Boitsebiso ka VRRP Interface Tracking

Virtual Router Redundancy Protocol (VRRP) ke protocol ea LAN-side e fanang ka litšebeletso tse sa hlokahaleng tsa liheke bakeng sa li-switches le liteishene tse ling tsa IP. Ho Cisco SD-WAN, o ka hlophisa VRRP ho li-interfaces le li-subinterfaces, ka har'a VPN.
Ho fumana lintlha tse ling, sheba Configuring VRRP.
Karolo ea VRRP Tracking e thusa ho fetohela ho backup kapa router ea bobeli ea VRRP maemong a latelang:
- Haeba kotopo e le 'ngoe (kapa lithanele tse peli - ha u lokisa ho fokotsa mosebetsi u sebelisa Transport Locators (TLOC)) mochine oa vEdge o theoha. Tabeng ena, VRRP ea bohlokoa e fokotseha 'me router ea bobeli e fetoha router ea mantlha. VRRP e tsebisa phetoho ena ho koanela ka ho Overlay Management Protocol (OMP).
- VRRP e ka latella ntho e le 'ngoe kapa ntho e Sireletsehileng ea Khokahano ea Marang-rang (SIG) bakeng sa sehlopha. Sebopeho sa sebopeho se ka ba le li-interfaces tse 'nè. Kahoo, sehlopha se ka tseba ho latela lithanele tse fihlang ho tse 'ne. Taba ea mantlha ea VRRP e fokotseha ha feela lihokelo tsohle tsa sebopeho sa sebopeho li theoha.

Lithibelo le Meeli

VRRP e tšehetsoa feela ka li-VPN tse lehlakoreng la litšebeletso. Haeba u sebelisa li-subinterfaces, lokisa likhokahano tsa 'mele tsa VRRP ho VPN 0.
Ts'ebetso ea VRRP e nolofalitsoe ho sebopeho sa uplink sa 'mele kapa sebopeho se hlakileng sa kotopo (IPSEC kapa GRE kapa ka bobeli).
Karolo ea VRRP Tracking ha e tšehetse sehlohlolo sa IP joalo ka ntho.
U ka lekola boholo ba li-interfaces tse 'ne ka nako e le ngoe u sebelisa tracker e le' ngoe. Phetoho ea boemo ba VRRP e qala ha feela likhokahano tse 'ne li theoha.

U ka sebelisa tracker e tšoanang tlas'a lihlopha tse ngata tsa VRRP kapa li-VPN.
Ha o khone ho hlophisa tloc-change le ho eketsa khetho ho lihlopha tse fetang bonngoe tsa VRRP.
Ho Cisco SD-WAN tokollo 20.6.1 le litokollo tsa pejana, o ka lokisa VRRP tracking feela ka template ea Cisco vManage CLI.
Hlokomela
- Ho qala ka Cisco SD-WAN tokollo 20.7.1, o ka lokisa VRRP latedisa o sebelisa Cisco vManage tšobotsi template hammoho.

VRRP Tracking Sebelisa Maemo

Boemo ba VRRP bo khethoa ho ipapisitsoe le boemo ba khokahano ea kotopo. Haeba kotopo kapa sebopeho se theohile ho VRRP ea mantlha, joale sephethephethe se lebisitsoe ho VRRP ea bobeli. Routa ea bobeli ea VRRP karolong ea LAN e fetoha VRRP ea mantlha ho fana ka monyako bakeng sa sephethephethe se lehlakoreng la litšebeletso.

Zscaler Tunnel Sebelisa Case 1-Primary VRRP, Mofani a le Mong oa Inthanete
Litsela tsa mantlha le tsa bobeli tsa Zscaler li hokahantsoe ka mofani a le mong oa inthanete ho VRRP ea mantlha. Li-routers tsa mantlha le tsa bobeli tsa VRRP li hokahantsoe ka ho sebelisa katoloso ea TLOC. Boemong bona, phetoho ea boemo ba VRRP e etsahala haeba lithanele tsa mantlha le tsa bobeli li theohela ho VRRP ea mantlha. Boleng bo reriloeng esale pele bo fokotseha ha ntho e lateloang e theoha, e leng se bakang phetoho ea boemo ba VRRP. Ho qoba mokhoa oa asymmetric, VRRP e tsebisa phetoho ena ho Overlay ka OMP.

Zscaler Tunnel Use Case 2-VRRP Routers in TLOC Extension, Dual Internet Providers
Li-routers tsa mantlha le tsa bobeli tsa VRRP li lokiselitsoe ka mokhoa oa ho fumaneha o phahameng oa TLOC. Litsela tsa mantlha le tsa bobeli tsa Zscaler li hokahane ka kotloloho le li-routers tsa mantlha le tsa bobeli tsa VRRP, ka ho latellana, li sebelisa bafani ba marang-rang ba babeli. Boemong bona hape, phetoho ea boemo ba VRRP e etsahala haeba lithanele tsa mantlha le tsa bobeli li theohela ho VRRP ea mantlha. Boleng bo reriloeng esale pele bo fokotseha ha ntho e lateloang e theoha, e leng se bakang phetoho ea boemo ba VRRP. VRRP e tsebisa phetoho ena ho Overlay ka OMP.

Khetho ea TLOC
