2024年11月3日 (日) 12:05時点における版

Nexus で採用され Catalyst 9000 から実装された GIR について、機能検証を実施しました。

このページにラボシナリオとして、コンフィグや確認コマンド、疎通確認のポイントなどをまとめています。

検証対象として Catalyst 9000V Q200 を使用していますが、実機の Catalyst 9000 シリーズでも同様の動作をするはずです。

目的

GIR の動作について理解を深められること。

通信要件

GIR : BGP / OSPF / HSRP

GIR を開始したホストを経路迂回すること
GIR を停止したホストに経路復旧すること

検証環境

Cisco Catalyst 9000V Q200 : IOS-XE 17.12.1 x6

構成図

Catalyst 3850 : PE01 , CE01 , CE02 , CORE01 , CORE02 , CPE01

PE01 を WAN の機器、CE01 , CE02 , CORE01 , CORE02 , CPE を LAN の機器とする。
