Multihoming is the practice of connecting a host or a computer network to more than one network. This can be done in order to increase reliability or performance. A typical host or end-user network is connected to just one network. Connecting to multiple networks can increase reliability because if one connection fails, packets can still be routed through the remaining connection. Connecting ...
In Multiprotocol Label Switching (MPLS), a P router or provider router is a label switch router (LSR) that functions as a transit router of the core network. [1] The P router is typically connected to one or more PE routers. Here's one scenario: A customer who has facilities in LA and Atlanta wants to connect these sites over an MPLS VPN ...
With source-specific routing, each host interface has multiple addresses, one per provider-dependent prefix. For outgoing traffic, host software must choose the right source address. Various techniques for doing that have been suggested, at the network layer, [ 4 ] above the network layer (see Shim6 ), or by using multipath techniques at the ...

Provider Router (P): A Provider router is also called a transit-router, it sits in an MPLS network and is responsible for establishing label-switched paths between the PE routers. [27] Provider edge router (PE): An MPLS-specific router in the network's access layer that interconnects with customer edge routers to provide layer 2 or layer 3 VPN ...
In a typical deployment, customer edge (CE) routers handle local routing in a traditional fashion and disseminate routing information into the provider edge (PE) where the routing tables are virtualized. The PE router then encapsulates the traffic, marks it to identify the VRF instance, and transmits it across the provider backbone network to ...

In the specific context of an MPLS-based virtual private network (VPN), LERs that function as ingress or egress routers to the VPN are often called provider edge (PE) routers. Devices that function only as transit routers are similarly called provider (P) routers. [14] The job of a P router is significantly easier than that of a PE router.
