Kunzwisisa mukuita: DMVPN uye Per-Tunnel QoS

Kusati kwatanga kosi Network Engineer akakugadzirira shanduro yezvinyorwa zvinonakidza

Pane chinhu chimwe chikuru nezveDMVPN chandakawana imwe nguva yapfuura: DMVPN Per-Tunnel QoS. Zviripachena, handisi ndega (segonzo rerabhoritari) anofunga kuti izvi zvakanaka. Pese pandinoratidza izvi kuvanhu, ndinoona maziso avo achipenya semhedzisiro yezviedza zvidiki zvinotanga kupenya mumisoro yavo, zvichiratidza kuti pfungwa dzinouya kwavanogona kuishandisa.

Inguva yekusunungura geek yako!

Ngatiedzei kuti Bazi_1 и Bazi_2 vari mune imwecheteyo DMVPN mugero neiyo DMVPN hub "Foxtrot14". Tinoda kushandisa mutemo weQoS kubva kuhub kuenda kune spock Bazi_2asi kwete nokuda Bazi_1. Sezvo vari muGRE mugero mumwechete, tinoita sei izvi?

Chaizvoizvo zvatinofanira kuita ndezvekuti:

• PaDMVPN hub:
  1. Isu tinogadzirisa muchikamu chekugadzirisa chepasi rose marongero akasiyana eQoS aunoda kuti hubhu "ipe" seQoS marongero ezvipokisi.
  2. Isu tinoshandisa ese marongero auri "kupa" kune spocks muDMVPN tunnel interface uchishandisa rairo. ip nhrp mepu boka
• PaDMVPN, tinogadzirisa iyo DMVPN interface ine zita reboka rine mepu raungade kushandisa kwariri.

PaDMVPN hub

Ngatizvinzwisisei:

"1) Gadzirisa muchikamu chegadziriro yepasi rose mitemo yakasiyana-siyana yeQoS yaunoda kuti hubhu "ipe" seQoS mitemo yezvipoko

Saka, kazhinji, zvaunogona kuona pamusoro ndezvokuti tiri kugadzirisa DMVPN hub yedu ine 5 yakasiyana QoS inopa kune Spokes.

1. 1.5Mbps
2. 2Mbps
3. 5Mbps
4. 10Mbps
5. Hapana muganhu

"2) Shandisa mitemo yose yauri "kupa" kune spocks muDMVPN tunnel interface uchishandisa ip nhrp mepu yeboka rekuraira"

PaDMVPN Yakataura

"Pane DMVPN spock, gadzirisa iyo DMVPN interface ine zita reboka rine mepu raungade kuisa kwariri."

Saka ndinoenda chete Echo3 (Bazi_2) uye isa murayiro “ip nhrp group spoke-2Mbps” kune Spock's tunnel interface.

Chii chichaitika zvino? echo3 inongoisa zita rekuti "spoke-2Mbps" muchikumbiro chekunyoresa cheNHRP. Voila! Zviri chaizvo kuti nyore. Neat, huh? Kana iwe uchida kuzorodza zvishoma pakunyoresa kweNHRP, verenga Kunakidzwa muLab: Sniffer Kutsvaga DMVPN Tunnel Kutanga. Ikoko iwe unowana izvo zvekutanga zvechikumbiro chekunyoresa cheNHRP.

Ngatione kuti inotaridzika sei pane network uye paDMVPN hub.

Iwe unogona kuwana ikozvino faira pcap, zvatichakurukura pamwe chete

dmvpn_tunnel_startup_per_tunnel_QoS.pcap <- Iri muDropbox yangu yeruzhinji uye ndinoronga kuichengeta ikoko kwemakore mashoma.

Kugadzirira?

Isu tichatarisa Frame 18 uye Frame 21 maererano neanotevera network uye IP kero. Isa izvi padhuze neiyo sniffer trace kuti iwe ugone kuenzanisa maIPs zvirinani.

Saka yekutanga ifuremu 18. NHRP chikumbiro chekunyoresa kubva Echo3 (Bazi_2) inotaridzika zvakanaka kusvika tasvika kuNHRP Vendor Private Extension.

Unoda kupuruzira geek mukati mako?

Chii chinoitika mushure mekunge Frame 18 yarova iyo DMVPN hub Foxtrot14? Nokuti Echo3 (Bazi_2) inoda kuti "spoke-2Mbps" ishandiswe kwairi, hazvireve kuti iyi isarudzo yakagadziriswa pane hubhu. Saka iwe uchaona furemu 21 zvakare semhinduro kuchikumbiro chekunyoresa ichisimbisa "yakataura-2Mbps" muchikamu chemutengesi.

Zvino chii?

Handei ku Foxtrot14 uye ona zvaanofunga nezvenyaya iyi.

Zvinoshamisa! Mune imwechete mGRE mugero isu tine QoS yakaiswa kune hub kuti spock traffic kune bazi_2asi kwete bazi_1.

* CHERECHEDZA: Ichi chinyorwa chakatanga kuburitswa pane ino saiti muna 2015. Yakapedzisira kuvandudzwa uye kufomatidzwa muna Kukadzi 15, 2020.
