How can you load share using BGP to a service provider using six individual T1s between our router and theirs?

Technical difficulties have prevented us from getting a fractional T3 or IMA connection to our second service provider. Instead we must use six individual T1s and load share. BGP only supports a single route. How can we do this?

Re: How can you load share using BGP to a service provider using

Use loopback interface to setup your

BGP peering with the isp router and configure

six static routes to loopback with each one pointing

to each serial interfcae next-hop.
