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-
to-1 NAT mapping for each C-LAN/PE
2
IP address.
• On the Juniper VF 3000 SBC, for each VF 3000 Session Routing Policy (SRP) used by a
set of IP phones, configure the native IP address of each LSP.
Avaya Communication Manager server administration:
• SA8853 Support of LSPs Behind Nat Green feature must be installed.
• Add two IP node names for each LSP, one for the statically mapped NAT WAN IP
address of each enterprise LSP and the other for its native private IP address.
• Administer the “lsp” form with the statically mapped NAT WAN IP address of each LSP.
• Administer the LSP list on the “ip-network-region” form, page 2 with the native (private)
IP address of each LSP.
LSP configuration:
• Enter the corresponding NAT WAN IP addresses of Avaya Communication Manager
servers/C-LANs/PEs in the “primary controller” and “C-LAN IP address of the primary
controller” fields on the LSP configuration web page.
3.2. Private-Private Architecture
In order to build components in Figure 4 use the following:
Enterprise site network configuration:
• None.
Data center network configuration:
• Add a VLAN supported FW/NAT device, if one is not yet present. On the FW/NAT
device, set up static NAT mappings so that enterprise site address space is converted to
data center address space, and vice versa, for IP addresses of LSPs in enterprise sites
address spaces and CM servers/C-LANs/PEs in the data center address space.
• On the Juniper VF 3000 SBC, for each VF session routing policy (SRP) used by a set of
IP phones, configure the native IP address of each LSP.
2 PE is an acronym for Processor Ethernet, an interface to CM that was formerly known as PC-LAN.
