Maipu –TRACK / RTR WITH VRRP

To run VRRP in Local LAN , Last mile (Wan Link) is Fast Ethernet with Maipu routers.

Description : TRACK / RTR function is used to track remote server IP from Master router, as the link down the track function will detect the server status is unavailable, It will reduce VRRP priority by 20, In result Master will become backup. Backup will change to Master.

As the link restored, the highest priority will become master.

This solution is recommended for Wan terminated on FastEthernet, Since Fast Ethernet interface link status will is not down every time in link failure.
