Table 25: show route extensive Output Fields (continued)
Field DescriptionField Name
If the route is inactive, the reason for its current state is indicated. Typical reasons include:
• Active preferred—Currently active route was selected over this route.
• Always compare MED—Path with a lower multiple exit discriminator (MED) is available.
• AS path—Shorter AS path is available.
• Cisco Non-deterministic MED selection—Cisco nondeterministic MED is enabled and a path with a
lower MED is available.
• Cluster list length—Path with a shorter cluster list length is available.
• Forwarding use only—Path is only available for forwarding purposes.
• IGP metric—Path through the next hop with a lower IGP metric is available.
• IGP metric type—Path with a lower OSPF link-state advertisement type is available.
• Interior > Exterior > Exterior via Interior—Direct, static, IGP, or EBGP path is available.
• Local preference—Path with a higher local preference value is available.
• Next hop address—Path with a lower metric next hop is available.
• No difference—Path from a neighbor with a lower IP address is available.
• Not Best in its group—Occurs when multiple peers of the same external AS advertise the same
prefix and are grouped together in the selection process. When this reason is displayed, an additional
reason is provided (typically one of the other reasons listed).
• Number of gateways—Path with a higher number of next hops is available.
• Origin—Path with a lower origin code is available.
• OSPF version—Path does not support the indicated OSPF version.
• RIB preference—Route from a higher-numbered routing table is available.
• Route destinguisher—64-bit prefix added to IP subnets to make them unique.
• Route metric or MED comparison—Route with a lower metric or MED is available.
• Route preference—Route with a lower preference value is available.
• Router ID—Path through a neighbor with a lower ID is available.
• Unusable path—Path is not usable because of one of the following conditions: the route is damped,
the route is rejected by an import policy, or the route is unresolved.
• Update source—Last tiebreaker is the lowest IP address value.
Inactive reason
Autonomous system (AS) number of the local routing device.Local AS
How long the route has been known.Age
Accumulated interior gateway protocol (AIGP) BGP attribute.AIGP
Cost value of the indicated route. For routes within an AS, the cost is determined by IGP and the
individual protocol metrics. For external routes, destinations, or routing domains, the cost is determined
by a preference value.
Metric
Metric value for BGP path selection to which the IGP cost to the next-hop destination has been added.MED-plus-IGP
For MPLS LSPs, state of the TTL propagation attribute. Can be enabled or disabled for all
RSVP-signaled and LDP-signaled LSPs or for specific VRF routing instances.
For sample output, see show route table.
