Re: isp routing

Two version are available:

1) static route point to the customer network in the ISP router and in the customer router there is a default static route to the ISP router

2) BGP solution

In the ISP backbone ore cloud ISPs use BGP...

I don't really understand your question about the next hop, please explain it in more detail..

bye

Re: isp routing

if you only have one connection to the internet, you will not be using BGP as i'm guessing your internal IP network is private.

the internet firewall or router simply has a default route to the ISP and your PCs have a default route to either the firewall or local router. no BGP required in this scenario.

the next hop for your internet router is just that, the next hop...(this would be the IP address of the ISPs WAN connection to your router)
