IPv6 Generic Prefix
IPv6 generic prefix feature ua kom yooj yim network renumbering thiab tso cai rau automated prefix txhais. IPv6 generic (los yog general) prefix (rau example, /48) tuav ib tug luv luv prefix, raws li tus naj npawb ntawm ntev, ntau-specific prefixes (rau example, /64) txhais tau. Thaum cov lus qhia ua ntej hloov pauv, tag nrho cov lus qhia tshwj xeeb ua ntej raws li nws yuav hloov, ib yam nkaus.

Cov ntaub ntawv hais txog IPv6 Generic Prefix
IPv6 General Prefixes
Sab saum toj 64 khoom ntawm qhov chaw nyob IPv6 yog tsim los ntawm lub ntiaj teb routing prefix ntxiv rau subnet ID, raws li tau hais tseg hauv RFC 3513. Ib lub npe ua ntej (rau example, /48) tuav ib tug luv luv prefix, raws li tus naj npawb ntawm ntev, ntau-specific prefixes (rau example, /64) txhais tau. Thaum cov lus qhia ua ntej hloov pauv, tag nrho cov lus qhia tshwj xeeb ua ntej raws li nws yuav hloov, ib yam nkaus. Qhov kev ua haujlwm no ua kom yooj yim heev rau kev hloov pauv hauv lub network thiab tso cai rau kev siv lub npe ua ntej txhais.For example, ib tug general prefix tej zaum yuav 48 ntsis ntev ("/48") thiab qhov tshwj xeeb prefixes generated los ntawm nws tej zaum yuav 64 ntsis ntev ("/64"). Hauv qab no example, qhov seem ntawm 48 cov khoom ntawm tag nrho cov prefixs tshwj xeeb yuav zoo ib yam, thiab lawv yog tib yam li cov lus ua ntej nws tus kheej. Tom ntej no 16 ntsis yog txhua yam sib txawv.
- General prefix: 2001:DB8:2222::/48
- Specific prefix: 2001:DB8:2222:0000::/64
- Specific prefix: 2001:DB8:2222:0001::/64
- Specific prefix: 2001:DB8:2222:4321::/64
- Specific prefix: 2001:DB8:2222:7744::/64
General prefixes tuaj yeem txhais tau ntau txoj hauv kev
- Kev tuav tes
- Raws li 6to4 interface
- Dynamically, los ntawm cov lus ua ntej tau txais los ntawm Dynamic Host Configuration Protocol (DHCP) rau IPv6 prefix delegation tus neeg siv khoom
Ntau qhov tshwj xeeb ua ntej, raws li cov lus qhia dav dav, tuaj yeem siv thaum teeb tsa IPv6 ntawm qhov sib txuas.

Txhais lub npe ua ntej rau qhov chaw nyob IPv6.
Thaum txhais cov lus hais ua ntej raws li 6to4 interface, qhia qhov 6 rau 4 keyword thiab interface-type interface-number sib cav. Thaum txhais cov lus qhia dav dav raws li qhov kev sib txuas siv rau 6to4 tunneling, cov lus qhia dav dav yuav yog ntawm daim ntawv 2001: abcd:: / 48, qhov "abcd" yog IPv4 chaw nyob ntawm lub interface hais txog. |
