Deployment Guide

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
DellEMC(conf)# ipv6 route 44::/64 33::1 weight 100
DellEMC(conf)# ipv6 route 44::/64 33::2 weight 200
DellEMC(conf)# do show running-config | grep ipv6 route
DellEMC(conf)# ipv6 route vrf vrf_test 44::/64 33::1 weight 100
DellEMC(conf)# ipv6 route vrf vrf_test 44::/64 33::2 weight 200
DellEMC(conf)# do show running-config | grep ipv6 route vrf

Usage
Information
Because this command is enabled by default, it does not appear in the running configuration. When
you disable unicast routing, the no ipv6 unicast-routing command is included in the running
configuration. Whenever unicast routing is disabled or re-enabled, DellEMC Networking OS generates a
syslog message indicating the action.
Disabling unicast routing on an E-Series chassis causes the following behavior:
