API Guide

● Configure UFD with uplink VLT ports and downlink network ports.
OS10(config)# uplink-state-group 1
OS10(conf-uplink-state-group-1)# enable
OS10(conf-uplink-state-group-1)# downstream ethernet1/1/1-1/1/2
OS10(conf-uplink-state-group-1)# upstream port-channel10
OS10(conf-uplink-state-group-1)# exit
● Configure iBGP unnumbered peering between VLT peers with both IPv4 and L2VPN EVPN address families.
OS10(config)# router bgp 201
OS10(config-router-bgp-201)# template ibgp_unified
OS10(config-router-template)# send-community extended
OS10(config-router-template)# address-family l2vpn evpn
OS10(config-router-bgp-template-af)# activate
OS10(config-router-bgp-template-af)# exit
OS10(config-router-template)# neighbor interface vlan4000
OS10(config-router-neighbor)# inherit template ibgp_unified inherit-type ibgp
OS10(config-router-neighbor)# no shutdown
OS10(config-router-neighbor)# exit
11. Configure IP routing in the overlay network.
● Create a tenant VRF.
OS10(config)# ip vrf tenant1
OS10(conf-vrf)# exit
● Configure an anycast gateway MAC address.
OS10(config)# ip virtual-router mac-address 00:01:01:01:01:01
● Configure routing on the virtual network.
OS10(config)# interface virtual-network 10000
OS10(conf-if-vn-10000)# ip vrf forwarding tenant1
OS10(conf-if-vn-10000)# ip address 10.1.0.231/16
OS10(conf-if-vn-10000)# ip virtual-router address 10.1.0.100
OS10(conf-if-vn-10000)# no shutdown
OS10(conf-if-vn-10000)# exit
12. Configure symmetric IRB.
● In EVPN mode, configure the router MAC address that is used by remote VTEPs as the destination address in VXLAN
encapsulated packets that are sent to the switch. Configure a dedicated VXLAN VNI for symmetric IRB for each tenant
VRF.
OS10(config)# evpn
OS10(config-evpn)# router-mac 00:01:02:03:04:05
OS10(config-evpn)# vrf tenant1
OS10((config-evpn-vrf-tenant1))# vni 3000
OS10((config-evpn-vrf-tenant1))# route-target auto
OS10((config-evpn-vrf-tenant1))# exit
OS10(config-evpn)# exit
13. Configure advertisement of the connected networks through EVPN Type-5 routes.
OS10(config)# evpn
OS10(config-evpn)# vrf tenant1
OS10((config-evpn-vrf-tenant1))# advertise ipv4 connected
OS10((config-evpn-vrf-tenant1))# exit
VTEP Leaf Switch 2 configuration
1. Configure a loopback interface for the VXLAN underlay using the same IP address as the VLT peer.
OS10(config)# interface loopback0
OS10(conf-if-lo-0)# no shutdown
OS10(conf-if-lo-0)# ip address 192.168.1.1/32
OS10(conf-if-lo-0)# exit
