Dot1q between two routers connected via 2950

Hi,
I have two 7200's connected to a 2950 (FE 22 + FE 24 - Both configured as trunks).
On the 7200's, I have the following:
7200-A
interface FastEthernet0/0.23
encapsulation dot1Q 23
ip address 192.168.1.1 255.255.255.252
no snmp trap link-status
7200-B
interface FastEthernet0/0.23
encapsulation dot1Q 23
ip address 192.168.1.2 255.255.255.252
no snmp trap link-status
2950:
interface FastEthernet0/22
switchport mode trunk
no ip address
duplex full
speed 100
interface FastEthernet0/24
switchport mode trunk
no ip address
duplex full
speed 100
But I cannot ping between the two routers?

7200-A has dot1q ints for servers connected to the 2950 (Access Ports)....these are all currently successfully trunked down FE24
I want to connect 7200-B to 7200-A, and have dot1q Ints on both routers(As /30's) that can communicate (They will be used on 7200-B as Internet gateways for VRF's (With IP Nat enabled)....I was hoping that by having 7200-B connected to 2950 FE22, and configuring that port as a trunk also, that the dot1q ints on both routers could talk.
vlan 23 does exist on 2950, and is being trunked on both FE 22 + FE 24
I dont have any spare FE ports on 7200-A, hence the reason for me connecting 7200-B to the 2950.

  • Load balancing between two routers

    I have two routers connected through the LAN connection. The first one is using as routing protocol EIGRP, the other one is part of the managed service and I do not have access to it. I would like to make a load balancing between the two of them by redistributing the static routes in EIGRP. When I tried this, I am loosing the EIGRP entry for this route in the routing table. I would like to have both of them , so we could have traffic sharing. I appreciate if you give me any hints.

    Raju,
    you have two choices as far as I can see. If you want to use static routing over the WAN to your branch, you could duplicate your static routes to the branch and point them to the secondary router. You will have two identical sets of static routes in the primary router, one set pointing to the WAN interface and the other one pointing to the secondary router.
    ip route x.x.x.x "WAN-interface"
    ip route x.x.x.x "secondary router"
    ip route y.y.y.y "WAN-interface"
    ip route y.y.y.y "secondary router"
    etc.
    As a result the primary router will have two routes to the branch and will load-balance. If one next-hop fails (either the WAN interface or the secondary router), only the other will be used. If the next-hop comes back up, load-balancing will resume.
    The other choice would be to use EIGRP over the WAN, and make sure the two routers become EIGRP neighbors. Then you can use the "variance" command to achieve unequal cost load-balancing between the two routers. Let me know if you need more information about this, but i think static routes will be sufficient in your situation.

  • Routers connected via serial subinterfaces(for non VPN internet service in a mpls network)

    I have conected two cisco 7200 routes via one serial interface.
    I am going to create two subinterfaces in each of them assign them IP address and connect them via (two BGP neighborship)
    the fact is that they cannot even ping eachother though they are directly connected .
    1. interfaces are no shut
    2.L2 protocol is HDLS on both sides
    3.the IPs are in the same subnets .
    the question is how to connect two routers with serial sub-interfaces.?
    this is my config on both routers , only the IPs are different:
    int ser 1/0
    no shut
    encapsulation hdlc
    clock rate 64000
    int ser 1/0.1
    subif)#ip add a.b.c.d x.x.x.x

    Hello Gabriel,
    Instead of using the HDLC, use frame-relay encap. Make one side as DCE. Use same DLCI on both sides.

  • Wireless Connection between two routers

    Ok. I own two houses seperated by a driveway going to both garages. I have cable internet access linked to a Netgear WNDR3300. That router is sending a signal to a wireless PC, 2 Laptops, and my Mini when needed. My signal in the 2nd house is REALLY weak.
    I have a WRT54GS v4.0 sitting around and it to connect to the netgear and then resend a wireless signal to the wireless laptops around the 2nd house. can I do this? if so. HOW?

    Is your Linksys Router is connected hardwired to the Netgear Router ?
    If your both trhe router is connveted via cable...you can get the wireless signal from both the router.However your purpose will not get resolved because you want to repeat or extend the signal.In my opinion you may get a wireless Range Expander to resolve your Problem.

  • Sharer folder issue between two directly connected PC

    Dear All, I have an issue regarding folder sharing. need your help to resolve this. the scenario is
     two PC's are connected directly to share a folder, to open *.mdb file of a accounting software. this problem start when I moved windows XP PC's and installed windows 7 64 bit PC's. there is no compatibility issue as I run the same software on other
    locations
    PC A (192.168.1.200) has that *.mdb file and PC B (192.168.1.100) has to open this file through a network.
    when I configured the folder share  and network setting, all done well and PC B can connect with PC A and that software work well. After two days, when we start the software at PC B, its not responding when  it try's to open that database file.
    while analyzing, I found out that PC B can open the share folder of PC A but when open the desired database folder explore starts not responding and need to quit it by force. I also tried to share another folder of PC A but results are same.
    PC A run the software with out any problem.
    It seems like network issue, so I check the cable with cable tester, found it good, than I check the connectivity by ping command, it giving me <1ms time. but still change the connectors.
    the hard part is that, this share folder issue arises 3-4 days a week and 2-3 days it works well, and this is happening from last 28 days. I mean, one day we start the the PC B and use the software via network, the next day we start the PC B and we don't
    able to use the software,..strange.
    I also change the cable connection from cross to straight as both new PC's have gigabit Ethernet but results are same.
    I already contact with software company, as per them its network issue as we can use the software on local PC (PC A) and there is no error messages popup.
    please help me out in this regard.
    Thanks Tanveer

    Hi,
    Firstly, we need to identify is this file sharing or netowrking problem. If you can access to the shared folder and modify its files which locate at PC B through PC A, it indicates file sharing works with no problem.
    After that, we need to check if its networking or software itself problem when reading the .mdb file.
    Put the .mdb file at PC A, then using the software open it for test. If no problem, we need to use Process Monitor to capture the access trace of the software process, we should be able to find some clues.
    You can access to the link below to download Process Monitor:

  • Two PCs connected via TC can't seem to communicate w/ each other

    I have two PCs running XP pro connected to a TC. The TC is also connected to a cable modem. Each PC has successfully obtained an IP address (10.0.1.2, 10.0.1.3). Each can retrieve web pages from the internet. However, they don't seem to be able to communicate with each other. I have re-run my network setup wizard on both PCs and created a home workgroup. When I try use My Network Places ... Home, I only see the local PC. If I ping the other address, the ping times out. I can ping the TC (10.0.1.1) however.
    Any ideas as to why the two computers would not be able to communicate w/ each other but can communicate w/ the internet?

    I just spoke with Apple Care. The support rep did some research and believes the problem is with settings on my computers. This network was working with a different router (and different private network addresses) before I swapped it out for the Time Capsule.
    Anyone have any ideas what might be blocking network replies (or incoming packets) on the various XP computers?

  • VTP between two routers

    PC1 ----- SW1 ------ R1------SERIAL------R2------SW2------PC2
    My SW1 VTP domain and i created 2 VLANs on it. Then on R1 i created sub interface for VLANs
    vlan1 0/0.10 192.168.10.1
    vlan2 0/0.20 192.168.20.1
    I want to do my sw2 client of sw1 domain. How can i do it ?

    You can't really and there would be no point if you have subinterfaces on the router because the IP subnets used for each vlan would be different in each site.
    If you wanted to extend the vlans across the serial link you could look at L2TPv3 to do that and then have the same vlans/IP subnets in each site but even then with two switches I would just use VTP transparent and create the vlans on each switch.

  • How do I extend my network with two routers?

    Hey all,
    I've been wondering for a while how I could solve the weak signals that I get in the lower level of my house from my standard Verizon FiOs router. I have an Airport Extreme still lying around after it was taken out and replaced by the Verizon guys when they installed FiOs and I thought I might be able to put it to use downstairs. Is there any way I could put my Verizon router (which is directly connected to the fiber optic modem) and my Airport Extreme together to work in an extended network so that I could have strong signals in both levels of my house? Is it even possible? Any helps on this issue would be greatly appreciated.

    I'm a bit confused about the terms 'network throughput'. Is that referring to the speed of the network? Your internet speed is slowed down when connecting to a remote station?
    Yes. At least with an 802.11b or g network, the effective network bandwidth is halved with each remote base station in a WDS configuration. In other words, if the maximum theoretical throughput of an 802.11g system is 54 Mbps, adding a remote base station will reduce it to 27 Mbps.
    {quote:title=from Wikipedia:}{quote}
    Two disadvantages to using WDS are:
    • The maximum wireless effective throughput is halved after the first retransmission (hop) that is made. For example, in the case of two routers connected via WDS, and communication is made between a computer that is plugged into router A and a laptop that is connected wirelessly using router B's access point, the throughput is halved, because router B has to retransmit the information during the communication of the two sides. However, in the case of communications between a computer that is plugged into router A and a computer that is plugged into router B, the throughput is not halved since there is no need to retransmit the information.
    • Dynamically assigned and rotated encryption keys are usually not supported in a WDS connection. ...
    I didn't really believe it until I added a remote base station and checked my network speed with http://www.speakeasy.net/speedtest/, with and without WDS.
    As I understand it, 802.11n networks are not be affected in the same manner due to its ability to handle multiple data streams simultaneously.
    If you want to extend your network without sacrificing bandwidth, you can certainly connect the base station Ethernet ports. That is not WDS; Apple calls it "extending a network". That's also how they do it in Apple's retail stores (at least when they used b/g AEBSs).

  • Setting up back-to-back async connection between 2 routers

    Hi,
    I am trying to setup a back-to-back async connection between 2 routers via the async serial interface. The connection between the two routers are via a smart serial to RS232 male(CAB-SS-232MT) cable connecting to another RS232 female to smart serial (CAB-SS-232FC) cable. What I am trying to do is to push the async data from one router (Router A) to another router (Router B).
    When I try to capture the async data from the async serial interface on the source router (Router A) while disconnecting the back-to-back connection from Router B, it is showing the correct data. The data capture is via the smart serial to RS232 male cable connecting to Router A, to a PC via hyperterminal. But however, when the back-to-back connection is connected and I try to do a reverse telnet at Router B opening up the port for the async interface on Router B, it seems to be showing incorrect data. I have confirmed that the speed and configurations on both routers are matched.
    Does it require to have two physical async modems in between both routers for signalling? Any experts who are familiar with such setups can advise on why the async data at Router B appear as incorrect with unreadable characters? Any help is greatly appreciated.

    Hey Sebastian,
    Had the same issue, which I just managed to get it resolved.
    When you insert the modem, the router will create an Async interface for it lets say Async 0/1/0
    then all what you've to do is:
    chat-script DialOut ABORT ERROR ABORT BUSY "" "AT" OK "ATDT \T" TIMEOUT 45 CONNECT \c
    line 0/1/0
    exec-timeout 0 0
    script dialer DialOut
    modem InOut
    transport preferred none
    transport input all
    transport output all
    stopbits 1
    speed 115200
    flowcontrol hardware
    and to dial a the remote router all what's required is:
    reverse telnet to the above line (show line to know the line number) then type atdt
    Let me know in case you still get issues

  • Ways to connect two routers

    Hello,
    We have two routers connected as shown in the diagram:
    We would like to create a one-hop connection ("peering") between the two routers (over the link shown) for routing purposes (iBGP, OSPF, static routes).
    What are the suggested way(s) to do it?
    Method 1: We have tried creating two GRE tunnels (one for IPv4 and one for IPv6) and it works but we are having various issues (which we are still troubleshooting)
    Method 2: We could create IPSec tunnels; I have not tried it.
    Method 3: This is my main question here. Can we define a common VLAN on the two routers so that, by using trunk links in-between, the two interfaces (actually a new subinterface of each: R1,G0/0.x - R2,G0/1.x) can coexist "alone" on one VLAN?
    Other suggested methods please?
    Thanks in advance for your assistance.
    Regards,
    Nick

    Thanks for the reply.
    Here is the current setup:
    {View image and zoom in to full scale for clearer reading!}
    With this configuration, the tunnels seem to be working correctly, however we are still having a problem: When I switch traffic so that it uses the tunnels, netflow export from R1 to a netflow server (using nfdump/nfsen) which is located at a LAN connected to R2, is not recorded correctly; I see (on R1):
    # sh ip flow export
    Flow export v9 is enabled for main cache
    Export source and destination details :
    VRF ID : Default
    Source(1) 195.251.xxx.yyy (Loopback0)
    Destination(1) 195.251.xxx.xxx (9995)
    Version 9 flow records
    680074 flows exported in 8490 udp datagrams
    0 flows failed due to lack of export packet
    1579 export packets were sent up to process level
    0 export packets were dropped due to no fib
    0 export packets were dropped due to adjacency issues
    0 export packets were dropped due to fragmentation failures
    0 export packets were dropped due to encapsulation fixup failures
    and I find that our traffic is not recorded correctly. (When we don't use these tunnels -but another route not shown in the diagram, which does not involve tunnels- then "export packets sent up to process level" are 0 and netflow export works correctly.)
    Netflow monitoring is critical to our network, so we have to troubleshoot this, before we can use this configuration in production. (I am thinking of opening a new thread for this problem.)
    Any and all suggestions will be welcome.

  • Help picking between 2 routers

    So I'm between two routers. I plan on flashing the router with dd-wrt immediately. Just want some advise please.
    Between
    Netgear R7000 Nighthawk AC1900 Smart WiFi Router ‑ 4‑Port Switch
    And the
    ASUS RT‑AC87U Wireless router ‑ 4‑port switch ac2400
    The asus one is the newer one with better hardware, but I'm not sure which will work out better for me in the long run.
    My current situation: house with three floors, 6 regular users, and roughly 7-10 devices concurrently.
    Right now I have a 57 Mbps connection using a net gear router with ddwrt.
    One issue I'm currently running into is every so often the wifi only will crash while the wired connection stays live.  I've tried trouble shooting for past several months No resolution. I am considering a speed upgrade soon, but not until I can sustain a stable connection with the current setup.
    Most common use is gaming and streaming via Netflix, along with general browsing.
    What I'm looking for is stable hardware that will keep me future proof for a bit longer, that is why im erring towards the asus since it is the new hardware, but they are also the less tested company in terms of routers.
    I'll appearciate any advise.
    Currently. Can get asus for $258, and netgear for $171
    I am hoping to upgrade to a 500 Mbps connection down the road.

    Thank you for your help, re-instating the DHCP did the trick (after a power cycle).
    Just in case anyone else needs to do this, here is my final config;
    WAG160N is set to 192.168.1.1 with DHCP enabled.
    BEFW11S4 is set to 192.168.2.1 with DHCP enabled and auto select IP address.
    Thanks for all the suggestions everyone - just need a Wireless N ADSL router (to replace the two I've got hooked up) that can log all internet traffic now
