Metro ethernet connectivity

metro ethernet connectivity is to be provided between 5 remote location and one central location.remote location has 2811 router and central location has cisco 7606 router.Now how to accomplish this connectivity?..what is the configuration?..ME connectivity is to be provided by ISP and they are using cisco 3550 switch....
help me out soon

Dear Friend
If you want to deploy and use L2 VPN service you should
define whst is he type of core
do you want to use L2 VPN service based on IP or MPLS?

  • Customer Equipment for Metro Ethernet Link

    Hi All
    It has been some time since I utilised Cisco network kit to provide private circuit point to point connectivity and I wonder if someone could give me a little guidence.
    The customer is shortly to implement a new 100Mb Metro Ethernet link to connect two of their branches. They initially intend to use the link for data only traffic but eventually will want to route VOIP traffic across the link so bandwidth management and QoS will be essential components. It is unlikely that further links will be added to this link so built in expansion of the chosen routers may not be required.
    Budget will be an issue on this so I would appreciate any advice or recomendations.
    Thanks

    Hello James,
    I think it would be better to get in touch with your Cisco Account Team as this question cannot be answered on a forum post.
    Thanks,

  • Metro Ethernet implementation questions

    I am planning a Metro Ethernet upgrade for a network I manage. This is the first time I’ve implemented Metro on any network. I’m looking for some suggestions and answers to a couple questions regarding this upgrade.
    The current network is Hub and spoke connected by copper lines to 17 different locations from a DS3 @ our HQ. HQ also has a DS3 to the internet which the branch locations go out for internet. At our branches we have a private and public network on different subnets. Each branch location has either a T1 or bonded T1 connected to a Cisco 2801 router then to Netgear PoE managed switch(s).
    The upgrade of the DS3 for internet is going to 100 meg. The data side will also be 100meg at HQ, 10meg to our small locations and 100meg to the large.
    My question is what do I need to be aware of on our existing network that must change to get this working?
    1)      Will I simply go from the layer2 Metro Switch to our router?
    2)      Should I remove the router and go directly to the Netgear switch?
    3)      Do I need to VLAN the private and public networks?
    4)      Do I need to change routing tables?
    Thoughts and/or suggestions welcome.
    Let me know if more information is required to assist in answers.
    Thanks

    Hi,
    I think it would be better to include Cisco Account Manager/SE for this upgrade, they can guide you better and can come up with LLD for this upgrade, otherwise upgrading your 17 sites without proper planning can cause you serious issues.

  • Metro Ethernet Design question

    Hello,
    I was wondering how service providers guarantee their security protection in the Metro Ethernet model, especially when Internet is one of the applications used over the Metro network.
    For example: The customer edge switch (3550) is connected directly to the service provider aggregation layer(either Cisco Catalyst 4500 and 6500 Series switches ) .
    In the network core, Cisco 12000 or Cisco 7600 Series routers.
    So where is the security devices in this architecture, where is the firewalls, the IDS/IPS, that protects the service provider core from any threats.
    Providing the customer with Internet in Ethernet switching technology the service will put the provider in a vulnerable position.
    Am I thinking wrong here?

    Hi
    The CE will be hardened using storm control both multicast as well as broadcast on the ports where the end users are connected.
    About the accesiability between the other users who are connected on the ports of same switches you have switchport security coded which will take care of the access violation part.
    Also the maximum no of MAC address which can be permitted/allowed over the ports.
    This inturn will send u a trap and can shut the port if theres any violation detected on those ports..
    In the next layer where u say 6500 or 7600 u will have FWSM modules which will be taking care of filtering and other funtionalities which is very much similar to a standalone PIX firewall.
    you can have redundandcy or even load balancing with
    the FWSM modules over there in the 6500 switches.
    And ofcourse the IP addressing schemes deployed would be in private scopes and will have either NAT pools or PAT enabled in the FWSM.
    you got to have more n more ACLS on all the devices to mitigate the general known worms/virus or their variants in the network applied in applicable points.

  • Comcast Metro Ethernet Setup

    We have one customer with one ASA and one 3750 switch in headquater. 6 1801 Routers in 6 branches.
    All connected via MPLS/BGP provided by ATT. And it was terminated at one port on 3750.
    We plan to replace that with Metro Ethernet Hub/Spoke topology since the customer mentioned each office never talks to each other. Later on we found they have IP phones do need to talk with each other at branches.
    Question - can we still use the MetroE service but configure routing to make each office talk with each other and how that would work?? I would assume some routings on 3750.
    Any info is appreciated. thanks!
    Ben

    Hi Ben,
    It will work for sure since this is what ( in a much more complex scenario) we are implementing in our company since ab few months. Just take care of defining data and voice subnets as technically unrelated so to be free implementing very flexible and easy to manage routing policies. Is ATT providing L3VPN or what?
    Hope to help

  • Metro ethernet, Ethernet protection ring.

    Hi everybody.
    I hope everybody is doing great.    A quick question for you guys.
    Let say we have Ethernet switches connected in a ring .We want to use Ethernet protection ring for loop avoidance and faster convergence.
    One of the switch will be RPL owner, and of the link in our ring will be chosen as RPL link.
    1)My question is what is the criteria for RPL owner selection and RPL link?  (  For e.g  in STP, we use lowest bridge priority for root bridge)
    2)  Is Ethernet protection ring provide an alternative to stp when we switches connected in ring toplogy  and fast convergence is required as is the case with metro ethernet commonly ?
    Have a great evening.

    As Peter wrote, Metro Ethernet is a vast topic.  However, from a non-provider perspective, the idea is to allow interconnecting widely physically separated (your) site networks just about as simply and similar to connecting your LAN together at one of your sites.  I.e. you just connect different (your) site devices with an Ethernet connection, and you use that connection pretty much like you would any other Ethernet link between your devices.
    From a carrier or MAN provider perspective, running a widely distributed, multiple customer Metro Ethernet (or a carrier Ethernet) network, you'll want some features not found in (as you say) "normal" Ethernet equipment.
    What's different about Metro Ethernet switches is they generally offer features not found in "normal" Ethernet switches.  Again, from a non-provider perspective, you often only need/desire a few additional features (and for that reason, it's not uncommon for non-providers to use "normal" Ethernet switches with Metro E - I've also seen Metro E switches used with "ordinary" LAN Ethernet networks).  From a provider's (carrier's) perceptive, you'll really want more features.  Because of these two perspectives, you'll often find Metro Ethernet switches marketed to non-providers, and Carrier Grade Ethernet switches marketed to the MAN Ethernet providers.

  • Metro Ethernet

    Hi all
    iam trying to Build metro Ethernet in my own town
    I have office with a distannce of 10Km
    i want to bring them in metro ring and connect failover ring
    So i have 5500 Switch at central end
    and I have 2 3750 Switched with LH Giga Module SFP in it 2 ports
    Now iam confused, what kind of CARDs i need to Buy for 5500 so i can integrate with 3750SFP ports with 5500 with ring protection
    I have in 5500 Supervisor III with 100MB MMF,
    What kind of Modules need to connected with 3750 ( situated other 2 office)
    so all 3 going to be in ring protection
    help will be appriciated
    hari

    yes, you can integrate with 3750SFP ports with 5500 with ring protection .
    CISCO WS-X5302=. Catalyst 5000 Route Switch Module will be module that can be used.

  • Building metro ethernet using cat3750

    Hi,
    I am Mazlan and work for one of ISP in Malaysia. We would like to discover metro ethernet technologies.
    We would like to use our current backbone network to create this metro network and we are planning to use cat3750.
    The design is something like this.
    R1--cat3750--RA--[WAN}--RB--cat3750--R2
    R1 and R2 is in different location but will be running on same VLAN (with help of cat3750). Let say there is customer connected to R1 and their branch at R2, they will only feel they are in same LAN, but actly they are in different location.
    We need some opinion of builidng this network. I need help for the configuration in cat3750 as well in the router. We have no experince in this technologies.
    Perhaps somebody whos is interested to help me out can email me at [email protected]
    Your help is highly appriciated.
    --mazlan

    The Catalyst 3750 switch supports IEEE 802.1Q tunneling and Layer 2 protocol tunneling.

  • Bellsouth Metro Ethernet -- is it QinQ?

    I have a customer who has bought some connections from Bellsouth's Metro Ethernet product. I am having a tough time getting someone at Bellsouth to give me any information about the product.
    Are they just using QinQ (802.1q tunneling) to make it all happen? If that's the case then I should just trunk to them with 802.1q and not have to do anything else, I believe keeping the native vlan 1 should even be fine. If anyone knows anything about this or has connected sites using the Bellsouth metro-e product please let me know.
    Brian

    Hello,
    looks like it is Ethernet over SONET, with a possibility to migrate it to EoMPLS:
    "Currently BellSouth uses a specialty Ethernet switch to support its shared multipoint offering, but that may change. "We're converting to more of a general purpose device that will be part of our MPLS network and will deliver Ethernet and other services," hints Kaish.
    Some carriers have implemented shared multipoint services directly over fiber, which means that those services do not include Sonet restoration capability, effectively limiting them to non-critical traffic. But BellSouth's metro Ethernet network is Sonet-based and customers can leverage Sonet's restoration capabilities, Kaish says."
    http://www.findarticles.com/p/articles/mi_m0DUJ/is_13_107/ai_108408900
    Another source of information supporting the statements above:
    http://newsroom.cisco.com/dlls/2004/prod_070604.html
    In any case this does not mean straight forward, that you can use the service to setup trunks between your switches. This depends on the interface configuration of (presumably) the 7600. They might restrict you to dot1Q with one VLAN or even to plain ethernet.
    Hope this helps! Please rate all posts.
    Regards, Martin
    P.S.: have a look at http://www.metroethernetforum.org/presentations/SC2003_BobSmithEntNet.PDF which should answer many questions! Especially they state "Dedicated Ethernet supports VLAN tagging" - sounds like setting up a dot1Q trunk with them will be supported.

  • Integrating Metro Ethernet to DSLAM

    Dear friends,
    I am very new to Metro Ethernet and currently I am facing a solution problem. The thing is my customer want to deploy a MEtro Ethernet Network, which in turn they should be able to interconnect to a DSLAM network. The specific customer requirements are below, i am getting smoke out of my ears working on this.
    1) Deploy a Metro ethernet network and integrate it to DSLAM network
    2) Design should be such that customers of my customer (SP) can change his bandwidth limitations. For eg: if the SP's customer wants to have a video conferencing for a few hours then say for some 4 hrs he/she should be able to change the provided bandwidth. The SP should be able to monitor and bill for this.
    3) As a section of this Metro Ethernet solution a part should be able to provide video,data,voice and other near future application on EXISTING RJ 11 telephone wire connection at the customer places.
    I have only 1.5 yrs experience in networking and that too only on configuring and installing routers,RAS FW switches etc. I have never been to Solution providing and this is the first one. I dont want to lose it. can any one help ???
    Pleeeeeeeeease !!!!!!!!!!!!

    Hi,
    Your requirment seems to be preety simple as far as metro ethernet deployment is concerned.
    Suggest you to look for Cisco Service Selection Gateway ( SSG ) feature set on Cisco 72xx,73xx,10K series routers. With SSG coupled with SESM , users have flexibilty of change the bandwidth on the fly and SP can bill him accordingly.
    Apart from the requirement of bandwidth change , i would like to make a point that your customer should go for ADSL 2 or 2 + for catering triple play services ( voice,video and data )
    As far as metro e network is concerned i would have gig ethernet bandwidth in the backhaul .
    If the customer is not so Cisco Savvy , you can look for Juniper SDX platform , which supports COPS !!! ;)
    you can reach me a [email protected] for any assitance required .

  • Help with setting up Metro Ethernet

    Can someone please help and give suggestions and possible configuration options for setting up metro ethernet in the following senario:
    Will be setting up ME between headquarters and three remote branch offices. Each remote branch will be provisioned to 10MB, and the headquarters will have one link for the aggregate provisioned to 30MB.
    My questions, we will have routers at the remotes, but how will this terminate at the headquarters? Do we connect the one ME aggregate connection to a router, or to a L3 switch? And how do you configure the headquarters devices to separate the traffic? Do you use sub interfaces like in frame relay? Please provide a sample config if possible.
    Thanks

    HI,
    Assume you have 3560 SW at your HQ and where you can terminate the ME circuts.
    Configuration in Switch as:
    3560SW#sh run int Fa0/5
    Building configuration...
    Current configuration : 123 bytes
    interface FastEthernet0/5
    description ***************
    switchport access vlan 40
    switchport mode access
    end
    Create a SVI interface at the Router, the configuration is as:
    7604-Backbone-RTR#sh run int Vl40
    Building configuration...
    Current configuration : 119 bytes
    interface Vlan40
    description *********
    ip vrf forwarding 1234-NAME-MESH
    ip address xx.xx.xx.xx 255.255.255.252
    end
    In the above configuration, VRF is applied on Interface to make the pefix unique across the Backbone.
    is it here at the remotes where I will configure the "sub-interfaces"?
    A. Yes, the case for remote is same as that of HQ.
    Pls Rate if HELPS

  • UDLD in Metro Ethernet

    Can i use udld between two switches connected in a metro ethernet network? My idea is use the udld to monitoring the health of the two physical interfaces that are doing part of the ether-channel. Each switch in the Data Center Interconnect have two links of different service providers and in the case of a failure in the Service Provider network, the interface of the channel goes down.

    Hello Julio,
    sorry for late answer
    you can try to use LACP to have LACP control frames sent over each member link.
    Lack of reception of LACP frames will move a link out of the bundle
    in metro ethernet environment the better tool is ethernet OAM CFM mode that can involve SP nodes in the performed tests.
    Hope to help

  • QoS on metro ethernet links

    We recently got a metro ethernet link (45Mbps) between 2 of our offices.
    Currently we do not have any QoS services from the provider on this link.
    I want to implement QoS over this link. Should i treat this as a normal P2P link and do the QoS or should i also need to ask the SP to do some sort of QoS in their MEN.
    Does it really matter to have the SP do QoS as well
    Note:- I will be using the link purely as a L3 P2P link
    Thanks in advance
    Narayan

    You would need the QOS on the MAN connect as well. Even though you are running a L3 P2P link you are traversing multiple L2 hops.
    And where there may be contention by others traffic contending for the resources.
    I believe in most cases your SP's 4 to 5 Classes would be good enough. Still you may want to understand his classes and also may want to negotiate the SLA terms.
    Once this is taken care you can simply ask him to trust the incoming DSCP on the attachment circuit at his UPE.
    You may also have to configure incoming DSCP trust on your Metro-CPE link which connects to you internal core routers.
