EVPN for VXLAN in R-VPLS Services Example

This section shows a configuration example for three 7750 SR, 7450 ESS, or 7950 XRS PEs in a Data Center, based on the following assumptions:

PE-1 is a Data Center Network Virtualization Edge device (NVE) where the following services are configured:

• R-VPLS 2001 and R-VPLS 2002 are subnets where Tenant Systems are connected

• VPRN 500 is a VPRN instance providing inter-subnet forwarding between the local subnets and from local subnets to the WAN subnets

• R-VPLS 501 is an IRB backhaul R-VPLS service that provides EVPN-VXLAN connectivity to the VPRNs in PE-2 and PE-3

PE-2 and PE-3 are redundant Data Center Gateways providing Layer 3 connectivity to the WAN for subnets ‟subnet-2001” and ‟subnet-2002”. The following configuration excerpt shows an example for PE-2. PE-3 would have an equivalent configuration.
