2013年10月3日 · Auto-Summary in the EIGRP process will summarise your networks as they cross classful bondaries. So when your 10.x.x.x loopbacks cross a classful boundary (the serial interface 172.16.xx.xx) they become back to there classful summary - 10.0.0.0/8.

2014年11月24日 · By default, hello packets are sent every 5 seconds. The exception is on low-speed, nonbroadcast multiaccess (NBMA) media, where the default hello interval is 60 seconds. Low speed is considered to be a rate of T1 or slower, as specified with the bandwidth interface configuration command. The default hello interval remains 5 seconds for high ...

2013年4月2日 · Currently am reading on EIGRP over NBMA network (precisley frame-relay) and cannot understand the concept of "broadcast" statement at the end of "frame-relay map ip address dlci number broadcast " command line. As far as my understanding is, is that its like EIGRP package the EIGRP Multicast address in a unicast address.

2005年8月10日 · It is particularly critical to configure nonbroadcast multi-access (NBMA) interfaces correctly, because otherwise many EIGRP packets may be lost in the switched network. There are three basic rules: The traffic that EIGRP is allowed to send on a single virtual circuit (VC) cannot exceed the capacity of that VC.

EIGRP Over NBMA is a form of EIGRP configuration. 1) Configure EIGRP with AS 25. 2) Each router should make summarization to decrease the routing table. 3) Make the configuration for that EIGRP uses %30 more bandwith due to default config. ( On the serial interface of the HO router ). 4) Enable authentication on all EIGRP routers using the ...

2011年12月13日 · EIGRP是作为比较老的内部网关路由协议（Interior Gateway RoutingProtocol，IGRP）的增强版本进行开发的，与高级内部网关协议有许多相同的特点，比如高速收敛、部分更新以及支持多个网络层协议的能力。 万字长篇详解

2012年6月19日 · I am studying my first lessons on CCNP. I started with EIGRP and now configuring it over a Frame-Relay network. Platform: three c3660 routers in GNS3 environment; Topology: Hub-and-Spoke; Strategy: Multipoint with sub-interface s1/0.1 configured; psudo broadcasts have been configured via frame-relay map ip A.B.C.D xyz broadcast command.

2018年11月1日 · nnbma（非广播多路访问网络）是ospf（开放最短路径优先）通信协议中四种网络的一种。nbma用于精确模型x.25和帧中继环境，这些模型不具备内部广播和多 点传送能力。其他的ospf网络类型有：广播、点对点和点对多点。

2019年11月5日 · 本文档详细记录了一次NBMA（非广播多路访问）网络的实验过程，包括基础配置、IP地址划分、配置路由器接口、建立到ISP的缺省路由、实施MGRE隧道、配置EIGRP进行路由学习，以及NAT转换和CHAP认证等步骤，旨在实现网络的正常运行和安全连接。 取出五个 路由器。 对五个路由器进行基础配置。 文章浏览阅读216次。 本文档详细记录了一次NBMA（非广播多路访问）网络的实验过程，包括基础配置、IP地址划分、配置路由器接口、建立到ISP的缺省 …

2010年11月9日 · For some NBMA networks (such as frame relay) CISCO has added in a command to allow the router to forward the broadcasts over the link. It does this by sending a copy of the multicast/broadcast packet to each neighbouring router.
