Cisco IP Communication Express Quick Config Tool. What's New in Cisco Product Documentation. ASA/PIX 7.x: Redundant or Backup ISP Links Configuration Example. Introduction A problem with static routes is that no inherent mechanism exists to determine if the route is up or down.
The route remains in the routing table even if the next hop gateway becomes unavailable. Static routes are removed from the routing table only if the associated interface on the security appliance goes down. In order to solve this problem, a static route tracking feature is used to track the availability of a static route and, if that route fails, remove it from the routing table and replace it with a backup route. Configure the ASA for Redundant or Backup ISP Links. Introduction This document describes how to configure the Cisco ASA 5500 Series Adaptive Security Appliance (ASA) for the use of the static route tracking feature in order to enable the device to use redundant or backup Internet connections.
Prerequisites Requirements There are no specific requirements for this document. Components Used The information in this document is based on these software and hardware versions: Cisco VoIP/CCME - CallManager. Services Overview. L2L VPN on Cisco ASA with Overlapping Addresses – Access to Both ASAs (w/ GNS3 Lab) - Intense School.
One of the things you may come across as a network engineer is configuring a VPN tunnel between two sites that have the same IP address space, i.e. overlapping subnets.
There are many reasons this can happen, such as when two companies merge or if you are connecting to a business partner who is already using your IP address space. In the first case of a merger, you will probably have access to (or at least control over) the devices at both ends of the VPN tunnel. In the other case of connecting to a business partner, you may or may not have control over the device on the other end of the tunnel.
In these articles, we will consider the solution to both scenarios: either you have access to both devices or you have access to just one device. PA-A3 Enhanced ATM Port Adapter Installation and Configuration - Chapter 4:Configuring the PA-A3 [Cisco Port Adapters] To configure the signaling PVC for all SVC connections, enter the pvc vcd vpi vci qsaal command in interface configuration mode.
Note This signaling PVC can be set up on a major interface only, not on the subinterfaces. The VPI and VCI values must be configured consistently with the local switch. The standard value of VPI is 0, and the range of VPI values is 0 through 255. The standard value of VCI is 5, and the range of VCI values is 0 through 65535. Note VCI values 0 through 31 are reserved and do not carry data traffic. Cisco Unified Communications Manager Express - Support. Cisco 2800 Series Integrated Services Routers. General Q.
What are the Cisco ® 2800 Series Integrated Services Routers? A. The Cisco 2800 Series comprises four new platforms: the Cisco 2801, 2811, 2821, and 2851 Integrated Services Routers. The Cisco 2800 Series provides significant additional value compared to prior generations of Cisco routers at similar price points by offering up to a fivefold improvement in chassis performance, up to a tenfold increase in security and voice performance, new embedded service options, and dramatically increased slot performance and density while maintaining support for most of the more than 90 existing Cisco 1700 Series Modular Access Routers, 2600 Series Multiservice Platform, 3700 Series Multiservice Access Routers, and 3800 Series Integrated Services Routers interface cards and modules.
The Cisco 2800 Series features fast, high-quality delivery of multiple, simultaneous services. Q. A. Q. A. Q. Configuring Static Route Tracking using IP SLA (Basic) In today's network environment, redundancy is one of the most important aspects, whether its on the LAN side or on the WAN side.
In this topic we will be covering WAN redundancy with multiple WAN links terminating on a single router. The best and simplest way to achieve WAN redundancy on Cisco devices is to use Reliable Static backup routes with IP SLA tracking. IP SLAs is a feature included in the Cisco IOS Software that can allow administrators the ability to Analyze IP Service Levels for IP applications and services. IP SLA's uses active traffic-monitoring technology to monitor continuous traffic on the network. This is a reliable method in measuring over head network performance. With IP SLAs, routers and switches perform periodic measurements. Users interested can head to our Cisco Routers section where they can find a number of articles covering IP SLA configuration on Cisco routers. Let us take an example of a basic redundant WAN link scenario as shown below: R1# show track.
