The MPLS VPN Super Backbone also enables customers to use multiple area 0 backbones on their sites. Each site can have a separate area 0 as long as it is connected to the MPLS VPN Super Backbone. The result is the same as a partitioned area 0 …

Figure 3 – MPLS Layer 2 VPN. Traffic that is coming through the interface Gi0/0 on R2 is encapsulated and pushed to R5 with two labels (Figure … When using OSPF as the PE-CE routing protocol in combination with MP-BGP, the ISP MPLS VPN backbone is considered by OSPF as a “super area 0” that is used to link all OSPF area at different sites. This special “virtual area” is called the OSPF super-backbone and is emulated by passing OSPF … Let’s add a backdoor link between CE1 and CE2. This could be a backup link that you want to use in case the MPLS VPN provider has issues: Let’s enable OSPF on this interface and advertise it in area 0: CE1 (config)#router ospf 1 CE1 (config-router)#network 192.168.15.0 0.0.0.255 area … The area 0 of each VPN site must be connected to the MPLS VPN backbone because OSPF requires that the backbone area be contiguous.

This handbook aims to give hands-on practice on several MPLS VPN OSPF. Area 0. IBGP. LSP. AS 100. Configurations. VRF Configuration. 2014. 8. 18. The BGP/MPLS VPN backbone acts as either an OSPF backbone (area 0) or an OSPF area above the backbone. In this topology, OSPF is the routing Area 3 • OSPF area 0 might extend into individual sites • MPLS VPN backbone has to become a super-backbone for a single OSPF domain The MPLS VPN architecture extends the OSPF architecture by introducing another backbone above OSPF area 0 (superbackbone). The OSPF …
Using OSPF in an MPLS VPN Environment
MPLS on OSPF. The Open Shortest Path First (OSPF) routing protocol was designed to support hierarchical networks with a central backbone. The network running OSPF is divided into areas. All areas have to be directly connected to the backbone area (area 0). The whole OSPF network (backbone area and any other areas … 2009. 6. 28. 수 있게 되는 것이며, 이 기술이 바로 MPLS VPN이다.

As er know that in OSPF Area 0 is an backbone area , So even if we plane to run OSPF as a CE-PE routing protocol we can run , But if we assume that in existing network we are already running OSPF & configured with Area 0, So in this case how we can run OSPF …
