Usage Information Using the following example of a static route: ip route 33.33.33.0 /24 tengigabitethernet 1/1 172.31.5.43
• 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 congured subnet. In the example, if tengig 1/1 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 satised, Dell Networking OS re-installs the route.
You can specify a weight for an IPv4 or IPv6 static route. If the weight value of a path is 0, then that path is
not used for forwarding when weighted ECMP is in eect. Also, if a path corresponding to a static route
(destination) has a non-zero weight assigned to it and other paths do not have any weight congured, then
regular ECMP is used for forwarding.
You can specify the weight value only to destination address and not on the egress port.
A route is considered for weighted ECMP calculations only if each paths corresponding to that route is
congured with a weight.
You cannot use the VRF attribute of this command to congure routes in a management VRF. When a
specic VRF is deleted, all the congured static routes corresponding to that VRF are automatically
removed.
