7. (Optional) For advertising leaked routes from Yellow VRF only to an external router on the default VRF and not to an
underlay network, use route-maps on spine-facing eBGP neighbors and also on the iBGP neighbor between the VLT peers.

Leaf 4 configuration
1. Configure VRFs Yellow, Green, and Red.
OS10(config)# ip vrf Yellow
OS10(conf-vrf)# exit
OS10(config)# ip vrf Green
OS10(conf-vrf)# exit
OS10(config)# ip vrf Red
OS10(conf-vrf)# exit
2. Configure Layer 3 virtual-network interfaces with VRFs and IP addresses.
OS10(config)# interface virtual-network 10001
OS10(conf-if-vn-10001)# ip vrf forwarding Yellow
OS10(conf-if-vn-10001)# ip address 10.1.0.4/24
OS10(conf-if-vn-10001)# ip virtual-router address 10.1.0.254
OS10(conf-if-vn-10001)#
OS10(config)# interface virtual-network 30001
OS10(conf-if-vn-30001)# ip vrf forwarding Red
OS10(conf-if-vn-30001)# ip address 10.3.0.2/24
OS10(conf-if-vn-30001)# ip virtual-router address 10.3.0.254
3. Configure EVPN with IP-VRFs.
OS10(config)# evpn
OS10(config-evpn)# auto-evi
OS10(config-evpn)# disable-rt-asn
OS10(config-evpn)# vrf Yellow
OS10(config-evpn-vrf-Yellow)# vni 65001
OS10(config-evpn-vrf-Yellow)# route-target auto
OS10(config-evpn-vrf-Yellow)# advertise ipv4 connected
OS10(config-evpn-vrf-Yellow)# exit
OS10(config-evpn)# vrf Green
