Mabapi le Tataiso ena

Tataiso ena e fana ka leseli mabapi le ho sebelisa Drain Mode ho Juniper Apstra, ka tlhophiso examples.
Drain Mode e o thusa ho hula sephethephethe ka bokhabane lisebelisoa ntle le ho koala litselana tsa boahelani tsa BGP.

Juniper Apstra e ts'ehetsa Drain Mode bakeng sa li-switches tse laoloang, e lumellang opereishene ho hula sephethephethe ka bokhabane ho tsoa lisebelisoa ntle le ho koala likamano tsa boahelani tsa BGP. Sena se kengoa ts'ebetsong ka ho fetola mokhoa oa BGP (limmapa tse kenang / tse tsoang), ho koala likou tse hokahaneng tsa li-server tsa L2, le ho koala likou tsa likhokahano tsa lithaka tsa MLAG. Ka ho sebelisa Drain Mode, basebelisi ba ka fokotsa palo ea sephethephethe se theohileng / se lahlehileng nakong ea ts'ebetso ena. Nakong ea tlhokomelo, khaello ea mosebetsi e sebetsanoa ke ECMP/MLAG hafeela ho ntse ho e-na le litsamaiso tse loketseng tse sa hlokeng letho.

E khothalelitsoeng Tšebeliso | 8
Tlhahlobo e entsoeng esale pele ea IBA (litlhahlobo tse thehiloeng ho sepheo) e fumaneha ho Juniper Apstra. U ka e kenya tšebetsong ka ho kenya probe e boletsoeng esale pele e bitsoang "Drain traffic anomaly". Theko e hlokahalang bakeng sa Threshold ho bps e sebetsa ka tsela e latelang:

Boleng ke kakaretso ea kakaretso ea sephethephethe ho li-hosted_interfaces tsohle
Sena ha se kenyeletse sephethephethe boema-kepeng ba tsamaiso ea Ethernet eo e seng karolo ea tekanyo ea lipatlisiso

Lihokelo tsena li kenyelletsa litsela tsohle tse lumelletsoeng tsa L3 BGP
Mahokelo a shebaneng le seva a koetsoe nakong ea Drain Mode 'me ha se karolo ea lipalo tsena
Moeli o hlalosa palo ea sephethephethe seo u lakatsang ho hlokomelisoa ka sona (ka holimo ho boleng) haeba lisebelisoa li le maemong a Drain.

Sena se etsa bonnete ba hore ha o etse ts'ebetso ea ts'ebetso ea 'nete ea ts'ebetso sesebelisoa se so kang sa tsoa ka botlalo.

Example
Spine1 e hokahane le li-switches tse 4 tsa makhasi, khokahano ka 'ngoe e tsamaisa mokhoa oa ho tsamaisa eBGP. Ts'ebetso eohle ea sephethephethe e ipapisitseng le ts'ebeliso (seva) e ntlafatsoa hape ka ECMP ho lihokelo tse ling mme lintlafatso tsa mantlha tsa boahelani ba BGP li ntse li sebetsa. Ka lab example ka topology e nyane, sena se sebetsa hantle 1.5KBPS sehokelo se le seng. Ka baahisani ba 4, kakaretso ea sephethephethe seo re lebelletseng ho lula ho sona lisebelisoa ke hoo e ka bang 6KBPS. Haeba re beha probe Threshold ka bps ho 10KBPS (10000), probe e hlahisa liphapang haeba ho na le ho feta 10K ho li-interfaces tsohle tse 4 tse kopantsoeng.

Phoso ena e lokela ho ba teng ka metsotsoana e seng mekae. Haeba phoso e sa hlake, sesebelisoa ha se ho Drain Mode ka botlalo. Hang ha bothata bo hlakohile, u lokolohile ho fetolela sesebelisoa ho boemo ba Ready ho se tlosa ts'ebetsong ka botlalo. Hape hoa khoneha hore u se ke ua bona phoso kaha e ka 'na ea hlaha' me ea nyamela ka potlako haholo.
