Cisco 2600 T1 w/BGP crawls at 345k.
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:

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
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").
