Configure Redistribution to BGP

Configure redistribute entries for BGP to announce routes of a certain source type to BGP, for example, DvR, direct, static, Routing Information Protocol (RIP), and Open Shortest Path First (OSPF). If you do not configure a route policy, then the switch uses the default action based on metric, metric type, and subnet. Use a route policy to perform detailed redistribution.

Before you begin

  • If required, configure a route policy.

  • When you configure BGP on a specific VRF instance, the VRF must have an RP trigger of BGP.

  • To perform this procedure on a non-default VRF, you must first change the VRF instance. For information about how to use EDM for a non-default VRF, see Select and Launch a VRF Context View. All parameters might not be available in non-default VRFs.

  • Before you redistribute DvR host routes to BGP, ensure that you disable BGP aggregation and BGP auto-summarization of networks. Disabling these options ensures that all DvR host routes are advertised into BGP correctly, and are not summarized.

Procedure

  1. In the navigation pane, expand Configuration > IP.
  2. Select BGP.
  3. Select the Redistribute tab.
  4. Select Insert.
  5. Configure the source protocol.
  6. Optional: If required, choose a route policy.
  7. Configure the metric to apply to redistributed routes.
  8. Enable the redistribution instance.
  9. Select Insert.

Redistribute field descriptions

Use the data in the following table to use the Redistribute tab.

Name

Description

DstVrfId

Specifies the destination VRF instance (read-only).

Protocol

Specifies the protocols that receive the redistributed routes.

SrcVrfId

Specifies the source VRF instance (read-only).

RouteSource

Specifies the source protocol for the route redistribution entry.

Enable

Enables (or disables) a BGP redistribute entry for a specified source type.

RoutePolicy

Configures the route policy to use for the detailed redistribution of external routes from a specified source into the BGP domain.

Metric

Configures the metric for the redistributed route. The value can be a range between 0–65535. The default value is 0. Use a value that is consistent with the destination protocol.
