BGP Community只是BGP路由可以携带的一种属性,是BGP中的一个可选可传递属性(Optional Transitive),所以可以选择为路由配置Community,也可以不配,如果配置,Community需要明确要求BGP路由器保留和传递该属性,否则邻居收不到路由的Community属性。 都知道Peer Group是用来简化BGP邻居配置的,而BGP Community则可以简化BGP路由在...

A VPN target is a BGP extended community attribute. It is used to control the receiving and advertisement of VPN routing information. A maximum of eight VPN targets can be configured using avpn-targetcommand. (Optional) Restrict the number of routes in a VRF. ...
The extended community attribute carries the tunnel type (VXLAN tunnel), and the Next_Hop attribute carries the local VTEP IP address. After Leaf2 receives the BGP EVPN route from Leaf1, Leaf2 processes the route as follows: If the ERT carried in the route is the same as the IRT of ...
