Managing the EVPN-VXLAN Fabric
Up to this point in the configuration of the EVPN-VXLAN fabric, we have used a topology with three virtual networks and one access layer switch that simulates an access closet. Use this section to add a second access switch and a new virtual network.
These configuration examples use the same devices you configured in the How to Configure a Campus Network using EVPN Multihoming configuration example.
Add an Access Layer Switch
Requirements
Overview
Use this section to add a new access layer switch (Access Switch 2) to the network that is multihomed to the same collapsed core switches. Figure 1 shows the physical topology with Access Switch 2.
Configuration
This section shows the step-by-step configuration procedures to add a new access Switch (Access Switch 2) to your network.
Collapsed Core 1 Configuration
Step-by-Step Procedure
Specify the interface to include in the aggregated Ethernet bundle.
content_copy zoom_out_mapset interfaces ge-0/0/6 description "Access Switch 2" set interfaces ge-0/0/6 ether-options 802.3ad ae12
Configure the aggregated Ethernet interface to the new access layer switch and increase the ethernet device-count to two to support the additional aggregated Ethernet interface.
