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 configured 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 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.
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 1.1.1.0/24 4.4.4.2 weight 100 ip route vrf test
1.1.1.0/24 6.6.6.2 weight 200
