Try adding a default route and enabling ip classless

ip classless
ip route 0.0.0.0 0.0.0.0 x.x.x.x  <== "upstream" ip of your ISP

By omitting all the IP address info you may have hidden a possible BGP issue (flapping). Can you check if your BGP neighbors are statically reachable (either directly connected or you have to add a static route; otherwise a BGP can experiencing an internal loop if a nex-hop is also learned via BGP and the neighborships start flapping).
The other common cause of problems is the autonegotiated speed and duplex on the ethernet ports. I suggest you change that to whatever is really supported by the other end (e.g. "duplex full" and "speed 100").
