Command History
Usage Guidelines The traffic engineering process is used to decide if a configured traffic engineering route should be
in
stalled in the forwarding table.
The first step is to determine if the route is up. If the route is enabled, the LSP tunnel interface is up, the
l
oop prevention check is either disabled or passed, and the traffic engineering route is up.
If multiple routes for the same filter are up, a route is selected based on administrative preference.
If loop prevention is enabled, metrics are solicited from the tunnel tail, and the loop prevention algorithm
i
s run on the result. For a discussion of the loop prevention algorithm, see the show ip
traffic-engineering metrics command.
filter-number The number of the traffic engineering filter to be forwarded through the use
o
f this traffic engineering route, if the route is installed.
interface Label switched path (LSP)-encapsulated tunnel on which the traffic-passing
f
ilter should be sent, if this traffic engineering route is installed.
preference num
ber (Optional) This is a number from 1 to 255, with a lower value being more

off. The default is on.
