Usage
Information
When the interface goes down, Dell EMC Networking OS withdraws the route. The route is re-installed,
by Dell EMC Networking OS, when the interface comes back up. When a recursive resolution is “broken,”
Dell EMC Networking OS withdraws the route. The route is re-installed, by Dell EMC Networking OS,
when the recursive resolution is satisfied.
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 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
