Does anyone have an example for setting up an internal BGP connection to an ISP? Most of the literature I can find deal with ISP to ISP. Thanks for any assistance.
 
You'll want to setup what's call eBGP or external BGP. Internal BGP or iBGP is sessions between routers in your own AS number.

Example

router bgp 65500
neighbor xxx.xxx.xxx.aaa remote-as 65500
neighbor xxx.xxx.xxx.aaa description iBGP peer from my net
neighbor xxx.xxx.xxx.bbb remote-as 65501
neighbor xxx.xxx.xxx.bbb description eBGP peer from ISP
network aaa.aaa.aaa.aaa mask 255.255.255.0
!announce the aaa.aaa.aaa.aaa/24 subnet
