MPLS L3 VPN provisioning over IOS, JUNOS & VRP (Huawei) based PEs

Scenario:

This topology elaborates MPLS L3 VPN provisioning using Cisco's IOS, Juniper's Junos & Huawei's VRP (Versatile Routing Platform Software) based PE routers using different PE-CE routing protocols. 

·   The ISP’s core is using ISIS as IGP.

·   MPLS (LDP) runs on top of ISIS.

·   The RR JUNOS router is functioning as Route Reflector for Junos-PE, IOS-PE & VRP-PE.

·   The three PEs have MP-BGP relation with RR JUNOS.

·   The client has 3 sites running different platforms, i.e., IOS-CE, JUNOS-CE, VRP-CE.

·   PE-CE protocol between JUNOS-PE and IOS-CE is OSPF.

·   PE-CE protocol between IOS-PE and JUNOS-CE is eBGP.

·   PE-CE protocol between VRP-PE & VRP-CE is ISIS.

Platforms used in this topology are:

IOS-PE = Cisco IOS Software, 3600 Software (C3640-JK9O3S-M), Version 12.4(16a) running in GNS3

IOS-CE = Cisco IOS Software, 2600 Software (C2691-ADVENTERPRISEK9-M), Version 12.4(5a) running in GNS3

All JUNOS routers= Model: olive, JUNOS Base OS Software Suite [12.1R1.9] running in GNS3

VRP-PE =  Huawei Versatile Routing Platform Software VRP (R) software, Version 5.120 (AR2200 V200R003C01SPC900) running on Huawei AR2220 Router

VRP-CE = Huawei Versatile Routing Platform Software. Software Version : USG2110 00R001C00SPCa00 (VRP (R) Software, Version 5.30) running on Secospace USG2110-F-W
