因此双方至少有一个靠明细路由指向对方才能建立peer Loop Prevention EBGP Loop Prevention 说到BGP的防环,就得提到一个well-known属性——AS_Path 简单来说,每一个AS发出路由,AS_Path就会记录下当前发送者AS号 如果记录AS号时发现已经记录过了,那就说明出现了环路 AS_Path可在路由表里查看 IBGP Loop Prevention E...

since the originator attribute of the route is different, loop prevention is not triggered, but the control plane routing loop does not form because the OMP route is not installed into the RIB. This is because the OMP route
Examples of Recommended Configuration to Prevent Routing Loops Setting a Proper Local_Pref Value for Loop Prevention Configuration roadmap: Apply an import policy on DeviceB to increase the Local_Pref value of the BGP route received from DeviceA to 110. As the default Local_Pref value of the ...
Because of the loop prevention mechanism, R2 for instance will have to reject R1 prefixes because it can see its own AS in the AS_PATH attribute. To solve this we can use one of two solutions: 1-Customer side solution (in R1,R2 use Allows-in) ...

(3) 动态路由:由路由协议(routing protocol)动态建立的路由(比如:rip.ospf,bgp,eigrp,egp,is-is) 静态路由的缺点是不能动态反映网络拓扑,当网络拓扑发生变化时,管理员就必须手工改变路由表;然而静态路不会占用路由器太多的 CPU 和RAM 资源,也不占用线路的带宽。如果出于安全的考虑想隐藏网络的某些部分或者管理员...
Use this command to forward packets over multiple paths. User can control the maximum number of parallel eBGP routes that can be installed in a routing table. Enabling multipath does not affect the best path selection in BGP. If multipath is enabled, all the path...
