Timer Lub sijhawm
Cov no yog cov nqi ntawm cov OSPF timers : Nyob zoo - Lub sijhawm lub sijhawm hauv vib nas this uas lub router xa ib qho OSPF nyob zoo pob ntawv. Nyob rau hauv kev tshaj tawm thiab point-to-point txuas, lub ua ntej yog 10 seconds. Tuag -Lub sij hawm hauv vib nas this tos ua ntej tshaj tawm ib tus neeg nyob ze tuag.
Kev sib raug zoo, nyob zoo thiab lub sijhawm tuag hauv OSPF yog dab tsi?
OSPF Nyob Zoo Thiab Lub Sijhawm Tuag . OSPF siv nyob zoo pob ntawv thiab ob sijhawm txhawm rau xyuas seb tus neeg nyob sib ze tseem muaj sia nyob lossis tsis: Nyob zoo lub sijhawm : qhov no txhais tau tias peb xa ntau npaum li cas nyob zoo pob ntawv. Tuag ncua : qhov no txhais tau tias peb yuav tsum tos ntev npaum li cas nyob zoo pob ntawv ua ntej peb tshaj tawm cov neeg nyob ze tuag.
Tom qab, lo lus nug yog, dab tsi yog timers ntawm OSPF? Nyob zoo sijhawm yog cov lub sijhawm uas cov txheej txheem routing xa cov pob ntawv nyob zoo rau nws cov neeg nyob ze txuas ncaj qha nrog TTL ntawm 1 thiab cov neeg tuag sijhawm yog cov lub sijhawm ntawm lub router yuav tshaj tawm cov neeg nyob ze yog tias nyob zoo cov pob ntawv tsis tau txais los ntawm cov neeg nyob ze nyob rau lub sijhawm teev los ntawm cov neeg tuag- lub sijhawm.
Ib yam li ntawd, koj tuaj yeem nug, Kuv yuav teeb tsa lub sijhawm nyob zoo li cas hauv OSPF?
Txhawm rau teeb tsa qhov nyob zoo thiab lub sijhawm tuag:
- Tsim ib cheeb tsam OSPF. Nco tseg.
- Qhia cov interfaces. [hloov raws tu qauv ospf cheeb tsam 0.0.0.0]
- Configure lub caij nyob zoo. [kho cov kev cai ospf cheeb tsam 0.0.0.0]
- Configure lub sij hawm tuag.
- Yog tias koj ua tiav kev teeb tsa lub cuab yeej, ua qhov kev teeb tsa.
Qhov twg ospfv2 cov lus txib ua rau koj tuaj yeem txheeb xyuas qhov nyob zoo lub sijhawm thiab lub sijhawm tuag?
Siv cov yeeb yam ip ospf interface lus txib rau txheeb xyuas tus lub sijhawm tuag thiab nyob zoo lub sijhawm.
