Gulu Lalikulu la BGPview
Magulu akuluakulu a BGP amapereka mwayi kwa tagging njira ndi kusintha BGP routing mfundo pa ma routers. Madera akulu a BGP amatha kuwonjezeredwa kapena kuchotsedwa mwa kusankha pamagulu akulu omwe amayenda kuchokera pa rauta kupita ku rauta. Pamene midzi ikuluikulu imatchulidwa m'malamulo, imatchulidwa ngati nambala zitatu zomwe sizinali zoipa zolekanitsidwa ndi ma colon. Za exampndi 1:2:3. Nambala yoyamba imayimira gawo la Global Administrator, ndipo magawo awiri ena onse amayimira gawo la Local Administrator.
Magulu akuluakulu a BGP amachita chimodzimodzi ndi anthu omwe amakhala nthawi zonse ndipo amagwiritsidwa ntchito pazifukwa zofanana. Kuti mumve zambiri zagulu lalikulu la BGP, onani chikalata cha rfc8092.

Mndandanda Wamagulu Amagulu
Mndandanda waukulu wamagulu a BGP umagwiritsidwa ntchito popanga magulu amagulu akuluakulu omwe angagwiritsidwe ntchito pagawo lofananira pamapu amayendedwe. Mutha kugwiritsa ntchito madera akuluakulu kuti muwongolere ndondomeko yamayendedwe. Ndondomeko yoyendetsera njira imakupatsani mwayi wosefa mayendedwe omwe mumalandira kapena kutsatsa, kapena kusintha mawonekedwe amayendedwe omwe mumalandira kapena kutsatsa. Mukhozanso kugwiritsa ntchito mndandanda waukulu wamagulu kuti mufufuze madera akuluakulu mwasankha. Pali mitundu iwiri ya mndandanda waukulu wamagulu:

  • Minda yokhazikika yamagulu ambiri-—Imatchula madera akuluakulu.
  • Mindandanda yayikulu yamagulu-Imatchula madera akuluakulu pogwiritsa ntchito mawu okhazikika.

Mndandanda waukulu wamagulu ukhoza kutchulidwa kapena kuwerengedwa. Mindandanda yonse yotchulidwa komanso yowerengedwa ingakhale yokhazikika kapena yokulitsidwa. Malamulo onse a ndandanda yamagulu akuluakulu amagwira ntchito pama ndandanda akuluakulu ammudzi, kupatulapo kuti palibe malire pa kuchuluka kwa ndandanda yamagulu omwe angasankhidwe.

Zindikirani: Magulu opitilira 99 (oyambira 1-99) omwe ali ndi ndandanda wamagulu akulu akulu ndipo 401 (oyambira 100-500) omwe ali ndi mindandanda yayikulu yamagulu akhoza kukhazikitsidwa. Minda yayikulu yotchulidwa yamagulu ilibe malire.
