网友1：
能相互ping通吗？？ospf路由都学习到了吗？
ospf的邻居状态和bgp邻居的状态都是什么
楼主：
都能PING 通,OSPF 的状态是FULL,BGP邻居状态是ACTIVE
奇怪的是DEBUG任何东西都没有东西显示出来
网友2：
如何收集MSR设备的debug信息？
A：
debug是设备调试，排错中非常重要也非常有效的手段。需要对网络协议和H3C产品相对熟悉的情况下使用。
【操作步骤】
无论使用console配置、还是使用远程telnet，都只需要输入:
<H3C> terminal monitor
<H3C> terminal debugging
此处以调试链路层协议ppp数据包为例
<H3C>debugging ppp all
【提示】
1、可以从display debug看出现在有哪些调试开关是打开的
2、调试开关打开,对路由器性能会有相应程度的影响,所以用后请及时关闭调试信息:
<H3C>undo debug all,或者ctrl+o亦可
楼主：
已经看到DEBUG信息了,如下
Z02-RT-2040-01
*Mar 15 10:09:45:425 2007 Z02-RT-2040-01 RM/6/RMDEBUG:

另外问一下这个版本支持MPLS 吗?好象没有命令

网友3：
建议配置ebgp时指定peer地址用物理接口地址不要用loopback地址
请修改配置测试
Version 5.20, Beta 1204P03, Basic
基本版本不支持mpls
需要申请软件版本
还有ospf是区域内路由协议，您怎么在ebgp间也运行ospf？？？
给您发个典型的配置实例您看一下吧
BGP路由协议典型配置

【需求】
RouterA和RouterB之间运行IBGP，Router B和Router C之间运行EBGP。
