Version Description
7.5.1.0 Added support for IPv6 ISIS.
6.3.1.0 Introduced.
Usage Information
To redistribute a default route (0.0.0.0/0), configure the default-information originate command.
Changing or disabling a keyword in this command does not affect the state of the other command keywords.
When an LSP with an internal metric is received, the Dell EMC Networking OS 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 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 — generate a default route for the IS-IS domain.
• distribute-list out — suppress networks from being advertised in updates. This command filters redistributed
routing information.
redistribute bgp
Redistribute routing information from a BGP process.
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 from 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
setting 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 from 0 to 16777215. The default is
0.
metric-type
{external|
internal}
(OPTIONAL) The external link type associated with the default route advertised into a
routing domain. The two options are:
• external
• internal
route-map map-
name
map-name is an identifier for a configured route map. The route map filters imported
routes from the source routing protocol to the current routing protocol.
If you do not specify a map-name, all routes are redistributed. If you specify a keyword,
but fail to list route map tags, no routes are imported.
Defaults IS-IS Level 2 routes only
Command Modes
• ROUTER ISIS (for IPv4)
• CONFIGURATION-ROUTER-ISIS-ADDRESS-FAMILY-IPV6 (for IPv6)
