We will soon be setting up a hot site at Time Warner, which is our current ISP, and wondered if anyone could send a link or sample IOS config for setting up BGP for redundancy.
Not sure what you mean by hot site, are they giving you /24 address, how many routers are going to be at your site? Also why BGP do you need to exchange routing info with the internet? In other words will you be hosting or offering a path to some web servers? If not BGP may be over doing it. I have some configs that may help you just need to your scenerio better.

We are using them for redundancy incase of an outage at our primary location. We will have a metro ethernet connection to them and use OSPF for internal communications. However, we have many offsite users who will need vpn access and TW is giving us another Internet connection to the hotsite.
The ISP router is in lets say AS 65501
Router2# configure terminal
Router2(config)# interface Serial0
Router2(config-if) ip address 192.168.55.5 255.255.255.252
Router2(config-if)# exit
Router2(config)# router bgp 65501
Router2(config-router)# network 172.25.17.0 mask 255.255.255.0
Router2(config-router)# neighbor 192.168.55.6 remote-as 65500
Router2(config-router)# no synchronization
Router2(config-router)# exit
Router2(config)# end
Router2#
I used private address and AS's in this example for obvious reasons, the ISP will take care of the router2 part but I included it for the example.
This is a basic setup but it should help.
