Ukuqonda ekusebenzeni: I-DMVPN kanye ne-Per-Tunnel QoS

Ngaphambi kokuqala kwesifundo "Unjiniyela Wenethiwekhi" Sikulungiselele ukuhunyushwa kwezinto ezithokozisayo

Kunento eyodwa enhle nge-DMVPN engihlangane nayo esikhathini esidlule: I-DMVPN Per-Tunnel QoS. Ngokusobala akumina ngedwa (njengegundane laselabhu) ocabanga ukuthi lokhu kuhle. Ngaso sonke isikhathi uma ngibonisa lokhu kubantu, ngibona amehlo abo ekhanya njengoba izibani ezincane ziqala ukukhanya emakhanda abo zikhombisa imibono lapho abangazisebenzisa khona.

Isikhathi sokukhipha i-geek yakho!

Ake senze sengathi Igatsha_1 и Igatsha_2 zisemhubheni ofanayo we-DMVPN onehabhu le-DMVPN "Foxtrot14". Sithanda ukusebenzisa inqubomgomo ye-QoS kusuka kuhhabhu ukuya kwesinye Igatsha_2, kodwa hhayi ngenxa Igatsha_1. Njengoba zisemhubheni ofanayo we-mGRE, sikwenza kanjani lokhu?

Empeleni okufanele sikwenze:

• Kuhabhu ye-DMVPN:
  1. Silungiselela esigabeni sokucushwa komhlaba wonke izinqubomgomo ze-QoS ofuna ukuthi ihabhu "inikeze" njengezinqubomgomo ze-QoS zama-spoks.
  2. Sisebenzisa zonke izinqubomgomo "ozozinikeza" kuma-spocks kusixhumanisi esibonakalayo se-DMVPN sisebenzisa umyalo. Iqembu lemephu ye-ip nhrp
• Ku-spock ye-DMVPN, lungiselela isixhumi esibonakalayo se-DMVPN negama leqembu elifakwe imephu ongathanda ukulisebenzisa kulo.

Kuhabhu ye-DMVPN

Ake sikuthole:

“1) Lungiselela esigabeni sokucushwa komhlaba wonke izinqubomgomo ze-QoS ofuna ukuthi ihabhu “lizinikeze” njengezinqubomgomo ze-QoS zama-spoks”

Ngakho-ke lokho ongakubona ngenhla ukuthi silungiselela ihabhu lethu le-DMVPN ngeminikelo emi-5 ehlukene ye-spokam QoS.

1. 1.5Mbps
2. 2Mbps
3. 5Mbps
4. 10Mbps
5. Awukho umkhawulo

“2) Sisebenzisa zonke izinqubomgomo “ozozinikeza” kuma-spocks kusixhumi esibonakalayo somhubhe we-DMVPN sisebenzisa umyalo weqembu lemephu ye-ip nhrp”

Ku-DMVPN Spock

"Ku-spock ye-DMVPN, lungiselela isixhumi esibonakalayo se-DMVPN negama leqembu elifakwe imephu ongathanda ukulisebenzisa kulo."

Ngakho ngizovele ngiqhubekele phambili I-Echo3 (Branch_2) futhi ubeke umyalo “ip nhrp group spoke-2Mbps” kusixhumi esibonakalayo sikamhubhe we-Spock.

Kuzokwenzekani manje? I-Echo3 imane ibeke igama elithi “spoke-2Mbps” esicelweni sokubhalisa se-NHRP. Voila! Kulula kanjalo. Kuhle, akunjalo? Uma udinga ukuvuselela kancane ekubhaliseni i-NHRP, funda Ukuzijabulisa Kulebhu: I-Sniffer Ilandela Ukuqala Komhubhe we-DMVPN. Lapho uzothola izisekelo zokucela ukubhaliswa kwe-NHRP.

Ake sibone ukuthi ibukeka kanjani kunethiwekhi nakuhabhu ye-DMVPN.

Ungathola ifayela lamanje pcapesizoyicabangela ndawonye

dmvpn_tunnel_startup_per_tunnel_QoS.pcap < - Iku-Dropbox yami yomphakathi futhi ngihlela ukuyigcina lapho iminyaka embalwa.

Silungile?

Sizobheka Uhlaka 18 kanye Nohlaka 21 ngokuphathelene namanethiwekhi alandelayo namakheli e-IP. Beka lokhu eduze kwe-sniffer trace ukuze ukwazi ukufanisa kangcono namakheli e-IP.

Ngakho eyokuqala ifreyimu 18. Isicelo sokubhaliswa kwe-NHRP kusuka I-Echo3 (Branch_2) kubukeka kujwayelekile ngokuphelele size sifike ku-NHRP Vendor Private Extension.

Ingabe ufuna ukuzitika ngobuqili kuwe?

Kwenzekani ngemuva kokuthi Uhlaka 18 lushaye ihabhu le-DMVPN I-Foxtrot14? Ngoba I-Echo3 (Branch_2) ifuna ukuthi "spoke-2Mbps" isetshenziswe kuyo akusho ukuthi lena inketho emisiwe kuhabhu. Ngakho-ke uzobona uhlaka 21 njengempendulo ekwazisweni kokubhalisa eqinisekisa "i-spoke-2Mbps" esigabeni somthengisi.

Manje?

Asiqhubekele phambili I-Foxtrot14 futhi ake sibone ukuthi ucabangani ngalesi simo.

Kuyamangalisa! Emhubheni ofanayo we-mGRE sine-QoS efakwe kuhabhu yokukhuluma ithrafikhi kuyo igatsha_2, kodwa hhayi igatsha_1.

*QAPHELA: Lokhu okuthunyelwe kwashicilelwa okokuqala kule sayithi ngo-2015. Igcine ukubuyekezwa futhi yafomethwa ngoFebhuwari 15, 2020.
