Reference Guide

When an LSP with an internal metric is received, the FTOS considers the route cost while
considering the advertised cost to reach the destination.
Redistributed routing information is filtered with the distribute-list out command to
ensure that the routes are properly are passed to the receiving routing protocol.
How a metric value assigned to a redistributed route is advertised depends on how on the
configuration of the metric-style command. If the metric-style command is set for
Narrow or Transition mode and the metric value in the
redistribute command is set to a
number higher than 63, the metric value advertised in LSPs is 63. If the metric-style
command is set for Wide mode, the metric value in the redistribute command is
advertised.

Commands
• default-information originate – generates a default route for the IS-IS domain.
• distribute-list out – suppresses networks from being advertised in updates. This
command filters redistributed routing information.
redistribute bgp
Redistribute routing information from a BGP process. (New command in Release 6.3.1.)
E-Series, S4810
Syntax
redistribute bgp AS number [level-1| level-1-2 | level-2]
[metric metric-value] [metric-type {external| internal}]
[route-map map-name]
To return to the default values, use the no redistribute bgp command with the
appropriate parameters.
Parameters
AS number Enter a number that corresponds to the autonomous system number.
The range is 1 to 65355.
level-1 (OPTIONAL) Routes are independently redistributed into IS-IS Level 1
routes only.
level-1-2 (OPTIONAL) Routes are independently redistributed into IS-IS Level 1
and Level 2 routes.
level-2 (OPTIONAL) Routes are independently redistributed into IS-IS as
Level 2 routes only. This is the default.
metric metric-
value
(OPTIONAL) The value used for the redistributed route. Use a metric
value that is consistent with the destination protocol. The range is 0
to 16777215. The default is 0.
