Version Description
9.9(0.0) Introduced on the FN IOM.
9.4(0.0) Supported on the FN I/O Aggregator.
Usage
Information
Using the following example of a static route: ip route 33.33.33.0 /24 tengigabitethernet 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, Dell Networking OS installs
the static route.
● When the interface goes down, Dell Networking OS withdraws the route.
● When the interface comes up, Dell Networking OS re-installs the route.
● When recursive resolution is “broken,” Dell Networking OS withdraws the route.
● When recursive resolution is satisfied, Dell Networking OS re-installs the route.
