Metro Ethernet in RAIL Transportation (MRTS) applications

Dear Sir,
I have a query related to Metro Ethernet technology.
We are into TRANSPORTATION SYSTEMS. We are coming up with a MRTS Project in Mumbai , India. We are at a planning stage at the moment. As per our experience, companies in RAIL MRTS Applications are using SDH technology (MUX and access multiplexers).
Could you please suggest , should we go for METRO ETHERNET of SDH Technology.
Are there any players/ any Metro Projects who have implemented Metro Ethernet ( instead of SDH).

Hi Pankaj
What kinda applications you are going to use and what kinda bandwidth requirement you have in place ?
Also do revert back the number of locations and a bit more onto your topology which mite help to get back with our suggestions..

  • 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.

  • LMS Metro ethernet monitoring

    Hi,
    I'm pretty new with CiscoWorks LMS and need some advices. I need to find a way to monitor metro ethernet links between devices in my customer's network (through DFM and RME maybe). I've been searching through documentation but haven't found anything helpful. My idea was to monitor syslog traps regarding EIGRP and OSPF routing protocols but as far as I can see LMS doesn't have support for this, it supports just 27 different traps. Is there a way to customize LMS so it can react on traps that are interesting for me? To put it shortly - can I monitor routing protocols (maybe through gathering syslog messages and then alerting upon them)?
    Btw, LMS is version 3.2.
    Any advice is appreciated!
    Regards, Omar

    Hi,
    thanks for the advice. I'd like to be able to differentiate alarms between locations in my network. I'm attaching a drawing which presents my network. There are 2 ME links from different providers between bigger locations and edge locations. When OSPF neighborship is lost between router A and router B, meaning ME link x is down, customer would like to receive a message saying 'ME link between location A and location B is down'. When neighborship is up again, customer would like to receive a message saying 'ME link between  location A and location B is up'. In my opinion, the only way to do this is by making as many Automated actions as I have locations multiplied by 4 (2 ME links - for each set and clear events). Please correct me if I'm wrong. Do you maybe have an alternative solution (maybe to differentiate between IP addresses and locations on the application that would collect LMS emails, URL or script results)?

  • 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 .

  • Suggest No. of routers in a single metro-ethernet Vlan

    Hi,
    Just would like to know if there is a recommended no. of routers to put into a single metro-ethernet vlan. The local Metro-ethernet provider suggest 10 routers per vlan but I think 30-50 would be OK ?

    This question is like how many nodes can you put into a VLAN. For an answer to be given your traffic types would need to be known. How chatty are your routers? Are you bridging? What type routing / bridging traffic (non-unicase) might you have on the wire? Baseline data from your environment is important to answer this question. There is no hard fast recommendation for this just as there is none for numbers of nodes in a VLAN or router is an OSPF area. This is completely dependant on your environment.
    Hope this helps,
    Don

  • VPLS and H-VPLS w.r.t Metro Ethernet

    Thanks a lot for the presentations Harot...
    As I'm a bit new to MPLS technology, I have some doubts in my mind so far Layer 3 VPNs are concerned. Let's consider a typical Scenario :
    CE-->PE-->P-->P-->PE-->CE....
    Could u pls tell me where MP-BGP runs (whether in PE to P or PE to CE b'coz somewhere i read the protocol used between PE-CE is MP-BGP and that's why I'm confused) and what is it's purpose. So far I know MP-BGP is run in order to make the VPNv4 routes unique i.e IPV4+VPNv4. I would highly appreciate ur feedback if u explain the layer 3 concept entirely protocol wise...i.e IGP, MP-BGP in a MPLS domain. What I know so far is CE-PE protocol can be anything right from static to BGP. P-PE is MP-BGP.
    Kindly pl. correct me wherever I'm wrong...

  • 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
    J.

    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.

  • Best way to detect failure in Metro ethernet networks

    Hello ,
    I am working for a well known provider and I am currently migrating one of my client from Frame-relay to Metro-ethernet link .
    I am actually looking for advices on what sort of mechanism to implement to detect a failure in the ME parth .
    As you probably know , failure on one of the links might cause the CE-SWITCH-PE interfaces to stay up/up and the network will not neceseraliy start converging .
    So far I have implemented BFD along with IP SLA route tracking , I am happy with BFD but the IP SLA is acting "weird" .
    - IP SLA ICMP tracking rely on ICMP packets and was too sensitive to packets lost
    - We switched to ip route sla tracking but I am still unsure about the best way to use or implement this .
    Is there some sort of best practices available somewhere for this ?
    thanks ¨
    T

    Hello Thomas,
    From what i have seen BFD is best bet as it allows to relax the L3 protocols timers ( BGP / any other protocol used between CE- PE ). Another option is to have gre tunnel between the PE - CE link and track this tunnel interface.

  • Metro Ethernet Design With Redundant Head Ends

    We're getting ready to turn up some metro ethernet circuits that were just installed by AT&T. AT&T has provided a VLAN for each remote site (so each site has its own VLAN), and those VLANs are trunked to our head end switches (Cisco 3750 Metro Switches).
    I'm struggling with the best design for IP routing. We currently use OSPF on our internal network, and I was going to extend OSPF to our metro solution as well, but I'm not so sure now.
    I don't want routing to occur directly between head end #1 and head end #2, we already have redundant paths within our corporate network, and allowing our two head ends to route between each other via our metro ethernet solution is not what we want. However, running OSPF on each of the VLANs which have been provisioned for us would permit routing between the head ends.
    We simply need to allow redundanny for our remote locations in the event that one head end were to fail, all of the traffic to/from the remote site would be routed through the head end which is still online.
    Anyone suggestions on the best routing design for this situation would be greatly appreciated. I've attached a network diagram to make things clear. I believe I can also go back to AT&T and request one VLAN that includes all sites if that would simply things. I just need to make sure I can still do our traffic shaping because the remote sites are only 10mbps and the head ends are 1gbps.
    Thanks,
    -Steve

    just at a glance it looks as if you should be able to have stp on and setup 1 site as primary and other as secondary

  • 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

  • Transport of application table & data

    Hi guys,
    I need to transport an application table and I'm getting error:
    "Fill table key for table XXX only up to position 003 only".
    What does it mean?
    Is there a problem the table contains data?
    I need to transport table including all data from it. Is there any way how to achieve it?
    The table is cross client.
    Thanks,
    Olian

    Hi....
    We can use this procedure to transport table entries...,
    Create a TR in SE01.=>Display TR=> Place the cursor on the TR=> menu=>Request/task=>Object list=>display object list=>change=>Add new rows=>
    Here give program ID as R3TR, objects as TABU and object name as ur table name. Press enter. U may get a message. Just close it and double click on the table name. In the Next screen press insert icon. Here u can specify the Key(Table key values) If u want to transport specific entries.
    If u want all entries to be transported then simply give * and save the TR. Now if release this TR it will transport all table contents to the higher system.
    Thanks,

  • Traffic Shaping on 6880 between sites over metro ethernet

    Hi
    I have a new dual site setup with 6880s at the core at one side and 3650 stack at the other. We have a 200mbps ethernet solution from our service provider but on testing we are maxing at a bit over 100mbps, iperf tests directly on the link are giving 200mbps so I need to apply some shaping to get the full usage from the link. In the past I have used srr bandwidth on metro switches but the 6880s don't support this. So I assume I need to setup  policy maps and apply to the physical interface? The interfaces are layer 2 trunks and we are stretching vlans between the sites. E.g. siteA has vlan20 and site B has vlan 20 over the metro ethernet service, site b is layer2 only and all routing and services are provided at siteA
    Is it as simple as this? It seems too easy :) So I may be missing something. I just apply this on the physical interface at each side?
    policy-map POLICY-S2S-200MB
    class class-default
    shape average 204800000
    policy-map POLICY-S2S-200MB-IN
     class class-default
       police cir 204800000
         conform-action transmit 
         exceed-action drop

    int gi1/1/1

    Your input would due treaty appreciated!

    Ah, well that's great!  (Hmm, now I wonder if same feature is available on 6500 with sup2T or 6807.)
    In that case, your output policy might be just as simple as what's in your OP.  Cisco isn't really clear whether all their shapers (or policers) are counting L2 and L3 or just L3. I suspect many just count L3. If that's true in this case, you may need to shape about 10 to 15% slower to allow for L2 overhead (this assuming your provider is providing 200 Mbps of "wire" bandwidth.
    If you're able to shape on the other side, then there should be no need to also police the ingress.  Also, assuming provider limits bandwidth, there's no reason to police ingress at CIR rate.

  • 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.
