redistribute isis

This command specifies that IS-IS routes are exported into BGP.

Syntax

redistribute isis [aspath-limit limit] [origin code] [med value] [local-pref value] [route-map name] [match {level-1-internal | level-1-external | level-2-internal | level-2-external | level-1-2}
no redistribute isis [aspath-limit limit] [origin code] [med value] [local-pref value] [route-map name] [match {level-1-internal | level-1-external | level-2-internal | level-2-external | level-1-2}

Parameters

aspath-limit limit (Optional) Specifies the upper limit on AS-path length. Valid values are 0 - 255. Default value is 1.
origin code (Optional) Specifies the origin process attribute. Valid values are:

0 - IGP
1 - EGP
2 - Incomplete

Default value is 2.

med value (Optional) Specifies the multi-exit discriminator value for this route. Valid values are 0 - 4294967295. Default value is 0.
local-pref value (Optional) Specifies a route selection value for this route when the same prefix is learned from multiple peers.
route-map name (Optional) A route-map name to apply to these routes.
match (Optional) Redistribute the specified IS-IS route type only.
level-1-internal Match ISIS level-1 internal routes.
level-1-external Redistribute ISIS level-1 external routes.
level-2-internal Redistribute ISIS level-2 internal routes.
level-2-external Redistribute ISIS level-2 external routes.
level-1-2 Redistribute ISIS level-1 and level-2 routes.

Defaults

  • If a route-map is not specified, no route-map is applied.
  • If an aspath-limit is not specified, the aspath-limit is not included in updates.
  • If an origin code is not specified, the origin is set to the default value of 2 (incomplete).
  • If a med is not specified, the MED attribute is not included in updates. When MED is not included in an update, MED is treated as though it were set to 0.
  • If local-pref is not specified, the local-pref is set to the default value of 100.
  • If an IS-IS route match type is not specified, all IS-IS route types are redistributed.

Mode

BGP Router Configuration or BGP address family configuration mode.

Usage

The redistribute isis command provides for the exporting of IS-IS routes into BGP.

The no redistribute isis command removes redistribution of IS-IS route configuration from the router.

Examples

In the following example BGP is configured to redistribute all IS-IS routes with the local preference set for 100.

System(su-config)->router bgp 65151
System(su-config-bgp)->redistribute isis local-pref 100
