The Cisco Unified Border Element CUBE provides high availability HA via box to box redundancy configurations when implemented on a Cisco Integrated Services Router Generation 2 router ISR G2 platform. CUBE box to box redundancy leverages the long available router based Hot Standby Routing Protocol HSRP router technology. HSRP technology provides high network availability by routing IP traffic from hosts on networks without relying on the availability of any single router. HSRP is used in a group of routers for selecting an Active router and a Standby router. HSRP monitors both the inside and outside interfaces if any interface goes down, the whole device is considered down, the Standby device becomes active and takes over the responsibilities of the Active router. Box to box redundancy uses the HSRP protocol to form an HSRP ActiveStandby pair of routers. The ActiveStandby pair share the same virtual IP address and continually exchange status messages. CUBE session information is checkpointed across the ActiveStandby pair of routers. This enables the Standby router to immediately take over all CUBE call processing responsibilities if the Active router should go out of service for planned or unplanned reasons. The CUBE box to box redundancy HA implementation supports media preservation over an HSRP switchover of SIP SIP calls, but no call signaling is preserved. This capability is supported as of Cisco IOS Software release 1. T. The call signaling preservation is supported in the latest Cisco IOS Software release 1. T. Note For more information, refer to Cisco Unified Border Element Protocol Independent Features and Setup Configuration Guide, Cisco IOS Release 1. M T. Prerequisites. Requirements. Ensure that you meet these requirements before you attempt this configuration Basic knowledge of how to configure and use Cisco IOS Voice. Basic knowledge of how to configure and use CUBE. Basic knowledge of how HSRP high availability works on general router platforms. The basic requirements for setting up CUBE ISR G2 box to box redundancy include Two identical ISR G2s equipped with the UC Technology Package license SL 2. UC K9 or SL 3. 9 UC K9 installed, 1. G DRAM memory, and Cisco IOS Software release 1. T or later. Both routers must be physically located on the same Ethernet LAN. The CUBE configuration of both routers is identical and must be manually copied from one router to the other. One router is designated the HSRP Active router, the second is the Standby. There are slight differences in the HSRP configuration between the Active and Standby routers. SIP SIP call flows. Components Used. The information in this document is based on a minimum software release of CUBE 8. Cisco IOS release 1. T, implemented on a Cisco 2. Integrated Service Router Generation 2 ISR G2. The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared default configuration. If your network is live, make sure that you understand the potential impact of any command. Conventions. Refer to the Cisco Technical Tips Conventions for more information on document conventions. Background Information. Box to box redundancy requires two identical ISR G2 platforms one configured as the Active, the other as the Standby. HSRP is configured on the physical interfaces to form an HSRP group. If there is a heartbeat failure when the Active router goes down, the second Standby router takes over the IP routing addresses of the first router and continues to forward the same RTP packets that were previously routed to the first router. The RTP streams of established calls are checkpointed between the Active and Standby routers via the HSRP protocol. Therefore the media streams of established calls are preserved over the HSRP failover from the Active to the Standby routers. Calls in a transient state calls that are not established yet, or are in the process of being modified with a transfer or hold function at the time of failover are disconnected. Also, any calls using DSP services such as transcoding are not preserved. Configure. In this section, you are presented with the information to configure the features described in this document. The CUBE HSRP configuration follows a specific order of steps, which includes Enable CUBE and CUBE Redundancy. Enable HSRPConfigure HSRP Communication Transport. Configure HSRP on the Interfaces. Configure the HSRP Timers. What version of SQL Server do I have This unofficial build chart lists all of the known Service Packs SP, Cumulative Updates CU, patches, hotfixes and other. RNodes. For many of the features IRIS provides, a model of the road network topology is required. This model consists of a set of roadway nodes, or rnodes, which. Configure the Media Inactivity Timer. Configure SIP Binding to HSRP Address. Reload the Routers. Point Attached Softswitches to the CUBE HSRP Virtual Address. Reload both the routers after steps 1 5 are completed. A reload is required only when HSRP is configured for the first time on a router. Network Diagram.

These are the explanations of the fields used in this configuration ipc zone default Configures the Inter Device Communication Protocol IPC and enters IPC zone configuration mode. Use this command to initiate the communication link between the Active and Standby devices. Configures an association between the two devices and enters the IPC association configuration mode. Under this, configure the details of the association such as transport protocol, local port, local IP address, remote port and remote IP address. Valid association IDs range from 1 to 2. There are no default association IDs. Restarts a disabled association and its associated transport protocol. For any changes to the transport protocol parameters, this association must be shut down. Configures Stream Control Transmission Protocol SCTP as the transport protocol for this association and enables SCTP protocol configuration mode.
