Deployment Guide

63 Dell EMC Networking Virtualization Overlay with BGP EVPN
A.3 Simulated external network interface configuration
1. Create a loopback interface.
2. Specify an IP address to represent a connection to the external network.
Loopback interface configuration
Gateway/firewall switch
interface loopback0
description testlo0
no shutdown
ip address 1.1.1.1/32
A.4 Upstream interfaces
These interfaces are connected to the border leafs upstream.
1. Create a port channel and assign it to VLAN 1.
2. Assign the interfaces connected to the border leafs to the port channel.
Upstream interfaces
Gateway/firewall switch
interface port-channel 100
switchport access vlan 1
interface range ethernet 1/1/11-1/1/12
channel-group 100 mode active
A.5 Static routes to VNIs
The routes configured here provide a path for external traffic to route to VNIs 1614 and 1615.
1. Configure static routes to VNI 1614, 172.16.14.0, via the VNI 1616 IP addresses configured on
Leaf3a and Leaf3b upstream.
2. Configure a static route to VNI 1615, 172.16.15.0, via the VNI 1616 IP addresses configured on
Leaf3a and Leaf3b upstream.
3. When the configuration is complete, exit configuration mode and save the configuration with the end
and write memory commands.
Static routes to VNIs
Gateway/firewall switch
ip route 172.16.14.0/24 172.16.16.245
ip route 172.16.14.0/24 172.16.16.246
ip route 172.16.15.0/24 172.16.16.245
ip route 172.16.15.0/24 172.16.16.246
