Catalyst3550とCatalyst2950でVLANをMHSRP、STP(mode mst)、EtherChannelを用いて冗長化して構成する
デフォルトGW 192.168.11.1、各VLAN間の通信制限なし。
VLAN10 192.168.12.0/24
->2950をEtherChannelで接続し冗長化。STP&Trunkにて経路断の冗長化。
サーバはbonding(alb)で別々の2950に接続。
VLAN20 192.168.13.0/24
->2950をEtherChannelで接続し冗長化。STP&Trunkにて経路断の冗長化。
サーバはbonding(alb)で別々の2950に接続。
VLAN30 192.168.14.0/24
->2950の接続なし、3550だけで構成。Trunkにて経路断の冗長化。
サーバはbonding(alb)で別々の3550に接続。
