● 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.
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 effect. 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
configured, 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
configured with a weight.
You cannot use the VRF attribute of this command to configure routes in a management VRF. When
a specific VRF is deleted, all the configured static routes corresponding to that VRF are automatically
removed.
Example
Dell(conf)# ip route 1.1.1.0/24 4.4.4.2 weight 100
Dell(conf)# ip route 1.1.1.0/24 6.6.6.2 weight 200
Dell(conf)# do show running-config | grep route ip route 1.1.1.0/24
4.4.4.2 weight 100 ip route 1.1.1.0/24 6.6.6.2 weight 200
Dell(conf)# ip route vrf test 1.1.1.0/24 4.4.4.2 weight 100
Dell(conf)# ip route vrf test 1.1.1.0/24 6.6.6.2 weight 200
Dell(conf)#
Dell(conf)# do show running-config | grep route ip route vrf test
