以下关于MPLS BGP VPN路由信息的发布描述正确的有()A、PE和CE之间运行普通的IGP路由协议或者BGP协议交换VPN用户IPv4路由信息B、PE通过MP-BGP将VPN用户VPNv4路由信息发布给对端PEC、对端PE根据RT决定是否将通过MP-BGP学习到的路由信息注入相应的VRFD、对端CE通过普通IGP路由协议或者BGP路由协议从所连接PE学习路由信息
MPLS BGP VPN中,传统OSPF-BGP引入办法使得VPN用户Site的OSPF内部路由传递到对端后,对端Site会将其作为OSPF外部路由处理,不便于实现Stub区域和路由集合。OSPF超级Backbone模型如何克服这个问题()。A、不同的路由类型使用不同的RDB、OSPF配置时给每条路由分配不同的路由类型C、使用BGP扩展团体属性传递OSPF路由类型信息D、使用BGP MED属性传递OSPF路由类型
MPLS BGP VPN中,VPN用户路由信息是如何在公网上传递的()。A、LDP用来在公网上传递VPN用户路由信息B、IBGP用来在公网上传递VPN用户路由信息C、OSPF用来在公网上传递VPN用户路由信息D、MP-BGP用来在公网上传递VPN用户路由信息
Which two steps are required for a Kompella Layer 2 VPN?()A、Configure a siteid for each ce.B、Configure a VPN label for each VPN.C、Configure a MP-bgp session to each pe.D、Configure an Extended LDP Session to each pe.
下列关于RT的Export Target属性和Import Target属性的描述正确的是()。A、PE接受到MP-BGP路由时,将路由协议中所携带的RT属性与本地VPN的Import Target属性比较,存在交集的才能被接收到该VPNB、PE接受到MP-BGP路由时,将路由协议中所携带的RT属性与本地VPN的Export Target属性比较,存在交集的才能被接收到该VPNC、本地VPN的私网路由通过MP-BGP路由协议发布给对端PE时,在BGP路由中需要携带该VPN的Export Target属性D、本地VPN的私网路由通过MP-BGP路由协议发布给对端PE时,在BGP路由中需要携带该VPN的Importt Target属性Import
MP-BGP协议相对于BGP协议的改动包括()。A、新增MP REACH NLRI属性B、新增MP UNREACH NLRI属性C、新增Extended Communities属性D、新增VPNv4地址族
下列关于MPLS-VPN的描述中,哪些说法是错误的()A、RD属性是利用BGP的MP_UNREACH_NLRI扩展属性,将每个VPN出口的路由由IPV4路由变成VPNV4路由B、MPLS私网标签是由PE的BGP协议进行分发的,它对每一条的VPNV4路由分发一个随机的私网标签,一一对应,不许重复C、MPLS私网标签是由PE针对VPNV4路由所分发的,且VPNV4路由是由RD+IPV4路由所组成的,也就是说不同的私网标签其本质是RD的不同D、MPLS-VPN的RT属性是使用BGP-4的Extended_Communities属性,它在BGP邻居建立时,已经作为协商属性之一,向所有邻居进行了宣告
