Route Health Injection
The alias IP is very important because it is the IP that the CSM instructs the MSFC to use as the next-hop
to reach the advertised virtual server

vlan 221
# By default, a virtual server listens to traffic coming in on any VLAN. You can restrict
# access to a virtual server by defining a specific VLAN. When using Route Health
# Injection, it is required to specify the VLAN for the virtual server. This tells the CSM
# which next-hop it needs to program in the static route that it will inject in the MSFC
# routing tables.
serverfarm WEBFARM
advertise active
# This is the command that tells the CSM to inject the route for this virtual server. The
# option "active" tells the CSM to remove the route if the backend serverfarm fails.
