SPAN
Ka taea e koe te whakamahi i te mahi SPAN hei tārua i ngā mōkihi mai i tētahi tauranga kua tohua ki tētahi atu tauranga i runga i te pana e hono ana ki tētahi pūrere aroturuki whatunga hei aroturuki whatunga me te rapurongoā.
Kāore a SPAN e pā ki te whakawhitiwhiti mōkihi i waenga i te tauranga pūtake me te tauranga ūnga. Ka tāruatia ngā mōkihi katoa e tomo mai ana, e puta mai ana hoki i te tauranga pūtake ki te tauranga ūnga. Heoi, ki te nui ake te whānui o te waka whakaata i te whānui o te tauranga ūnga, hei tauira, ki te aroturukihia e te tauranga ūnga 100Mbps te waka o te tauranga pūtake 1000Mbps, ka makahia pea ngā mōkihi.
RSPAN
Ko te whakaata tauranga mamao (RSPAN) te toronga o te whakaata tauranga ā-rohe (SPAN). Mā te whakaata tauranga mamao ka takahia te here e tika ana kia noho te tauranga pūtake me te tauranga ūnga ki te pūrere kotahi, ka taea ai e te tauranga pūtake me te tauranga ūnga te horapa i ngā pūrere whatunga maha. Mā tēnei, ka taea e te kaiwhakahaere whatunga te noho ki te rūma taputapu matua me te tirotiro i ngā mōkihi raraunga o te tauranga whakaata mamao mā te tātari.
RSPANKa tukuna ngā mōkihi whakaata katoa ki te tauranga ūnga o te pūrere whakaata Mamao mā te RSPAN VLAN motuhake (e kiia nei ko te Remote VLAN). E toru ngā wāhanga o ngā mahi a ngā pūrere:
1) Pūnaha Whakawhiti: Ko te tauranga pūtake whakaahua mamao o te pana, ko ia te kawenga mō te tārua i te karere tauranga pūtake mai i te putanga o te pana pūtake, mā te tuku whakamua VLAN Mamao ki waenganui, ki te pana rānei.
2) Pana Waenga: i roto i te whatunga i waenga i te pana pūtake me te pana ūnga, ka whakaata te pana mā te tuku mōkihi VLAN Mamao ki te pana e whai ake nei, ki te pana rānei i waenganui. Mena kei te hono tika te pana pūtake ki te pana ūnga, kāore he pana waenga.
3) Pātene Ūnga: Ka whakaata mamao i te tauranga ūnga o te pātene, ka whakaata mai i te VLAN Mamao ki te whiwhi karere mā te whakaata i te tauranga ūnga whakamua ki te aroturuki i ngā taputapu.
ERSPAN
Ko te whakaata tauranga mamao kua whakakīia (ERSPAN) he toronga o te whakaata tauranga mamao (RSPAN). I roto i tētahi wā whakaata tauranga mamao noa, ka taea te tuku i ngā mōkihi whakaata i te Papa 2 anake, ā, kāore e taea te haere mā roto i tētahi whatunga kua araia. I roto i tētahi wā whakaata tauranga mamao kua whakakīia, ka taea te tuku i ngā mōkihi whakaata i waenga i ngā whatunga kua araia.
Ka whakakōpikopikohia e te ERSPAN ngā mōkihi whakaata katoa ki roto i ngā mōkihi IP mā roto i te kauhanga GRE, ā, ka tukuna atu ki te tauranga ūnga o te taputapu whakaata mamao. E rua ngā wāhanga o ia taputapu:
1) Pūnaha Whakawhiti: te whakakāpōtanga o te tauranga pūtake whakaahua mamao o te pana, ko te kawenga mō te kape o te karere tauranga pūtake mai i te putanga putanga o te pana pūtake, mā te GRE kua whakakāpōtia ki roto i te tuku whakamua mōkihi IP, ka whakawhiti i ngā pana ki te kaupapa.
2) Whakawhitiwhiti Ūnga: ka whakaatahia te tauranga ūnga o te whakawhiti ki te whakaata mamao, ka whiwhi i te karere mā te whakaata whakaata, ā, i muri i te wetewete i te tauranga ūnga, ka tukuna te karere GRE ki ngā taputapu aroturuki.
Hei whakatinana i te mahi whakaata tauranga mamao, me taea te tuku i ngā mōkihi IP kua whakakāpōtia e te GRE ki te pūrere whakaata ūnga i runga i te whatunga.
Putanga Whakakī Mōkihi
E tautokona ana hei whakakōpaki i ngā mōkihi kua tohua i roto i te waka kua hopukina ki te pane RSPAN, ERSPAN rānei, ā, ka tukuna ngā mōkihi ki te pūnaha aroturuki o muri, ki te pana whatunga rānei.
Whakamutu i te Kete Tunnel
I tautokona te mahi whakamutu mōkihi kauhanga, e taea ai te whirihora i ngā wāhitau IP, ngā kopare, ngā urupare ARP, me ngā urupare ICMP mō ngā tauranga whakauru waka. Ko ngā waka ka kohia i runga i te whatunga kaiwhakamahi ka tukuna tika ki te pūrere mā roto i ngā tikanga whakakī kauhanga pērā i te GRE, GTP, me te VXLAN.
Te Wetewete i ngā Pane o VxLAN, VLAN, GRE, MPLS
I tautokona te pane VxLAN, VLAN, GRE, MPLS i tangohia mai i roto i te kete raraunga taketake, ā, i tukuna atu te putanga.
