How To Create Fiber Optic Network
Jul 23, 2012When it comes to fiber optics my knowledge is very limited. All I know is that they can carry data at high bandwidth for a long range at blazing speeds etc.My boss has asked me to link several buildings to the network and I am led to believe that joining them through fiber optics to be best since we are expecting a lot of data traffic between.I have done the normal RJ-45 networking with Gigabit networking in my organisation but need your assistance on how to join each of the buildings through fibre optics.Draw up the fiber optic lines from the main building to each building.All the buildings have Gigabit Cat6e cabling and network in each.I am planning on using a single mode media converter to convert the end of the fibre optic to the normal RJ45 connector and plug it to each switch at each of the ends of the fiber optic cable .I don't even know the gadgematics required except for the cables them selves, crimping tools, the media converter. There is about 300-400 metres in between of each building from the main building.Also, I believe that we need to create cross over cables as in the normal way we do in connecting 2 switches.

Location 1 is in the south, 2 is in the middle and 3 is in the north pretty much in a straight line.Should we run one fiber optic cable from location 1 to location 2 and another fiber optic cable from location 1 to location 3 or is there a better way? Maybe we can run from 1 to 2, 2 to 3 so that location 2 acts like a hub.Is there a way to just run one fiber optic cable from location 1 to 3 and along the way somehow splice that cable to go to location 2

Apr 1, 2012I'm working on a new network design for my company. We're expanding and opening some more offices and satalite sites. We're a UK based company but opening some US sites.We have a main UK office (Office A on the diagram) a call centre (Office B) and then two buildings on another site (Office C). The USA offices will be very small and only require a couple of computers, hence the small IP allocation. I have marked the IP addresses of the links on the diagram, I intend to use 3560 switches for all the switches marked and all links will be layer 3 to route multiple VLANs from each site to each site (where permitted). question is this: How do I achieve this in the switches? I'm thinking that OSPF is the way forward, is this right? I want to do as little configuration on the switches as possible to allow for dynamic updates of the network (i.e. I don't want to add static routes for everything).

Cisco WAN :: 2960 Network Design Query
Aug 22, 2011I am in the process of planning our new network. Our business is changing from hosting its own data centre, to moving it to a professional facility. We have 120 users, over 100 servers (physical and virtual) and three sites (main premise, data centre, dr site). The new network will connect all three. Our new WAN links are almost ordered. We will be making use of a managed MPLS IP VPN, with a 100M access rate at each site. I am currently focusing on the desing of the network at the main business premise. We have a significant investment in Cisco 2960 & 3750 switches and Fortinet firewall appliances. I plan to re-use these in the design.
Our current LAN is very flat and I want to segment the network. My plan is to create a number of VLANs, enable the Inter VLAN routing on the 3750 and then attach the 3750 to the Fortinet appliance which will provide stateful firewalling and traffic policin based on the VLAN (subnet) addresses. It is important that the traffic be routed as quickly as possible from this site to our prod and dr data centres.The 2960's act as the access layer, the 3750 as the distribution layer. The 2960's will connect via port channels (layer 2) to the 3750's and the VLAN interfaces will be configured on the 3750.
I was then planning on creating a VLAN on the 3750 to connect to the Fortigate appliance with a /29 address to limit the addresses used whilst also providing some flexibility for any future design changes.I want to implement a little security between the VLANs on the 3750 switches. I have a question about this coming up.I then plan to use the Fortigate appliance to do basic traffic policing based on source/destination addresses.
The WAN routers will connect to the Fortinet appliance on a Gigabit copper interface. The WAN routers will run HSRP between themselves and only one router will be active at any one time. The failover will be managed by the Fortigate and Cisco routers.I plan to define those addresses hosted at the other data centres and associate them with the interface associated with the WAN.I will then define the routing on the firewall for the two other data centres through summary routes for each of the sites. We will run static routing from the Cisco 3750 to the Fortigate and Fortigate to WAN router. We have no other networks/sites and won't have any others in the future.
Cisco :: Network Design Task - None Of The Domains Will Be Able To Communicate With Each Other?
Mar 6, 2013I've been tasked with designing a network consisting of 3 separate broadcast domains with each one representing a separate business accross 3 separate floors. None of the companies should be able to communicate with each other.I've been told that the design should only represent the first 3 layers of the OSI model so I'm only looking at Cabling, Switching and Routing.
I don't expect you all to tell me exactly how I should do this, however I just need a starting point. My main issue is with routing. I'm aware that each port on a router represents a broadcast domain so if I use one router, 3 broadcast domains, does that means that none of the domains will be able to communicate with each other? Should I use more than one router or can i get away with one? Also just so you are aware I've been told not to use VLans and each broadcast domain must have its own ip address schema.
Cisco WAN :: 2921 - Network Design With BGP And Active / Passive ASA's
Mar 1, 2012The following diagram is showing what I "Plan" on doing or "Hope" I can do. This is the most complicated deployment I have taken on in my profession, and Honestly it is very exciting, but had some questions.
1. The network between the ASA's and Routers, is that suppose to be a Private network or Public Network? I have to assume Public because I want my ASA's to take care of the NAT.
2. ASA's are runing single context Active/Standby so what way will the ASA push out going traffic?
3. The routers need to know about each other in a BGP configuration, correct? We accomplish this using iBGP so will that traffic need to be allowed through my firewall to allow the routers to share that information, or should these routers be talking to each other outside the firewalls?
Is this design possible? I am sure there are limitations as always, just trying to wrap my head around the flow of traffic and where to start.
Additional Details/Requirements -
BGP routers are 2921's that I have control of. Both routers have 4 port GigEtherswitches in them.
ASA's are Active/Passive and cannot be Active/Active due the limitations of the Active/Active Design (VPN limitations)
Both ISP's must be used for outbound traffic, I would like to be able to load balance, but can send some traffic one way and the rest of the traffic the other way based on Routes.
ISP's are not Symentrical, one is 50mbps and the other is 250mbps.
All NAT should take place at the ASA's
Additional Questions:
The routers that have gig etherswitches, can they run HSRP?
Should I be putting Layer 3 switches between the routers and the ASA's instead?
Where should I run my iBGP communication for the routers?

Cisco Switching/Routing :: 2960 G / 1941 - Network Design
Jun 14, 2012I have been recently asked to design a network. What I have for equipment is four 2960G's and one 1941 router. One switch is a root switch and the other three will have end devices on them.I have decided on three V lans to go with: VLAN20 Data, VLAN30 ISCSI, and VLAN99 Management each with seperate trunk links and redundancy (see picture below).
I have a seperate trunks for each V lan using the switch port trunk allowed. With exception to the Data V lan.My design has the Data V lan as the native because it is going to be receiving untagged traffic from the external network. I have set up inter v lan routing on the 1941 via sub-interfaces to allow them to talk to each other (or because of allowed they cannot?). I have one port coming from my router to my switch via Ethernet cable which is my bridge out. I have my external port doing a NAT translation for my inside addresses and a Default route set up ip route 0.0.0.0 0.0.0.0 gig0/0. I am using rapid- PVST to prevent loops and provide my zero downtime convergence when a link goes down. As it stands right now I cannot talk out of my network or inside of my network.
You can see it is highly redundant and I do not want to change it. This network is going to be deployed but there will never be anybody physically there to manage it which is why I made it as redundant as humanly possible.
Cisco Firewall :: How To Design ASA 5510 Failover For Process Control Network
Mar 19, 2013I'm currently working on setting up 2 ASA 5510's with redundancy/failover. I'm not an expert when it comes to the ASA's so I'm not 100% sure if I can do what I need to.I have 2 inside networks that need to remain separate, a DMZ network,and an outside network. Since each network connects via ethernet to one of the 4 ethernet ports on the ASA 5510's, all 4 ethernet ports on the ASA 5510 will be in use. If I wanted to setup one firewall as Active and the other as standby, how would I go about doing that? Do I need a direct ethernet connection between the 2 firewalls to use something such as HSRP? Or would the Standby firewall be able to tell if the Active firewall is OK since they would both be connected on each of their interfaces to the same networks?

Apr 11, 2013remote location on MPLS circuit terminated on a Cisco router that has Internet connectivity through Central Site router. We are installing a cable modem at the remote location that is to be used as the Primary Internet Connection but still be able to use Internet through MPLS if the cable Internet goes down. We want the failover/fallback to be handled automatically.
We have an ASA5505 for the cable Internet which then feeds into the ISPs modem.
At first I was thinking about getting a module for the remote router so the cable Internet could be terminated on the remote router as well but that introduces a single point of failure. I would also like to firewall both the MPLS and the cable Internet but if I do so on the ASA there is another single point of failure.
Cisco Switching/Routing :: 3750 - MSTP Design And Network Diameter Limitation
Jan 25, 2011I am just browsing and looking for a solution to converge my multi-vendor switched network and bring some redundancy to it as recently
we managed to get a redundant links. I have a need to change core switch to Cat3750G, which has Per-V LAN-RSTP+ on board, but tests have shown that it won't be compatible with some other proprietary per-V LAN RSTP solution other vendor's switches use currently.
So, I thought maybe standard-based MSTP design might do the trick. I've made some tests and got some weird and unstable switching result. I have two topology rings with a core switch in the center. Every ring has about 10 switches, so practically network diameter may vary from 5 switches (when spanning-tree converges in the center and I have a blocking port somewhere int the middle of the ring) to about 10-11 switches (if a I have link failure on any of ports right at the core switch). I disconnected one port from core switch to eliminate a possible switching loop while I will be configuring new MSTP design. Then I started enabling MSTP on all the switches staring from core Cat3750G to MSTP, one by one, placing all switches to the same MSTP region, and placing all V LAN's to default MSTI0(CIST) cause I don't need to organize any separate MSTP instances for every V LAN or for group of V LAN s. When I turned MSTP on on 7th or 8th switch in the chain (cause I had a physical chain when I disconnected one port out of redundant ring) I got all switches "flapping", storming and flooding the network with broadcasts. Even when I had one redundant port disabled.
I have no idea what I am doing wrong. I noticed that Cat3750G has an option that defines a possible network diameter which actually automatically changes some hello, max age etc. attributes according to diameter specified. When I defined a maximum network diameter of 7, if didn't change anything: I still have hello timer of 2 sec etc. I've been wondering if the maximum network diameter has something more than just a "variable" to fine tune hello timers etc? Maybe I won't be able to use MSTP in my network which might have diameter more that 7 switches. Or maybe it was a mistake of placing all the switches to the same region and all the v LAN s to the default MSTI0 (CIST) and I should configure one MSTI per V LAN or per some group of V LANs and subdivide my switches to few MSTP regions?
My topology briefly looks like this:
+--SW1----SW2----SW3---CORE---SW4---SW5--SW6---+
| | | |
+---SWxx---SWxx-----------+ +------SWxx-----SWxx----+
As I said, each "ring" has about 10 switches connected side by side.

Cisco Wireless :: 1242AG - Extend Network That Cannot Be Reached By Copper Or Fiber?
Nov 18, 2012I have two Aironet 1242AG access points. Currently, one of those access points is in use with an SSID of ABCWIFI.
I want to extend the wireless network to an area that can't be reached by copper or fiber. So, I've purchased another 1242AG. What I'm not sure of is how to configure it. Should I use it as a repeater or in a root-bridge/non-root bridge configuration?
What I'm most confused about is, what do I do with the second radio? Do I use the 5Ghz as the "backhaul" with a completely separate SSID and then broadcast the normal SSID over the 2.4Ghz? Or, do I even use the second radio at all? The key is that the same SSID is used in all locations because the devices in use need to move seemlessly between access points
