ASR9000 nV satellite (Dual-Home)

2019-11-26 | No comments

ASR9K 有两种虚拟化的技术，一种为nV edge，也叫nV cluster，属于将两个ASR9K的机箱虚拟化成一个路由器，使用统一的控制层面，类似于CRS中的多机(5.3.4 以后开始就不再支持该feature,link)；另一种为nV satellite，这种技术是为了扩展9K上GigabitEthernet接口，通过ASR9K外接一个ASR 9000v来实现（或者901，903），其中一个9000v上包含40+ Gi的下行接口，4个TenG的上行接口。

以下介绍nV satellite Dual-Home的一个配置，即一个9000v上行连接两个ASR9K，并为两个ASR9K配置不同的优先级，使同一时间只有一个ASR9K为active role，参与流量转发的，另一台为standby。

Upgrade nV Satellite

需要为ASR9000安装9000v的PIE
升级会使9000v重启

升级Guide

Note

双宿的时候，standby ASR9000上连接到9000v的接口会处于up/down的状态，不转发流量。
