AristaでのVRF設定

■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

■終わり

Ciscoとほぼ一緒

私の体験が誰かの生産性向上に役立っていただけることを祈って
