Its complicated to explain, it was site that was shared by 2 clients who 
shared a physical network but have since split networks (still on the 
same premises) they share certain services but now have separate routers 
and breakout links which they dont want each others traffic to flow 
across but still want to provide access to other services/networks NOT 
connected to router A.

I know I could achieve this with firewall rules etc it just seemed a 
better solution just to not advertise the routes not needed on each 
respective router...

there are more devices than just routers A B C, wish I was good at asci 
art I could create a small diagram.



Thank you,
