Nokia Network Voyager for IPSO 4.0 Reference Guide 2736. To specify the order in which next hops are selected, enter a value from one to eight in thePreference text box. The lower the value the more preferred the link.The next preferred value is selected as the next hop only when an interface fails. A non-reachable link is not selected as the next hop.The preference option also supports equal-cost multipath routing. For each preference value,you can configure as many as eight gateway addresses. The nexthop gate address for eachpacket to the destination is selected based on the nexthop algorithm that is configured.7. Click Apply.8. Click Save to make your changes permanent.Routing ConfigurationConfiguring OSPFv3IPSO supports OSPFv3, which supports IPv6 addressing and is based on RFC 2740. OSPFv3has essentially the same configuration parameters as OSPFv2, except that you enter them fromthe Network Voyager page that you access by clicking Routing Configuration underConfiguration > System Configuration > IPv6 Configuration in the tree view. For moreinformation, see “OSPF” on page 353.Configuring RIPng1. Click RIPng under Configuration > System Configuration > IPv6 Configuration > RoutingConfiguration in the tree view.2.
