Problema e cam asa: am doua clase de /23, AS, bgp cu providerii.. toate nebuniile. Pana acum am alocat clientilor doar ip/32, dar acum s-a trezit cineva ca vrea o clasa /29. Cum trebuie sa fac ?  :dontgetit:

Stai că nu mă prind. Tu ai o groază de IP-uri cărora le dai net.
Cel care vrea subreţeaua aia /29 are şi el router or something?

Păi BGP-ul īl ai către ISP. O rută statică spre routerul Gigelului /29 are ceva? Smiley

pai.. nu are nimic, dar mai exact.. cum?

impart a doua clasa de /23 care oricum nu o folosesc in clase mai mici si trebuie sa-i dau lui un ip separat spre care sa-i rutez clasa de /29 ?

Ii faci o ruta statica pentru fiecare ip. Pana te gandesti la ceva mai bun :)) Mor de rās

Sau fai asa:

http://jodies.de/ipcalc?host=81.96.229.0&mask1=23&mask2=29

Alegi un subnet dala, si i-l routezi.

Acum nustu ce sa zic, daca majoritatea oricum au doar un ip, nu cred ca 6 rute statice in plus e mare chestie. Mi se pare mai convenabil decat sa-ti tai reteaua in bucati Smiley

Nu dai nici un IP. Rutarea se face spre superreţele, reţele, subreţele, sau IP-uri. Dai spre adresa de subreţea.

Pai ala cu routeru tre sa aiba un ip. De exemplu, ii dai routerului aluia un ip oarecare (nu cred ca merge cu ip privat), si faci o ruta statica catre ip-ul ala

route add -net 81.96.229.0 netmask 255.255.255.248 gw ip-ul_routerului_aluia

rtfm man route

Oblio, un exemplu practic? Smiley

Same stuff.
Dacā reţeaua e 193.24.21.0/24, subreţea o să fie 193.24.21.0/29, adică 193.24.21.1 - 193.24.21.6 (ca adrese valide). Dacă Gigel are routerul ca 193.24.21.6, atunci pui rută către 193.24.21.6. Mai departe face Gigel routarea...

A postat Gheorghe pānă să zic, dar modelul lui e bun:
route add -net 193.24.21.0 netmask 255.255.255.248 gw 193.24.21.6

Dacă Gigel vrea neapărat să economisească IP-uri publice, ceea ce este foarte normal de altfel, poţi să-i dai 192.168.0.1 or something, ruta devine:
route add -net 193.24.21.0 netmask 255.255.255.248 gw 192.168.0.1
el pune o rută default spre tine, ceea ce iarăşi e normal, şi bagă toate IP-urile alea īn spate. Aşa economiseşte un IP public...
