Have one question about VRF aware NAT for internet access! If we will enable the VRF aware NAT on local PE to have an internet access via centeral Internet PE then we will not have connectivity to any other VPN site as all local CE prefixes will be translated to the loopback IP address of the local PE.
We can have route map which will match the ACL for specific CE source to specific VPN destination with deny key word and it will prevent the NAT when CE will try to communicate with other CE of same VPN or different VPN. That looks longer configuration in real world right! so is that the only way I have when I will have only one option to configure the locap PE with VRF aware NAT to gain internet access?
I need to know what is the implement in real world? How service provider networks are providing internet access with MPLS VPN option? I know about customer is getting VPN connectivity on one router and service provider will give other internet connectivity link which might be terminating on same router or other router.
