Administrator Guide

A route is considered for weighted ECMP calculations only if each paths corresponding to that route is
configured with a weight.
Example
Dell(conf)#ipv6 route 44::/64 33::1 weight 100
Dell(conf)#ipv6 route 44::/64 33::2 weight 200
Dell(conf)#do show running-config | grep ipv6 route
Dell(conf)#ipv6 route vrf vrf_test 44::/64 33::1 weight 100
Dell(conf)#ipv6 route vrf vrf_test 44::/64 33::2 weight 200
Dell(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, Dell Networking OS generates a syslog
message indicating the action.
Disabling unicast routing on an E-Series chassis causes the following behavior:
● static and protocol learned routes are removed from RTM and from the CAM; packet forwarding to
these routes is terminated
● connected routes and resolved neighbors remain in the CAM and new IPv6 neighbors are still
discoverable
● additional protocol adjacencies (OSPFv3 and BGP4) are brought down and no new adjacencies are
formed
● the IPv6 address family configuration (under router bgp) is deleted
● IPv6 Multicast traffic continues to flow unhindered
