Enable Load Balancing Across Different BGP4 Paths

You can use the BGP4 multipath feature to enable load balancing different BGP4+ paths.

About this task

You can use the num variable to specify a maximum number of shared paths. Or you can use the use-load-sharing keyword to use the value that has already configured by means of the ip load-sharing command.

Procedure

Access global configuration mode.
```
device# configure terminal
```
Access BGP configuration mode.
```
device(config)# router bgp
```

Access IPv4 address family configuration mode.

device(config-bgp-router)# address-family ipv4 unicast

Perform one of the following steps to specify load-sharing paths:
- Use the num variable to specify a maximum number of shared paths.
```
device(config-bgp-ipv4u)# maximum-paths 8
```
- Use the value that has been configured by means of the ip load-sharing command.
```
device(config-bgp-ipv4u)# maximum-paths use-load-sharing
```

Example

The following example summarizes the commands in this procedure

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# address-family ipv4 unicast
device(config-bgp-ipv4u)# maximum-paths 8
device(config-bgp-ipv4u)# maximum-paths use-load-sharing
