Router1

  • LAN1:192.168.100.1
  • バーチャルIP:192.168.100.254
  • WAN:LAN2
ip route default gateway dhcp lan2
ip lan1 address 192.168.100.1/24
ip lan1 vrrp 1 192.168.100.254 priority=200
ip lan1 vrrp shutdown trigger 1 lan2
ip lan2 address dhcp
ip lan2 nat descriptor 1
nat descriptor type 1 masquerade
nat descriptor address outer 1 primary

 

Router2

  • LAN1:192.168.100.2
  • バーチャルIP:192.168.100.254
  • WAN:LAN2
ip route default gateway dhcp lan2
ip lan1 address 192.168.100.2/24
ip lan1 vrrp 1 192.168.100.254 priority=100
ip lan1 vrrp shutdown trigger 1 lan2
ip lan2 address dhcp
ip lan2 nat descriptor 1
nat descriptor type 1 masquerade
nat descriptor address outer 1 primary

 

 

クライアントPC

  • IP:192.168.100.51
  • ネットマスク:255.255.255.0
  • デフォルトゲートウェイ:192.168.100.254
  • DNS1:192.168.11.254
  • DNS2:8.8.8.8

デフォルトゲートウェイにバーチャルIPを設定してあげるのがポイントです。
