Internet access over existing mpls vpn

Dear All,

How to access internet over my existing MPLS-VPN connection, what would be the configuration (changes) required in CE and PE.

thanks

Hello Vicky,

one VRF site needs to be connected to the internet via a separate link (easier way to do this)

the CE of that site with internet access has to advertise route 0.0.0.0/0 to PE over the eBGP sessions. PE nodes will propagate this 0.0.0.0/0 within the MPLS L3 VPN to all sites.

device that connects to the internet needs routes for all IP subnets of all sites and also NAT rules to translate all that IP addresses.

Doing that on the PE using a single link requires some work on the PE side to make the VRF natted ip adddresses to communicate with global routing table.

Hope to help

Giuseppe
