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
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
