Distribute BGP Flowspec Rules

Before configuring distribution, complete the following tasks:

Configure BGP Flowspec Rules
Enable the BGP Flowspec Address Family and Activate Neighbors

From privileged EXEC mode, enter global configuration mode.
```
device# configure terminal
```
Enable BGP and enter BGP configuration mode.
```
device(config)# router bgp
```
Enter BGP address-family IPv4 flowspec configuration mode.
```
device(config-bgp-router)# address-family ipv4 flowspec
```
Distribute a route map that is already configured with the BGP flowspec rules.
```
device(config-bgp-ipv4fs)# distribute flowspec-map
```
This example shows how to distribute a route map named flowspec-map under the BGP flowspec IPv4 address family.

The following example summarizes the commands in this task.

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# address-family ipv4 flowspec
device(config-bgp-ipv4fs)# distribute flowspec-map
