Today i will discuss about MPLS VPN Connectivity diagram or how a MPLS VPN domain buildup in service provider environment. [boxads]
MPLS VPN domain are consist mainly P & PE router. P router means provider router, and PE router means provider edge router. P router are only forwarded Level & PE router collect & distribute customer prefixes. If we look bellow diagram we see P & PE router how connected.
MPLS VPN Connectivity diagram:
Task of P router:
- P routers are in the core of the MPLS cloud
- P routers do not need to run BGP and doesn’t need to have any VPN knowledge
- Forward packets by looking at labels
- P and PE routers share a common IGP

Task of PE router:
- Edge Routers
- Use MPLS with P routers
- Uses IP with CE routers
- Connects to both CE and P routers.
- Distribute VPN information through MP-BGP to other PE router with VPN-IPv4 addresses, Extended Community, Label.
