Users Guide

NOTE: If you disable the interface with an IPv6 address associated with the
keyword permanent, the route disappears from the routing table.
weight weight-
value
Enter the keyword weight followed by a weight value. The range is from 0 to 255.
NOTE: Weight for a static route can be added only for the destination
address and not for the route pointing to destination a interface.

Usage Information
When the interface goes down, Dell Networking OS withdraws the route. The route is re-installed, by Dell
Networking OS, when the interface comes back up. When a recursive resolution is “broken,” Dell Networking
OS withdraws the route. The route is re-installed, by Dell Networking OS, when the recursive resolution is
satised.
After an IPv6 static route interface is created, if an IP address is not assigned to a peer interface, the peer
must be manually pinged to resolve the neighbor information.
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.
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
