L3VPN over EVPN MPLS Configuration
This chapter includes step-by-step configurations for L3VPN over EVPN MPLS.
Overview
L3vpn EVPN MPLS ensures that we are able to do the Ip-vrf to Ip-vrf routing with MPLS as overlay. We can ensure that with this model we can do the Anycast gateway using EVPN concepts. L3VPN EVPN MPLS is a way of integrating the interface-less model. In this model we will use non-irb interface i.e. L3 interface for the Ip-Vrf routing.
Using Anycast gateway idea is to have the Multi-Homed PE nodes to work in active-standby mode. From remote perspective at one time only one Peer PE will be active. If that PE goes down, then a new tunnel to the peer PE will be established for the traffic. From the access-side Traffic can reach to either of the peer PE and sent across the remote PE nodes. This way we can achieve redundancy using the anycast mac-address.
Topology
Below Topology depicts the topology for the L3VPN over EVPN MPLS configuration examples for both single homing and multi-homing with SR/LDP. MLAG configured between PE1 and PE2 to achieve multi-homing Active-Standby connected to CE1.
