ADcampus方案通过vpn-default出外网的配置指导

ADcampus方案

1.创建vlan 接口用于与spine上行设备互联；

vlan 50

#

interface Vlan-interface50

ip binding vpn-instance vpn-default

ip address 10.1.254.252 255.255.255.0

2.在Spine设备上配置缺省静态路由，并引入到BGP的vpn-default，让leaf设备学习到该缺省路由

#

ip route-static vpn-instance vpn-default 0.0.0.0 0 10.1.254.253                      //10.1.254.253为spine上行对端互联地址

#

bgp 100

non-stop-routing

router-id 10.0.0.254

peer 10.0.0.253 as-number 100

peer 10.0.0.253 connect-interface LoopBack0

#

address-family l2vpn evpn

  reflector cluster-id 10.0.0.254

  undo policy vpn-target

  peer 10.0.0.253 enable

  peer 10.0.0.253 reflect-client

#

ip vpn-instance vpn-default

  #

  address-family ipv4 unicast

   default-route imported

   import-route direct

   import-route static

3. 在Spine上行设备配置回程路由。
