OSPFv2 stands rau Qhib Shortest Path Thawj version 2 thiab OSPFv3 stands rau Qhib Shortest Path Thawj version 3. OSPFv2 yog IPv4's OSPF version, whereas OSPFv3 yog IPv6's OSPF version. Hauv OSPFv2 , ntau OSPF piv txwv rau ib lub interface tsis txaus siab, whereas nyob rau hauv OSPFv3 , ntau OSPF piv txwv rau ib qho interface tau txais kev txhawb nqa.

Ib yam li ntawd, OSPFv2 yog dab tsi?

OSPFv2 yog IETF txuas-xeev raws tu qauv (saib "Txuas-State Protocols" ntu ntawm nplooj 1-9) rau IPv4 tes hauj lwm. Cov neeg nyob sib ze routers sim tsim qhov chaw nyob ib sab, uas txhais tau hais tias cov routers synchronize lawv cov ntawv txuas-xeev cov ntaub ntawv los xyuas kom meej tias lawv muaj tib yam. OSPFv2 routing cov ntaub ntawv.

IPv4 puas txhawb OSPFv3? OSPFv3 ua tsis yog xwb kev txhawb nqa pauv ntawm IPv6 txoj kev, tab sis nws kuj txhawb nqa pauv ntawm IPv4 txoj kev. Qhov tshiab tshaj plaws OSPFv3 configuration mus kom ze siv ib leeg OSPFv3 txheej txheem. Nws muaj peev xwm txhawb IPv4 thiab IPv6 hauv ib qho OSPFv3 txheej txheem.

Hais txog qhov no, dab tsi yog ob qho kev txhim kho uas OSPFv3 txhawb nqa OSPFv2?

  • Nws tuaj yeem txhawb ntau tus IPv6 subnets ntawm ib qhov txuas.
  • Nws yuav tsum tau siv ARP.
  • Nws taug kev hla kev sib txuas es tsis yog hauv network.
  • Nws txhawb nqa txog li 2 piv txwv ntawm OSPFv3 dhau qhov sib txuas.

Kuv yuav qhib OSPFv2 li cas?

Cov txiaj ntsig ntawm Ua kom OSPFv2 Ntawm qhov Interface Basis Xwb, koj tuaj yeem ua tau pab OSPFv2 meej meej ntawm qhov interface los ntawm kev siv ip ospf cheeb tsam hais kom ua, uas tau nkag rau hauv interface kev teeb tsa hom. Qhov no muaj peev xwm simplifies lub kev teeb tsa ntawm unnumbered interfaces nrog ntau qhov chaw.
