+# Route Reflector
+
+This page explains how to set up GoBGP as a route reflector.
+
+## Prerequisites
+
+Assumed you finished [Getting Started](https://github.com/osrg/gobgp/blob/master/docs/sources/getting-started.md).
+
+## Configuration
+
+Configure `RouteReflector.RouteReflectorConfig` section to enable route reflector functionality.
+The configuration below configures two route reflector clients and two normal iBGP peers.
+
+```toml
+[Global]
+ [Global.GlobalConfig]
+ RouterId = "192.168.0.1"
+ As = 65000
+[Neighbors]
+ [[Neighbors.NeighborList]]
+ [Neighbors.NeighborList.NeighborConfig]
+ NeighborAddress = "192.168.10.2"
+ PeerAs = 65000
+ [Neighbors.NeighborList.RouteReflector.RouteReflectorConfig]
+ RouteReflectorClient = true
+ RouteReflectorClusterId = "192.168.0.1"
+ [[Neighbors.NeighborList]]
+ [Neighbors.NeighborList.NeighborConfig]
+ NeighborAddress = "192.168.10.3"
+ PeerAs = 65000
+ [Neighbors.NeighborList.RouteReflector.RouteReflectorConfig]
+ RouteReflectorClient = true
+ RouteReflectorClusterId = "192.168.0.1"
+ [[Neighbors.NeighborList]]
+ [Neighbors.NeighborList.NeighborConfig]
+ NeighborAddress = "192.168.10.4"
+ PeerAs = 65000
+ [[Neighbors.NeighborList]]
+ [Neighbors.NeighborList.NeighborConfig]
+ NeighborAddress = "192.168.10.5"
+ PeerAs = 65000
+```
+
+## Check route reflector behavior
+
+Let's check adj-rib-out of a route reflector client.
+
+```bash
+$ gobgp neighbor 192.168.10.2 adj-out
+Network Next Hop AS_PATH Attrs
+10.0.2.0/24 192.168.10.3 [{Origin: i} {Med: 0} {LocalPref: 100} {Originator: 192.168.0.3} {ClusterList: [192.168.0.1]}]
+10.0.3.0/24 192.168.10.4 [{Origin: i} {Med: 0} {LocalPref: 100} {Originator: 192.168.0.4} {ClusterList: [192.168.0.1]}]
+10.0.4.0/24 192.168.10.5 [{Origin: i} {Med: 0} {LocalPref: 100} {Originator: 192.168.0.5} {ClusterList: [192.168.0.1]}]
+```
+
+You can see the routes from other iBGP peers are reflected.
+Also Originator and ClusterList path attributes are added.
+
+For the normal iBGP peer's adj-rib-out
+
+```bash
+$ gobgp neighbor 192.168.10.4 adj-out
+Network Next Hop AS_PATH Attrs
+10.0.1.0/24 192.168.10.2 [{Origin: i} {Med: 0} {LocalPref: 100}]
+10.0.2.0/24 192.168.10.3 [{Origin: i} {Med: 0} {LocalPref: 100}]
+```
+
+Only the routes from route reflector clients are advertised via GoBGP.
+Originator and ClusterList path attributes are not added.
