Quick question: do you allow/run routing protocols between your (isp-)
network and your customer?
If so: which protocols?
If not: what reasons do you tell the customer?
In particular I am interested to know about setups when they want to
announce the prefix/subnet you assigned them from your PA-space back to
you because they want to run redundant routers.
The setup would probably look like this:
Customer Subnet 10.0.0.0/27
[customer router a] - <routing protocol x> - [customer router b]
<routing protocol y> <routing protocol y>
[isp router a] - <routing protocol z> - [isp router b]
ISP Network 10.0.0.0/8
