IP Setup 7-37
• Monitor WAN – Toggle this option to Ye s (the default) to enable VRRP routers on the interface to relinquish
Master status if the WAN connection is down. If you do not want the VRRP routers to relinquish Master
status, toggle this option to No. Also see “VRRP Options (WAN Link Failure Detection)” on page 2-26 for
more information.
• Serve/Relay DHCP only if Virtual Router in Master state – If you toggle this setting to Ye s, the router will
stop DHCP services if Virtual Routers have been configured on the interface, and no Virtual Router is in
Master state. Toggling this to No (the default) will sustain DHCP services even if there is no Virtual Router
in Master state.
• DHCP Gateway IP Address – This field allows you to enter a Virtual IP address. Entering a Virtual IP
address causes the router to serve the Virtual IP address as the DHCP gateway and server IP instead of
the configured DHCP gateway on the interface. This behavior only happens if the Virtual Router associated
with the configured DHCP gateway address is in Master state.
