1 VXLAN EVPN Automation with ODL NIC Presented by: Shreyans Desai, Serro Yrineu Rodrigues, Lumina Networks

2 Agenda Use-Case - Why we are doing this? What is VXLAN / EVPN? Define VXLAN, BGP and EVPN configuration manually on Junos Automate for deployment at scale Define VXLAN, EVPN, assign VLANs to interfaces using ODL-NIC Demo (of Automating Deployment at scale)

3 Use-Case - Why we are doing this? Per-Device templatized manual configuration consumes time Pushing configs for 10 or 20 Top of Rack Leaf switches is fine 100+ rack data center - with 10 hypervisors per rack, with each running 10+ VMs each Get me some automation!

4 VXLAN Virtual Extensible LAN - Expands the 4096 VLANs into 16 million possible unique VXLANs (24-bit network ID) Useful for large cloud deployments, distributed over Data Centers Allows Layer-2 adjacency by extending L2 domain across IP networks Run as an overlay on IP networks Endpoints are called VTEPs (VXLAN Tunnel Endpoints)

5 EVPN Ethernet VPN is the control plane used for signalling VXLAN traffic An address family in Multiprotocol BGP (MP-BGP) MAC addresses are quickly relearnt when VMs are moved - Preventing any Ghosting of MAC Addresses The L3 gateway is all aware of the whole network - Translating MAC Address tables to ARP entries The routing decision can be taken on Layer 2 or on Layer 3, because the gateway is fully aware of ARP entries

6 Junos Manual Configuration - VXLAN On Spines & Leafs [edit vlans] user@hostname# show Server_Mgmt vlan-id 101; l3-interface irb.101; vxlan vni 101; ingress-node-replication; On Spines only - Distributed Gateway [edit interfaces] user@hostname# show irb.101 proxy-macip-advertisement; family inet address /22 preferred; virtual-gateway-address ; virtual-gateway-v4-mac 00:01:01:11:01:01;

7 Junos Manual Configuration - BGP [edit protocols bgp] user@hostname# show group DC_Leafs type internal; local-address ; family evpn signaling; cluster ; neighbor ; < truncated > neighbor ;...Continued group Spine_to_Spine type internal; family evpn signaling; neighbor ; neighbor ;

8 Junos Manual Configuration - EVPN Signalling [edit protocols] user@hostname# show evpn encapsulation vxlan; extended-vni-list [ 101 truncated 130 ]; multicast-mode ingress-replication; default-gateway no-gateway-community; vni-options vni 101; truncated vni 130; [edit policy-options] user@hostname# show community vni0101 members target:10000:101; truncated community vni0130 members target:10000:130; [edit switch-options] shreyans@hostname# show vtep-source-interface lo0.0; route-distinguisher :1; vrf-target target:65000:2;

9 Intent-Based solution - Setup EVPN on Junos URL: "switch-info:switch-info": [ "switch-info:name": "Server Switch", "switch-info:device-function": "LEAF", "switch-info:loopback-ip": " ", "switch-info:http-ip": " ", "switch-info:http-port": "3000", "switch-info:http-user": "serro", "switch-info:http-password": "p@ssw0rd" ] URL: "host-info:host-info": [ "host-info:host-name": "Server01", "host-info:switch-name": "Server Switch", "host-info:ip-address": " ", "host-info:subnet-mask": " ", "host-info:gateway-ip": " ", "host-info:host-interfaces": [ "host-info:interface-name": "eth1", "host-info:switch-interface": "xe-0/0/2", "host-info:bridges": [ "host-info:bridge-name": "eth1.101", "host-info:vlan-name": "admin", "host-info:vlan-id": "101"...

10 Intent-Based solution - Setup EVPN on Junos URL: ntent-evpn/intent_a "intent-evpn:evpn-services": [ "intent-evpn:service-name": "Service A", "intent-evpn:vlan-name": "admin" ] URL: ent-state-transactions "intent-state-transactions": "intent-state-transaction": [ "intent-id": "ED1c03aC-6eBD-63be-44E3-5Bfdb09bfBF2", "deploy-attempts": 2, "received-event": "INTENT_DISABLED", "current-state": "DEPLOYED", "undeploy-attempts": 3 ]

11 Intent-Based solution - Setup EVPN on Junos URL: "service-mapping": [ "id": "service-101_k8s-fed-node", "hostname": "k8s-fed-node", "hostbridge": "eth1.101", "servicename": "service-101", "subnetmask": " ", "vlanid": 101, "hostinterface": "eth1", "podip": " ", "podgatewayip": " " ]
