mGRE(Multipoint Generic Routing Encapsulation,多点通用路由封装)是一种基于NHRP(Next Hop Resolution Protocol,下一跳地址解析协议)的动态VPN技术。 在普通的VPN网络(如GRE)中,隧道是静态的,需要管理员手动建立,无法利用公网地址动态建立,配置和维护的工作量巨大,扩展性差。 在mGRE网络中,NHRP用来实现网络分支节点的...

一、DMv*n简述 DMv*n(Dynamic Multipoint v*n)是通过多点GRE(MGRE)和下一跳解析协议(NHRP)与IPSec相结合实现的解决方案。 (1) DMv*n的特点,包括: A、Dynamic Multipoint v*n,高扩展性v*n解决方案 B、简单的Hub和Spoke配置提供了Full meshed连通性 C、支持Spoke动态地址 D、增加新的Spoke无须... ...
An mGRE tunnel interface is a point-to-multipoint virtual interface used in Dynamic Smart VPN (DSVPN) applications, and has the source address, destination address, and tunnel interface IP address. The destination IP address of a GRE tunnel interface is manually configured, whereas the destination...
Dynamic (Hub Side) Multipoint Generic Routing Encapsulation (mGRE) Tunnels: The next type of GRE configuration uses mGRE at the hub site (R1 in this case) and normal point-to-point GRE configuration at the spokes. There are two main ways that this can be configured but before jumping int...
A GRE tunnel in decapsulation mode has only tunnel source configured, without any tunnel destination address. This decapsulated GRE tunnel behaves like a P2MP (Point-to-multipoint) tunnel, which means that an incoming GRE packet can have any source IP address and ...
