When the Peeredge Switches are SBC is directly connected to a service provider or customer’s MPLS network, we assign each customer is assigned a dedicated MPLS Virtual Routing and Forwarding (VRF) instance.
If there is an a network-to-network interface (NNI) connection directly into the 46Labs datacenters46 Labs data centers, then a dedicated VLAN in the Peeredge datacenters are data center is connected to each customer’s VRF. The 46Labs datacenter The 46 Labs data center subnets (hosting the Peeredge SwitchesSBCs) are advertised into the customer’s VRF via multi-protocol BGP. The customer’s MPLS VRF must contain the IP routes necessary to reach the SIP Trunking endpoints. If If a media flow-around design is used, then the IP routes for all IP endpoints (i.e. Phonesphones) must also be advertised and reachable in the customer’s MPLS VRF. Since Since each MPLS customer has a dedicated VRF, MPLS networks are typically considered to be a secure network. As such, use the TCP or UDP protocols can be used to communicate with the Peeredge SwitchesSBC.
If there in is no NNI connection directly into the 46Labs datacenters46 Labs data centers, then the Peeredge Switch SBC can be place placed in the Service Provider or Customer network to access the MPLS network.
If there in no NNI connection directly into the 46Labs datacenters, then 46 Labs data centers, an additional network topology will be is required to reach the 46Labs Cloud46 Labs cloud.
