■目的 Arista-SWでVRFの設定をしてみる。
基本的にCiscoと同じ設定なので備忘録として記載する。
■内容以下コマンドでVRF設定が可能
①まずはvrfの定義をする
vrf definition vrf1
rd 65000:1
vrf definition vrf2
rd 65000:2
②インターフェースVLANにVRFの指定をする
interface Vlan301
vrf forwarding vrf1
ip address 30.0.1.254/24
interface Vlan401
vrf forwarding vrf2
ip address 40.0.1.254/24
③VRF指定でルーティングを記載する
ip route vrf vrf1 40.0.1.0/24 30.0.2.1
ip route vrf vrf2 30.0.1.0/24 40.0.12.1
④IProutingでvrfの指定をする
ip routing
ip routing vrf vrf1
ip routing vrf vrf2
①Arista#sh vrf
Vrf RD Protocols State Interfaces
