问题描述：

一台MSR36-40路由，用于业务接入，CE设备，通过2M线接入国家电网调度数据专网。

按甲方接入方式要求，只允许从OSPF获取路由，不允许从BGP获取，这是强制要求，只能无条件服从。

我做的配置如下：

从目前学到的路由来看，还是有BGP协议，BGP路由。

现在问题是：

我的OSPF配置和BGP配置是否有误？若有问题，应该如何修改？最终要求是仅使用OSPF获取路由，不允许BGP协议学习路由。

目前配置BGP的目的是保证私网联通。

bgp 25513

group ibgp-peer internal

peer ibgp-peer connect-interface LoopBack0

peer 55.2.40.2 group ibgp-peer

peer 55.2.40.5 group ibgp-peer

address-family ipv4 unicast

import-route direct

peer ibgp-peer enable

address-family vpnv4

peer ibgp-peer enable

ip vpn-instance vpn-nrt

address-family ipv4 unicast

import-route direct

ip vpn-instance vpn-rt

address-family ipv4 unicast

import-route direct

这一段是否应该删除IPV4相关的配置？

烦请举例，谢谢！

BGP这段是否可以这样写？这样写能否达到相关要求？

bgp 25513

group ibgp-peer internal

peer ibgp-peer connect-interface LoopBack0

peer 55.2.40.2 group ibgp-peer

peer 55.2.40.5 group ibgp-peer

ipv4-family vpnv4

peer 55.2.40.2 enable

peer 55.2.40.2 advertise-community

peer 55.2.40.2 reflect-client

peer 55.2.40.5 enable

peer 55.2.40.5 advertise-community

peer 55.2.40.5 reflect-client

peer ibgp-peer enable

peer ibgp-peer reflect-client

之前提出问题，“吃巧克力会死”工程师回复：

“这是一个PE设备吧，BGP学习到的几个路由应该是对端在BGP里面import的其他路由或者是network的，这种情况要想不从BGP学，反而从OSPF学习的花，在OSPF里面引入BGP就行了呀，不过还是没理解为什么这样做

”

我比较菜，刚学习网络，请教，应该如何写命令？能否举例说明？谢谢。

最佳答案

额我说的在OSPF视图下引入下BGP 。即：import route bgp 。另外这个应该是PE吧，如果是CE怎么还有MPLS配置，是PE就该把BGP里面的路由引入IGP ，但我看OSPF并没有绑定VPN实例，反而直连的接口绑定了VPN实例，如果确定要让从BGP里学习到的路由从OSPF学习到，就按照我说的引入就行

确定只能通过OSPF学习到。按您的指导，应该是在OSPF里绑定VPN实例，而不是在直连接口绑定吗？
