API Guide
Configure iBGP IPv4 peering between the VLT peers
OS10(config)# router bgp 100
OS10(config-router-bgp-100)# neighbor 172.16.250.10
OS10(config-router-neighbor)# remote-as 100
OS10(config-router-neighbor)# no shutdown
OS10(config-router-neighbor)# exit
OS10(config-router-bgp-100)# exit
14. 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 20000
OS10(conf-if-vn-20000)# ip vrf forwarding tenant1
OS10(conf-if-vn-20000)# ip address 10.2.0.234/16
OS10(conf-if-vn-20000)# ip virtual-router address 10.2.0.100
OS10(conf-if-vn-20000)# no shutdown
OS10(conf-if-vn-20000)# exit
15. Configure symmetric IRB
In EVPN mode, configure the router MAC used by remote VTEPs as the destination address in VXLAN encapsulated packets sent to the
switch. Configure a dedicated VXLAN VNI for symmetric IRB for each tenant VRF.
OS10(config)# evpn
OS10(config-evpn)# router-mac 00:01:02:03:04:06
OS10(config-evpn)# vrf tenant1
OS10(config-evpn-vrf-tenant1)# vni 3000
OS10(config-evpn-vrf-tenant1)# route-target 65535:30000 both
OS10(config-evpn-vrf-tenant1)# exit
OS10(config-evpn)# exit
OS10(config)#
16. Configure an externally connected VLAN
OS10(conf)# interface vlan 200
OS10(conf-if-vlan)# ip vrf forwarding tenant1
OS10(conf-if-vlan)# ip address 10.10.0.2/16
OS10(conf-if-vlan)# no shutdown
OS10(conf-if-vlan)# exit
OS10(conf)# interface ethernet 1/1/7
OS10(conf-if-eth1/1/7)# switchport mode trunk
OS10(conf-if-eth1/1/7)# switchport trunk allowed vlan 200
17. Configure advertisement of the connected networks via 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
18. Configure BGP session with external router on the border-leaf VTEPs
OS10(config)# router bgp 100
OS10(config-router-bgp-100)# vrf tenant1
OS10(config-router-bgp-100-vrf)# neighbor 10.10.0.3
OS10(config-router-vrf-neighbor)# remote-as 102
