Diflucan 150mg pills $82.00 This tutorial is a continuation of the virtual voice lab series. Diflucan 150mg pills $82.00 Unfortunately, diflucan 150mg pills $82.00 the virtual voice lab has been a “work in progress” much longer than I had hoped it would be when I started it two years ago. Diflucan 150mg pills $82.00 In this tutorial, diflucan 150mg pills $82.00 you will add a new router to your GNS3 topology. Diflucan 150mg pills $82.00 It will connect it to the HQ, diflucan 150mg pills $82.00 BR1 and BR2 routers to simulate an Internet connection and the Public Switched Telephone Network (PSTN).

Diflucan 150mg pills $82.00 There is one caveat to this PSTN simulation… GNS3/Dynamips is not capable of simulating traditional analog or digital circuits. Diflucan 150mg pills $82.00 We will be simulating an Internet Telephony Service provider (ITSP). Diflucan 150mg pills $82.00 ITSPs have become increasingly popular in the past ~5 years. Diflucan 150mg pills $82.00 Basically, diflucan 150mg pills $82.00 the PSTN router will route incoming calls to the branch routers and received outgoing calls from the branch routers over a SIP or H323 trunk.

 

Diflucan 150mg pills $82.00 Placing the “PSTN” router in the topology and configuring IP addressing will simulate an Internet connection for the branches but it is just the first step.  The call routing will be accomplished using the Cisco Unified Border Element (CUBE … formerly IPIPGW) feature or H323 Gatekeeper in other tutorials. Diflucan 150mg pills $82.00 As a side note, diflucan 150mg pills $82.00 VPN’s and other technologies can be tested with the simulated Internet we created.

Diflucan 150mg pills $82.00 Here are the steps:

  1. Add a router to the GNS3 topology.
    You will need an IOS image on the router that supports CUBE, diflucan 150mg pills $82.00 Gatekeeper or both.
  2. Change the hostname e.g. Diflucan 150mg pills $82.00 “pstn_internet” (optional)
  3. Add an NM-16ESW module to the new router
    1. Right-Click on the new router and configure
    2. Click the ‘Slots’ tab
    3. Add an NM-16ESW module to the router

  4. Connect the following interfaces to the existing branch routers
    • pstn_internet f0/0 -> Port 5 on the HQ Switch
    • pstn_internet f1/0 -> f0/1 on HQ Router
    • pstn_internet f1/1 -> f0/1 on BR1 Router
    • pstn_internet f1/2 -> f0/1 on BR2 Router
