Usage
Information
Using the following example of a static route: ip route 33.33.33.0 /24 gigabitethernet 0/0
172.31.5.43
• The software installs a next hop that is not on the directly connected subnet but which
recursively resolves to a next hop on the interface’s configured subnet. In the example,
if gig 0/0 has an ip address on subnet 2.2.2.0 and if 172.31.5.43 recursively resolves to
2.2.2.0, FTOS installs the static route.
• When the interface goes down, FTOS withdraws the route.
• When the interface comes up, FTOS re-installs the route.
• When recursive resolution is “broken,” FTOS withdraws the route.
• When recursive resolution is satisfied, FTOS re-installs the route.
