思科设备部署运营商架构-ipv6+isis+bgp配置实战

1.            实验拓扑:

使用GNS3(版本0.8.6+c3725-adventerprisek9-mz.124-15.T5.bin

wKiom1VKxe7iAR-ZAAEv5ciBXyE229.jpg

2.            实验需求:

  A.       通过IPV6技术部署

  B.       省干通过ISIS协议将AS内部的直连口和环回口路由通告

  C.       通过路由反射器实现省内、市内业务路由互传

  D.      国干通过OSPF协议将AS内部的直连口和环回口路由通告

  E.       通过EBGP协议实现省干与国干路由互传
