• Configure Layer 3 TRM in the BGP EVPN VXLAN fabric before you enable Layer 3 TRM interworking with MVPN. See Configuring Layer 3 Tenant Routed Multicast for detailed steps. • Configure the MVPN network for the VPNv4 address family. See Configuring Multicast Virtual Private Network module of the IP Multicast Routing Configuration Guide . Note Configure MVPN Profile 11 for EVPN VXLAN Layer 3 TRM interworking. For information on how to configure MVPN profiles, refer to Configure mVPN Profiles Within Cisco IOS .
• If internal Border Gateway Protocol (iBGP) is used for peering between the two networks, run the mdt auto-discovery interworking vxlan-pim in VRF configuration mode on the border VTEP. If external Border Gateway Protocol (eBGP) is used for peering between the two networks, run the mdt auto-discovery interworking vxlan-pim inter-as in VRF configuration mode on the border VTEP. Enabling Layer 2 External Connectivity with IEEE 802.1Q Networks The following image shows a sample topology that illustrates Layer 2 external connectivity with an IEEE 802.1Q network: Figure 5:
Layer 2 External Connectivity with IEEE 802.1Q Networks You can also connect the EVPN VXLAN network to a firewall in place of the Layer 2 switch in the above image. To configure Layer 2 external connectivity with an IEEE 802.1Q network, perform the following steps on the external Layer 2 switch: Configuring EVPN VXLAN External Connectivity Enabling Layer 2 External Connectivity with IEEE 802.1Q Networks Configuring EVPN VXLAN External Connectivity 16
