icon ipv6 /127 prefix problem27.12.2012. u 22:09 - pre 137 meseci
Jel uspeo neko da natera mikrotik da rutira kroz 127 subnet ?

Dobili smo od TS wan block/127 i kada napravim default gateway prijavljuje mi da je unreachable. Pretpostavljam iz razloga sto u ipv6 u ruting tabeli napravi mrezu sa adresom gatewaya.

Ili sam nesto prevideo ...

Druga strana je sigurno dobro podesena jer sa drugih ipv6 mreza dobijam reply od TS rutera.

BTW interesantno je da ipv6 sa akademske mreze ide preko Njemacke ka Telekomu :)

kako si dodao def.rutu? ja s njima radim BGPv6, pa def.rutu dobijam BGP-om...

Jao, zasto 127?! Sta fali /64? ...lelekom

Proveri da li se izvrsi neighbour discovery. Imao sam slican slucaj, gde je pomoglo dodajanje mac-a u neighbor cache tabelu.

/64 bi bilo "vaste of addresses" :)

Dali su mi drugi WAN /126 i sve radi.

[halen@gw1-rb1100] > /tool traceroute 2001:8c8:0:2::4
# ADDRESS RT1 RT2 RT3 STATUS
1 2a00:e90::c:0:0:0:9 5ms 5ms 5ms
2 2a00:e90::212:200:16:44 9ms 9ms 9ms
3 :: 0ms 0ms 0ms
4 :: 0ms 0ms 0ms
5 2001:8c8::2:0:0:0:4 23ms 15ms 9ms

Dakle MT ima problem sa /127 ptp linkom.

Ricky, kad idem kroz ipv6 do tebe imam 5 hopova. Kroz ipv4 imam 11 :)
