Related Commands • show track ipv6 route - displays information about tracked IPv6 routes, including configuration, current state, and clients which track the route. • track interface ip routing - configures object tracking on the routing status of an IPv4 Layer 3 interface. track ipv6 route metric threshold Configure object tracking on the threshold of an IPv4 route metric. C9000 Series Syntax track object-id ipv6 route ipv6-address/prefix-len metric threshold To return to the default setting, use the no track object-id command. Parameters object-id ipv6-address/ prefix-len Enter the ID number of the tracked object. The range is from 1 to 500. Enter an IPv6 address in X:X:X:X::X format. The valid IPv6 prefix lengths are from /0 to / 128. Defaults none Command Modes CONFIGURATION Command History This guide is platform-specific.

The following is a list of the Dell Networking OS version history for this command. Version 9.9(0.0) 9.8(0.0) 9.7(0.0) 8.3.12.0 8.4.1.0 Description Introduced on the C9010. Introduced on the S3048-ON and S4048-ON. Introduced on the S6000-ON. Introduced on the S4810. Introduced. Usage Information Use this command to create an object that tracks the UP and/or DOWN threshold of an IPv6 route metric. In order for a route's metric to be tracked, the route must appear as an entry in the routing table. A tracked IPv6 route is considered to match an entry in the routing table only if the exact IPv6 address and prefix length match a table entry. For example, when configured as a tracked route, 3333:100:200:300:400::/80 does not match routing table entry 3333:100:200:300::/64. If no route-table entry has the exact IPv6 address and prefix length, the status of the tracked route is considered to be DOWN. When you configure the threshold of an IPv6 route metric as a tracked object, the UP/DOWN state of the tracked route is also determined by the current metric for the route in the routing table. To provide a common tracking interface for different clients, route metrics are scaled in the range 0 to 255, where 0 is connected and 255 is inaccessible. The scaled metric value communicated to a client Object Tracking 1231
