ip vrf receive 这个参数其实用的很少，它和forwarding 最大的区别在于：如果你在一个三层接口上使用了forwarding，那么这个这个三层接口的IP 地址就被完全放进了你forwarding 的那个Vrf。而如果在三层接口上使用的参数是 receive，那么这个接口上的IP地址仍在还会在global的路由表里出现。

BGP/MPLS IP VPN为每个VPN进行实例化,构建本VPN私有转发信息实例,即VPN实例(VPN-instance)。VPN实例也称为VPN路由转发表VRF(VPN Routing and Forwarding table)。 VPN实例用于将VPN私网路由与公网路由隔离。不同VPN实例的路由之间也是相互隔离的。在所有BGP/MPLS IP VPN组网方案中,都需要配置VPN实例。

I have set ip helper-address "DHCP IP" in this SVI, before the update it was working without problems but after the reboot is not forwarding nothing. If I configure ip helper in a access switch it works. Any idea? Thank you for your help. I have this problem too Labels: Catalyst...
