High- Availability Solution with a Single
Nokia IP40 Security Platform
In this scenario, the branch office is always securely connected to the central office on the
Internet with single Nokia IP40 Security Platform by using DSL or cable connection or dial-up
as backup. Nokia IP40 (R1) connects to the RO1 and establishes VPN connection on DSL
(preferred connection). Nokia IP40 (R1) and BGP peer (R3) located in RO1 establishes a BGP
connection over VPN. If this BGP session fails because of any service interruption, dial-up is
activated. Nokia IP40 (R1) connects to RO2 and establishes a VPN connection. R1, and the BGP
peer (R4) located in RO2 establish a BGP connection over VPN, and the traffic from the branch
office flows through this alternative path. As soon as IP40 (R1) detects the established BGP
session on the DSL connection, the dial-up connection to RO2 is discontinued.
