vxlan: T5753: add support for VNI filtering
In a service provider network a service provider typically supports multiple bridge domains with overlapping vlans. One bridge domain per customer. Vlans in each bridge domain are mapped to globally unique VXLAN VNI ranges assigned to each customer. Without the ability of VNI filtering, we can not provide VXLAN tunnels with multiple tenants all requiring e.g. VLAN 10. To Test: set interfaces vxlan vxlan987 parameters external set interfaces vxlan vxlan987 source-interface eth0 set interfaces vxlan vxlan987 parameters vni-filter set interfaces vxlan vxlan987 vlan-to-vni 50 vni 10050 set interfaces vxlan vxlan987 vlan-to-vni 51 vni 10051 set interfaces vxlan vxlan987 vlan-to-vni 52 vni 10052 set interfaces vxlan vxlan987 vlan-to-vni 53 vni 10053 set interfaces vxlan vxlan987 vlan-to-vni 54 vni 10054 set interfaces vxlan vxlan987 vlan-to-vni 60 vni 10060 set interfaces vxlan vxlan987 vlan-to-vni 69 vni 10069 set interfaces bridge br0 member interface vxlan987 Add new op-mode command: show bridge vni Interface VNI ----------- ----------- vxlan987 10050-10054 vxlan987 10060 vxlan987 10069
