Best Practice for Redundant Local Area Network

  • @xteam super thank you for the very clear explanation. will tell my boss about this setup. thank you po!

    (grabe nakakahiya nagpapa consulta ako ng walang bayad haha)
  • Thanks sirs.. New learning again.. :)
    More more more..

    I\'ll just charge my other clients more to cover yours...
  • hi ulit!

    my boss is kind of a d*ck. gusto nya eh yung mga workstations sa branch ang magpapalit ng gateway. let\'s say hindi nawala yung leased line connection hindi na nya (meaning yung mga pc sa branch) makita si 192.168.1.2 (router ng main office). ang gusto ng boss ko mangyari ay magpapalit ng gateway to 192.168.1.3 (router ng branch) and if mag resume connection ay babalik to 192.168.1.2. Is this possible? meron ba ganitong application sa windows?

    complex daw yung gagalawin pa yung mga router/firewall at natatakot sya. hindi rin sure sa compatibility if yung mga ginagamit at gagamitin eh compatible ang VRRP.

    sorry, kahit ako i dont agree with this set up pero yun gusto nya mangyari.

  • oops we tested using alternate configuration with multiple gateways sa tcp/ip settings. it worked, perong ibang subnet na lang imbes na pareho.
  • and if mag resume connection ay babalik to 192.168.1.2. Is this possible? meron ba ganitong application sa windows


    not sure kung revertive ang gateway selection sa windows. meaning, pag nag fail yung primary, sa secondary pupunta. pero kung nag balik ang primary, mag stay lang sya sa secondary until mag fail ito at pupunta sa primary
  • ^ noted sir... tigil muna ako ng research now. bahala na muna yung boss ko at yung senior ko hehe..
  • Parang sa windows merong metric thing sa gateway. Not sure, di ako naka windows ngayon. Pero e prioritize nya ang lower metric. You can input multiple gateway ip.

    Pero mukhang lumang style na yan. Vrrp is better siguro. Yung mga routers ngayon at o.s. Ay going into this.

    Example, untangle may new feature na ng vrrp. Centos pwede na rin vrrp.

    Im sure sa mga high end equipment meron nyan.
  • our boss and a senior tested using different networks (pc was configured to have multiple gateways) and when a we connect a lan cable to the pc and then tested with another, it works naman. but we havent replicated the scenario in which if two networks are active and say network A (the preferred gw) went down and the PC uses GW B, and then GW A goes up again, the PC should connect back to A. Im having doubts, but we will see.

    by the way, ang gagaling po ninyo. nagsisimula pa lang ako sa networking field (actually IT ang job ko ngayon) and would like to excel in this field katulad nyo. thanks for all the input mga master!
  • Cisco ba lahat ng equipments? Baka pwede GLBP para may high availability ka na, load-balancing pa. Compared sa HSRP and VRRP maiiwan yung isa as tenga. sayang bandwidth. I could be wrong, d ko masaydo binasa mga post. :)

    WALA BA MGA NETWORK ENGINEER GROUP DITO? GUSTO KO NG MGA TAONG NAKAKAUSAP TUNGKOL SA NETWORKING, DAMI AKO TANONG AND GUSTO I-TEST. Minsan d sapat ang GNS3 simulation, nakakapraning pag may nalilimutan ka na lines.
  • nabasa ko na ibang post. Possible auto switch yan, kung cisco equipments nyo I suggest mag GLBP ka para mas sulit. Pag hindi cisco VRRP nalang nga. Configure Preempt and delay timers, fine tune mo lang VRRP ok na yang setup. for the meantime kahit siguro default VRRP wlang fine tuning pwede na for now. maachieve lang yang gusto ng boss mo. Isa lang magiging gateway nyo dyan kaya wala na gagalawin sa user side. virtual gateway yan.
  • ^ noted sir.. thanks for the input. gusto for now ng boss ko eh yung workstation lang sa new branch ang gagalawin at hindi yung mga router. he has his own reasons that even i don\'t agree. we are looking into adding secondary gateways sa mga pc sa branch. we havent thoroughly tested it.

    walang routing and remote access ang workstation OS, best bet mo ay dual wan router, or the cheaper mikrotik then yun meron yung routing, pag nag down yung isa mag switch sya sa isa pang connection. pwede mo rin gamitin yung backup pero walang automatic switch
  • Hello Mga ka-TPC Network Maasters,

    Anyone po na gumagamit ng Cacti Monitoring Tool?
    may question lang po ako about reporting.
    sana may sumagot..
    ilang lingo na po ako umiiyak.

    Thanks,
    Baguhan
  • pa help nman po.

    ano po pang test ng network speed and connection simula sa router-hub-pc?

    kc yung network ko sa room, laging lag ang connection browsing and gaming about 30 seconds delay. kapag nag speed test nmn me ok nman daw ang lumalabas. pero na experience ko kapag ginagamit ko na may lag.
