1. Introduction These Application notes provide instructions on how to configure Local Survivable Processor (LSP) with the Juniper VF 3000 SBC in an Avaya Hosted IP Telephony (HIPT) R3.0 Solution Environment. The solution described in this document requires the addition of an extra network element, a Network Address Translation (NAT) device at the edge of the service provider’s data center if customers with LSPs are to be supported. This document covers the configuration of the NAT de

data center edge and at the edge of each enterprise site. Note that the Juniper VF 3000 SBC can provide this NAT function. Figure 1 - Private-Public-Private Architecture Another method for WAN connectivity between the enterprise sites and the data center is via a VPN configuration. Figure 2 illustrates this case. The Juniper VF 3000 SBC here must support private-private NAT functionality, where the data center equipment is in a private IP address space and the customer also us

different enterprise customer. The Juniper VF 3000 SBC in the data center can make use of this 1 VLAN information to resolve overlapping IP address issues . The Juniper VF 3000 SBC segregates the access traffic into separate customer streams and routes the traffic to the respective Avaya Communication Managers based on the destination IP address. Figure 2 shows only one enterprise network containing only a single site, but multiple sites (and multiple enterprises using multiple Avaya Com

architecture that may occur. This is similar to Figure 1, except that the data center uses public IP addressing. There is no need for a NAT function between the WAN and the data center in this case. 2.2. Including LSPs in the Solution The Juniper VF 3000 SBC proxies the VoIP traffic for the components located at the enterprise sites and presents all the VoIP traffic to the Avaya Communication Manager with the same IP address – that of the Juniper VF 3000 SBC inside interface.

Figure 3 - Supporting LSPs in the Private-Public-Private Architecture Figure 4 shows the architecture for a corresponding solution applied to the architecture of Figure 2. As in Figure 3, an extra NAT/FW device has been placed at the data center edge. This FW device must be VLAN supported in order to support overlapping address spaces for different LSPs in different enterprises. However, unlike Figure 3, no changes are needed to the equipment at the edge of the enterprise site since t

Configuration Overview This section gives a high-level overview of how to configure enterprise sites and data center networks and how to administer the Avaya Communication Manager servers and LSPs for LSP functionality to work in HIPT R3.0/3.1 and HCC R3.0 solutions. The basic configuration of the solution without LSPs is assumed to already be in place. The remainder of this document will provide the details for wha

3.1. Private-Public-Private Architecture In order to build components in Figure 3 use the following: Enterprise site network configuration: • On the FW/NAT device, configure a static 1-to-1 NAT mapping for each LSP. Data center network configuration: • Add a FW/NAT device, if one is not yet present. On the NAT device, configure static 1- 2 to-1 NAT mapping for each C-LAN/PE IP address. • On the Juniper VF 3000 SBC, for each VF 3000 Session Routing Policy (SRP) used by a set of IP ph

5.1. Service Provider Data Center The Data Center simulates two customers, PC-LAN (Private-Private) and C-LAN (Private- Public-Private). These customers each have their own image of Avaya Communication Manager. These Avaya Communication Manager images both run on the same blade (HT1) in the Avaya SBS3000 environment. The Data Center is privately addressed. The PC-LAN based Avaya Communication Manager image has VPN based enterprise sites (A1 and A2). The C-LAN based Avaya Communica

All enterprise Local Survivable Processors (LSPs) will achieve registration and File Sync via the data center NetScreen-25 Firewall device to the appropriate Avaya Communication Manager image in the Data Center. All enterprise site IP telephones register to the Juniper VF 3000 SBC in the Data Center (which forwards the registration requests on to the appropriate Avaya Communication Manager image). 5.3.1.

6.1.2. Configure Avaya Local Survivable Processors (LSP) Local Survivable Processors (LSP) are normally configured to register directly to Avaya Communication Manager. In the Avaya Hosted IP Telephony environment, the LSPs must be provisioned to register to Avaya Communication Manager via the static 1-to-1 NAT IP address of the NetScreen-25 Firewall (Figure 18) serving the VPN enterprise site. This provisioning is performed via the LSP web GUI interface. In the following example, the LSP
