哪位兄台知道关于 BGP 配置的文章？？

天作孽，犹可违；自作孽，不可活出自于《孟子·离娄章句》《书经·太甲篇》这十二字的意思是说上天降下的灾祸，还可以逃脱；自己造成的灾祸，那就活不成了。
少年中国说/梁启超
（一九○○年二月十日）
日本人之称我中国也，一则曰老大帝国，再则曰老大帝国。是语也，盖袭译欧西人之言也。呜呼！我中国其果老大矣乎？梁启超曰：恶是何言，是何言，吾心目中有一少年中国在！
欲言国之老少，请先言人之老少。老年人常思既往，少年人常思将来。惟思既往也，故生留恋心；惟思将来也，故生希望心。惟留恋也，故保守；惟希望也，故进取。惟保守也，故永旧；惟进取也，故日新。惟思既往也，事事皆其所已经者，故惟知照例；惟思将来也，事事皆其所未经者，故常敢破格。老年人常多忧虑，少年人常好行乐。惟多忧也，故灰心；惟行乐也，故盛气。惟灰心也，故怯懦；惟盛气也，故豪壮。惟怯懦也，故苟且；惟豪壮也，故冒险。惟苟且也，故能灭世界；惟冒险也，故能造世界。老年人常厌事，少年人常喜事。惟厌事也，故常觉一切事无可为者；惟好事也，故常觉一切事无不可为者。老年人如夕照，少年人如朝阳；老年人如瘠牛，少年人如乳虎；老年人如僧，少年人如侠；老年人如字典，少年人如戏文；老年人如鸦片烟，少年人如泼兰地酒；老年人如别行星之陨石，少年人如大洋海之珊瑚岛；老年人如埃及沙漠之金字塔，少年人如西伯利亚之铁路；老年人如秋后之柳，少年人如春前之草；老年人如死海之潴为泽，少年人如长江之初发源。此老年与少年性格不同之大略也。梁启超曰：人固有之，国亦宜然。
Cisco的4908-l3的配置比较繁杂，通过IRB来实现不同桥接组之间的通讯 可以与trunk互连 但是，要对每个单独的桥接组进行封装。本实例中主要介绍在一个基于4908为中心，3500为二级交换机的园区网方案设计以及每个设备的调试过程等。着重介绍4908的配置过程 至于3500的配置请见 基本配置栏目中 关于 3500全系列配置的文章。在此，不赘述！
至于vlan分配等，通过基本配置自己体会吧 呵呵！

对物理端口不做配置，通过子接口进行封装。从下面对子接口的封装可以看出G1下面有三个bridge group (1、40、50)

上述的br-group有点象 VLAN的划分过程
以下是对每个br-group 加上网关（可以这样理解）
interface BVI1

就可以了
Center_A#
不过不能通过4908实现 VTP server client的配置！
只能通过透明传输 不过 对于二级的堆叠组可以局域实现 server client的配置

大姣头孢： 1.说明Cisco的4908-l3的配置比较繁杂,通过IRB来实现不同桥接组之间的通讯 可以与trunk互连 但是,要对每个单独的桥接组进行封装.本实例中主要介绍在一个基于4908为中心,3500为二级交换机的园区网方案设计以及每个设备的...
长垣县15575818823： BGP 属性选路, 很想知道去往对端EBGP选路用哪个, 去往iBGP选路用哪个, 双上链用哪个属性? - ？
大姣头孢： 当配置IBGP对等体关系时,要配置next-hop-self.因为BGP一般不修改条目携带的路径属性,若本端从EBGP对等体先学到路由,然后该路由由本端传到自己的IBGP对等体,则不使用next-hop-self会使本端的IBGP对等体无法与本端的EBGP对等...
长垣县15575818823： BGP同步的问题 - ？
大姣头孢： 这是BGP路由的原则之一,当前对同步使用已经很少. 原则: 从IBGP学习到的路由是否给EBGP,要看IGP和BGP的同步状态.同步是BGP路由和IGP路由条目达到一致的状态.即BGP路由表和IGP路由表中都有些路由信息.才向EBGP邻居...

长垣县15575818823： 四级书上讲了BGP,但是有个课后题说自治系统之间的路由选择协议是域间路由选择协议,不是外部网关协议呢? - ？
大姣头孢： 所为域间路由选择协议,就是指BGP协议,这里的域间是指AS之间,不是ospf的area之间.bgp是惟一的AS间的路由...
长垣县15575818823： 有哪位兄台知道被路由协议的作用?它和路由协议有什么关系? - ？
大姣头孢： 被路由协议是一些用于定义数据报内字段格式并且为用户的通讯传输提供一种机制的协议(也就是网 络层地址中提供了足够的信息使得数据包能够根据编制方从一个主机传递到另一个主机的任何网络协 议)议的数据报可以被路由器转发到其他网络 被路由协议使用路由协议来寻址和转发数据包
