# Route Server
This page explains how to set up GoBGP as a [route server](https://tools.ietf.org/html/rfc7947)
## Prerequisites
Assumed that you finished [Getting Started](getting-started.md).
## Configuration
This example uses the following simple configuration file, `gobgpd.conf`. There are three changes from
the configuration file used in [Getting Started](getting-started.md)
- Peers are configured as route server clients (of course!).
- GoBGP doesn't try to connect to peers. It only listens and accepts.
- MD5 passwords are enabled.
```toml
[global.config]
as = 64512
router-id = "192.168.255.1"
[[neighbors]]
[neighbors.config]
neighbor-address = "10.0.255.1"
peer-as = 65001
auth-password = "hoge1"
[neighbors.transport.config]
passive-mode = true
[neighbors.route-server.config]
route-server-client = true
[[neighbors]]
[neighbors.config]
neighbor-address = "10.0.255.2"
peer-as = 65002
auth-password = "hoge2"
[neighbors.transport.config]
passive-mode = true
[neighbors.route-server.config]
route-server-client = true
```
## Starting GoBGP
Let's start gobgpd:
```bash
$ sudo -E gobgpd -f gobgpd.conf
{"level":"info","msg":"Peer 10.0.255.1 is added","time":"2015-04-06T22:55:57+09:00"}
{"level":"info","msg":"Peer 10.0.255.2 is added","time":"2015-04-06T22:55:57+09:00"}
```
GoBGP implements multiple RIBs, that is, each peer has own local
RIB. Let's check respectively.
```bash
$ gobgp neighbor 10.0.255.1 local
Network Next Hop AS_PATH Age Attrs
*> 10.3.0.0/24 10.0.255.2 [65002] 00:05:50 [{Origin: 0} {Med: 0}]
*> 192.168.2.0/24 10.0.255.2 [65002] 00:05:50 [{Origin: 0} {Med: 0}]
```
```bash
$ gobgp neighbor 10.0.255.2 local
Network Next Hop AS_PATH Age Attrs
*> 10.3.0.0/16 10.0.255.1 [65001] 00:06:12 [{Origin: 0} {Med: 0}]
*> 10.3.0.1/32 10.0.255.1 [65001] 00:06:12 [{Origin: 0} {Med: 0}]
```
Of course, you can also look at the adjacent rib-in and rib-out of each peer as done in [Getting Started](getting-started.md).
