We operate a small mpls core, which I’m pretty green at.
Currently the setup is that every PE will use the same RD for customer1, and another for customer2. Recently we have had a consultant in who said that the RD should be unique per customer and per PE.
I’m going to lab this up to see what differences it makes, just wondering how you would usually see this in production?
I’ve had issues recently dual-homing bgp with clients - unable to use the same AS on the 2 pe bgp sessions in our environment as only one will learn routes. This is making me think it’s due to both PEs having the same RD set for that customer, meaning the vpnv4 route is not unique
