ʻIke Huahana

Hāʻawi ka IP Addressing Configuration Guide i nā kuhikuhi no ka hoʻonohonoho ʻana i nā helu IP ma nā polokalamu Cisco IOS XE 17.x. Hoʻopili ia i ka ʻōlelo IPv4 a me IPv6, a me nā ʻōlelo aʻoaʻo hoʻoponopono a me ka ʻike e pili ana i nā loko IP overlapping address. Ke manaʻo nei ke alakaʻi e kōkua i nā mea hoʻohana e hoʻokumu i ka pilina IP i kahi pūnaewele ma o ka hāʻawi ʻana i nā helu IP i nā pilina.

Nā ʻōlelo hoʻohana huahana

Mokuna 1: Hoʻonohonoho ʻana i nā helu IPv4
Hāʻawi kēia mokuna i ka ʻike e pili ana i nā helu IP, me ka helu binary, ka hoʻonohonoho ʻana i ka helu IP, nā papa helu IP, ka subnetting pūnaewele IP, a me ka hoʻokele ʻana ma waena o ka papa inoa ʻole. E wehewehe pū ana i ka hoʻonohonoho ʻana i nā helu IP a hoʻokumu i ka pilina IP i kahi pūnaewele ma o ka hāʻawi ʻana i kahi IP address i kahi interface.

Mokuna 2: Nā Manaʻo Hoʻoponopono
Hāʻawi kēia mokuna i nā ʻōlelo aʻoaʻo hoʻoponopono no ka hoʻonui ʻana i ka helu o nā host IP i kākoʻo ʻia ma kahi pūnaewele me ka hoʻohana ʻana i nā helu IP lua. Hoʻopili pū ia i nā loko IP overlapping address, me nā palena, nā pōmaikaʻi, a me ka hoʻonohonoho examples.

Mokuna 3: Pehea e hana ai nā Pūʻulu IP Address
Hōʻike kēia mokuna i ka hana ʻana o nā pools IP overlapping address a hāʻawi i nā ʻōlelo aʻoaʻo no ka hoʻonohonoho ʻana a me ka hōʻoia ʻana i kahi pūʻulu wai kūloko. Loaʻa iā ia ka hoʻonohonoho examples a me nā kuhikuhi hou aʻe no ka hoʻonohonoho ʻana i nā pool address overlapping IP.

Mokuna 4: Auto-IP
Hoʻopili kēia mokuna i Auto-IP, me nā koi mua, nā kapu, a me ka ʻike e pili ana i Auto-IP. Hāʻawi ia i kahi overview ʻO Auto-IP, wehewehe i ka manaʻo o ka mīkini hua, a hāʻawi i nā ʻōlelo kuhikuhi no ka hoʻonohonoho ʻana i ka Auto-IP a me ka hoʻoponopono ʻana i nā paio me ka hoʻohana ʻana i ka ʻenehana Auto-Swap.

Mokuna 5: Ka hoʻonohonoho ʻana i kahi mea hua
Ke nānā nei kēia mokuna i ka hoʻonohonoho ʻana i kahi mea hua no ka hana Auto-IP. Hāʻawi pū ia i nā ʻōlelo aʻoaʻo no ka hoʻonohonoho ʻana i ka hana Auto-IP ma nā ʻaoʻao node no ka hoʻokomo ʻana i kahi apo IP-Auto. Hoʻonohonoho examples a me nā kuhikuhi hou aʻe.

Mokuna 6: ʻŌlelo IPv6
Kūkākūkā kēia mokuna i ka ʻōlelo IPv6 a me ka pilina kumu. Hoʻopili ia i nā mea kapu, nā ʻano leka uila IPv6, ka hōʻike ʻana o ka helu helu IPv6, ka poʻomanaʻo packet IPv6 maʻalahi, DNS no IPv6, Cisco
Kākoʻo ʻo Discovery Protocol IPv6 address, IPv6 prefix aggregation, IPv6 site multihoming, IPv6 loulou ʻikepili, a me ʻelua IPv4 a me IPv6 pūʻulu protocol. Hāʻawi pū ia i nā ʻōlelo kuhikuhi no ka hoʻonohonoho ʻana i ka leka uila IPv6 a me ka pilina kumu.

Nīnau: He aha ke kumu o kēia alakaʻi?
A: ʻO ke kumu o kēia alakaʻi ka hāʻawi ʻana i nā kuhikuhi no ka hoʻonohonoho ʻana i nā helu IP ma nā polokalamu Cisco IOS XE 17.x a me ka hoʻokumu ʻana i ka pilina IP i kahi pūnaewele.

Nīnau: Ua uhi anei kēia alakaʻi i ka ʻōlelo IPv4 a me IPv6?
A: ʻAe, uhi kēia alakaʻi i ka helu IPv4 a me IPv6.

Nīnau: Aia kekahi mau ʻōlelo aʻoaʻo hoʻoponopono pilikia?
A: ʻAe, aia i loko o ke alakaʻi nā ʻōlelo aʻoaʻo hoʻoponopono no ka hoʻonui ʻana i ka helu o nā host IP i kākoʻo ʻia ma kahi pūnaewele a me ka hoʻoponopono ʻana i nā paio pool address overlapping IP.
