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

QinQ and Link Aggregation over EX-4200

Scenario:

• Two EX-4200 switches are connected back to back over ge-0/0/12 & ge-0/0/13 interfaces.
• Both the above mentioned interfaces are part of Aggregated Ethernet interfaces called ae0.
• ae0.0 interfaces are configured in Trunk mode with VLANs 12 (DATA) & 24 (qinq).
• QinQ has been configured over ge-0/0/24 interfaces & these interfaces are in Access mode.
• Two Cisco C851 routers are connected with ge-0/0/24 interfaces of EX-4200s.
• Fa4 interfaces of Cisco 851 are configured with two tagged sub-interfaces.
• Interfaces ge-0/0/10 are configured with VLAN 12 (DATA) in access mode and laptops have been connected to them.

MPLS L3 VPN provisioning over Junos & IOS based PEs

Scenario:

This topology elaborates MPLS L3 VPN provisioning over IOS & Junos based PE routers using different PE-CE protocols. 

·  The ISP’s core is using ISIS as IGP.
·   MPLS (LDP) runs on top of ISIS.
·   The CORE router is functioning as Route Reflector for Junos_PE, Junos_PE2      & IOS_PE.
·    The three PEs have MP-BGP relation with CORE (RR).
·    The client has 3 sites, CE1, CE2 & CE3.
·    PE-CE protocol between IOS_PE & CE1 is non-dynamic i.e., static routing.
·    PE-CE protocol between Junos_PE & CE2 is eBGP.
·    PE-CE protocol between Junos_PE2 & CE3 is OSPF.
