Hi Experts,I wanted to know about L2VPN functionality with below scenarios., What will be the behaviour of PE1 and PE2 when CE1 is tagged/untagged with different VC type configured.

Hi Experts?
In MPLS L3VPN, VRF in PE routers to distinguish routes from different custmers with same ip subnets and RD is used to distinguish routes from different custmers with same ip subnets on Core (P) routers.

\\RD is used to distinguish overlapping subnets in SP environment and it is PE(provider edge routers where a customer connects to) where you define RD value(not on P routers).\\
Why do we need RD here to achie...
