track ipv6 route reachabilityConfigure object tracking on the reachability of an IPv6 route.Syntax track object-id ipv6 route ip-address/prefix-len reachabilityTo return to the default setting, use the no track object-id command.Parameters object-id Enter the ID number of the tracked object. The range is from 1to 500.ipv6-address/prefix-lenEnter an IPv6 address in X:X:X:X::X format. The valid IPv6 prefixlengths are from /0 to / 128.Defaults noneCommand Modes CONFIGURATIONCommand History This guide is platform-specific. For command information about other platforms, referto the relevant Dell Networking OS Command Line Reference Guide.The following is a list of the Dell Networking OS version history for this command.Version Description9.9(0.0) Introduced on the C9010.9.8(0.0) Introduced on the S3048-ON and S4048-ON.9.7(0.0) Introduced on the S6000-ON.8.3.12.0 Introduced on the S4810.8.4.1.0 Introduced.Usage Information Use this command to create an object that tracks the reachability of an IPv6 route. Inorder for a route’s reachability to be tracked, the route must appear as an entry in therouting table.A tracked route is considered to match an entry in the routing table only if the exactIPv6 address and prefix length match a table entry. For example, when configured as atracked route, 3333:100:200:300:400::/80 does not match routing table entry3333:100:200:300::/64. If no route-table entry has the exact IPv6 address and prefixlength, the tracked route is considered to be DOWN.When you configure IPv6 route reachability as a tracked object, the UP/DOWN state ofthe tracked route is also determined by the entry of the next-hop address in the ARPcache. A tracked route is considered to be reachable if there is an ARP cache entry forthe route's next-hop address.Object Tracking 1478
