I am not familiar with the ISP enviroment at all.
When we say UUNet uses IS-IS on their core, do we mean that they
redistribute their BGP routes from their edge routers into IS-IS and
redistribute back into BGP and the far end edge routers?
Which means the edge routers are running BGP to learn customers' routes and
redistribute these routes into IS-IS to router across the UUNet core? Just
want to verify that I understand this correctly.
Thanks
