Example: Advertising Multiple Paths in BGP

Requirements

This example uses the following hardware and software components:

• Eight BGP-enabled devices.
• Five of the BGP-enabled devices do not necessarily need to be routers. For example, they can be EX Series Ethernet Switches.
• Three of the BGP-enabled devices are configured to send multiple paths or receive multiple paths (or both send and receive multiple paths). These three BGP-enabled devices must be M Series Multiservice Edge Routers, MX Series 3D Universal Edge Routers, or T Series Core Routers.
• The three routers must be running Junos OS Release 11.4 or later.

Overview

In this example, Router R5, Router R6, and Router R7 redistribute static routes into BGP. Router R1 and Router R4 are route reflectors. Router R2 and Router R3 are clients to Route Reflector R1. Router R8 is a client to Route Reflector R4.

Route reflection is optional when multiple-path advertisement is enabled in BGP.

With the add-path send path-count 6 configuration, Router R1 is configured to send up to six paths (per destination) to Router R4.

With the add-path receive configuration, Router R4 is configured to receive multiple paths from Router R1.

With the add-path send path-count 6 configuration, Router R4 is configured to send up to six paths to Router R8.

With the add-path receive configuration, Router R8 is configured to receive multiple paths from Router R4.

The add-path send prefix-policy allow_199 policy configuration (along with the corresponding route filter) limits Router R4 to sending multiple paths for only the 199.1.1.1/32 route.

CLI Quick Configuration

To quickly configure this example, copy the following commands, paste them into a text file, remove any line breaks, change any details necessary to match your network configuration, and then copy and paste the commands into the CLI at the [edit] hierarchy level.

Meaning

The show route receive-protocol command shows that Router R4 receives two paths to the 198.1.1.1/32 destination and three paths to the 199.1.1.1/32 destination. The show route advertising-protocol command shows that Router R4 advertises only one path to the 198.1.1.1/32 destination and advertises all three paths to the 199.1.1.1/32 destination.

Because of the prefix policy that is applied to Router R4, Router R4 does not advertise multiple paths to the 198.1.1.1/32 destination. Router R4 advertises only one path to the 198.1.1.1/32 destination even though it receives multiple paths to this destination.

Verifying That Router R8 Is Receiving Multiple Paths

Purpose

Make sure that Router R8 receives multiple paths to the 199.1.1.1/32 destination through Router R4. Make sure that Router R8 receives only one path to the 198.1.1.1/32 destination through Router R4.

Checking the Path ID

Purpose

On the downstream devices, Router R4 and Router R8, verify that a path ID uniquely identifies the path. Look for the Addpath Path ID: string.
