Hi, I have setup a *VPLS *scenario successfully and now I want to setup a *L3VPN *scenario in VPP (L3VPN topology is in attachment).
My configuration for VPLS is some how like this link <https://lists.fd.io/g/vpp-dev/topic/vpls_dev_in_vpp_1/18091281?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,0,18091281> . As far as I searched Internet, L3VPN has a *VPN Label* that I think is somehow like *PW Label* in VPLS with difference that *VPN Label is used to select VRF* and *PW Label is used to select mpls tunnel *(hence bridge). =============================== *Part1:* I guess I should configure the *source PE* as follow: *In VPLS: mpls tunnel add l2-only via <PE-TARGET> out-labels <PW-LABEL>* * ip route add <PE-TARGET> via <NEXT-HOP> out-labels <MPLS-LABEL>* *In L3VPN: CMD1 ??????????????? (insert in customer VRF)* * ip route add <PE-TARGET> via <NEXT-HOP> out-labels <MPLS-LABEL> (insert in GLOBAL VRF)* I don't know what command I should use for CMD1 ... This command must add VPN-LABEL which is selected base on the customer's VRF to the packet and then lookup the GLOBAL VRF to push the MPLS Label. just like VPLS that the mpls tunnel first adds a PW Label and then in the destination IP resolution, MPLS Label is added to packet. *Question1:* Am I right about the configurations in the source PE? ================================ *Part2:* I guess I should configure the *target PE* as follow: *In VPLS: mpls local-label add eos <PW-LABEL> via l2-input-on <MPLS-TUNNEL>* * In L3VPN: mpls local-label add eos <VPN-LABEL> via ip4-lookup-in-table <VRF-ID> (insert in GLOBAL VRF) * *Question2:* Am I right about the configurations in the target PE? ================================= *Part3:* In order to fill customer's VRF, I should use control plane's RouteTarget (RT) to select the VRF ID and then use below command to fill the VRF: *ip route add <DESTIANTION> via <NEXT-HOP> <INTERFACE> table <VRF-ID>* *Question3:* Am I right? thanks in advance
