View source for Juniper EVPN-VXLAN Centrally Routed Bridging configuration

==Goal==

In this tutorial we will setup a spine/leaf topology with 2 spines and 2 leaves. The goal is to configure EVPN-VXLAN centrally Routed Bridging (CRB)

==What is Centrally Routed Bridging?==

Centrally Routed Bridging( CRB) is just another mechanism that provides routing functionally within the EVPN-VXLAN fabric.

In the CRB design, the inter-VXLAN routing is performed by the spine devices.

==Prerequisites==

For this tutorial I am using :

- EVE-NG 2.0.3-112

- VQFX model: vqfx-10000 running JUNOS 19.4R1.10

- Four(4) servers

====Connectivity with Route Leaking ====

From server srv11 on leaf1 in vlan private1-a-dal we are going to ping server srv44 on leaf2 in vlan private1-b-dal

[[file:ping1.png]]

==== Remove Route Leaking ====

In case that you don't want for servers in VLAN  private1-a-dal to communicate with servers in VALN private1-b-dal and the other way around, you will have to remove some settings under policy and routing instance on both spine switches.

===== Settings to remove on spine1 =====
 set policy-options policy-statement EVPN-IMPORT term VNI102005 from community com2006
 set policy-options policy-statement EVPN-IMPORT term VNI102005 then accept
 set policy-options policy-statement EVPN-IMPORT2006 term 1 from community com2005
 set policy-options policy-statement EVPN-IMPORT2006 term 1 then accept
 set policy-options community com2005 members target:64601:2
 set policy-options community com2006 members target:64601:3

 set routing-instances vlan2005 routing-options auto-export
 set routing-instances vlan2005 vrf-import EVPN-IMPORT
 set routing-instances vlan2006 routing-options auto-export
 set routing-instances vlan2006 vrf-import EVPN-IMPORT2006

===== Settings to remove on spine2 =====

 set policy-options policy-statement EVPN-IMPORT term VNI102005 from community com2006
 set policy-options policy-statement EVPN-IMPORT term VNI102005 then accept
 set policy-options policy-statement EVPN-IMPORT2006 term 1 from community com2005
 set policy-options policy-statement EVPN-IMPORT2006 term 1 then accept
 set policy-options community com2005 members target:64601:2
 set policy-options community com2006 members target:64601:3

 set routing-instances vlan2005 routing-options auto-export
 set routing-instances vlan2005 vrf-import EVPN-IMPORT
 set routing-instances vlan2006 routing-options auto-export
 set routing-instances vlan2006 vrf-import EVPN-IMPORT2006
