# Peer Group
This page explains how to configure the Peer Group features.
With Peer Group, you can set the same configuration to multiple peers.
## Contents
- [Prerequisite](#prerequisite)
- [Configuration](#configuration)
- [Verification](#verification)
## Prerequisite
Assumed that you finished [Getting Started](getting-started.md).
## Configuration
Below is the configuration to create a peer group.
```toml
[[peer-groups]]
[peer-groups.config]
peer-group-name = "sample-group"
peer-as = 65001
[[peer-groups.afi-safis]]
[peer-groups.afi-safis.config]
afi-safi-name = "ipv4-unicast"
[[peer-groups.afi-safis]]
[peer-groups.afi-safis.config]
afi-safi-name = "ipv4-flowspec"
```
The configurations in this peer group will be inherited to the neighbors which is the member of this peer group.
In addition, you can add additional configurations to each member.
Below is the configuration to create a neighbor which belongs this peer group.
```toml
[[neighbors]]
[neighbors.config]
neighbor-address = "172.40.1.3"
peer-group = "sample-group"
[neighbors.timers.config]
hold-time = 99
```
This neighbor belongs to the peer group, so the peer-as is 65001, and ipv4-unicast and ipv4-flowspec are enabled.
Furthermore, an additional configuration is set, the hold timer is 99 secs.
## Verification
You can see the neighbor configuration inherits the peer group config by running `gobgp neighbor` command.
```shell
$ gobgp neighbor 172.40.1.3
BGP neighbor is 172.40.1.3, remote AS 65001
BGP version 4, remote router ID 172.40.1.3
BGP state = established, up for 00:00:05
BGP OutQ = 0, Flops = 0
Hold time is 99, keepalive interval is 33 seconds
Configured hold time is 99, keepalive interval is 33 seconds
