Portál AbcLinuxu, 6. listopadu 2025 12:14
Ahoj, mam takovej divnej problem, mam 2 identicky mikrotiky s poslednim FW, oba v podstate nakonfigurovany stejne, firewall je vypnuty, pouze maskarada, je to firma A a B mezi nima je EoIP, na firme A mam VLAN10 10.0.1.1 (plus nejaky dalsi), ale o ty me nejde, mikrotik ma 10 portu rozdelenych do switch1 a switch2, vsechny porty jsou v bridge, VLANy maji nastaveny interface BRIDGE. SFP1 je trunk na switch, eth1 je internet, eth2 je trunk do dalsiho mikrotiku AP, eth3-9 jsou nastaveny na VLAN10. Na Eth3-5(interni switch1) mam problem co budu popisovat. Na eth3-5 pripojim linux server (10.0.1.20) a pustim ping na seznam.cz, s kazdym novym pingem se dotazuje DNS serveru mikrotiku na adresu a tam nastavaji timeouty
1) Firma:A, Port:ETH5, DNS:10.0.1.1, pingy se posilaji asi po 5ti sekundach. Projde ping(0-7), pak dotaz na DNS(timeout na DNS odpoved, neni prirazena vlan10)(8-9), pak projde ping(10-15), pak (16-17) zase DNS timeout, ....
Toto je zaznam ze snifferu z mikrotiku:

2) Stejne jka 1), pouze na serveru nastavim DNS na 10.0.2.1 (coz je firma B pres EoIP) a vse jede jak ma
3) Stejne jak 1), pouze na serveru nastavim DNS na 172.16.20.1 (coz je adresa VPN na mikrotiku) a vse jede jak ma
4) Stejne jak 1), pouze na serveru nastavim DNS na 8.8.8.8 a vse jede jak ma
5) Pokud nastavim DNS na 10.0.1.1(VLAN10) a pripojim se na Eth6-9 coz uz je interni switch2 nebo se pripojim do AP nebo switche, ktere jsou pripojeny k mikrotiku pres trunk a taky maji na portech nastaveny vlany, tak vsechno jede jak ma
6) Pokud zmenim adresu serveru na 10.0.2.20 a prijim do stejne konfigurace do mikrotiku firmy B na stejne porty eth3-5, tak taky vse funguje jak ma
- VLAN maji interface BRIDGE(ten je pouze vytvoren a neni vnem zadne dalsi nastaveni)
- Interni porty switch mikrotiku jsou nastaveny tako:
# NAME SWITCH VLAN-MODE VLAN-HEADER DEFAULT-VLAN-ID
0 ether1 switch1 disabled leave-as-is auto
1 ether2 switch1 secure add-if-missing auto
2 ether3 switch1 secure always-strip 10
3 ether4 switch1 secure always-strip 10
4 ether5 switch1 secure always-strip 10
5 ether6 switch2 secure always-strip 10
6 ether7 switch2 secure always-strip 10
7 ether8 switch2 secure always-strip 10
8 ether9 switch2 secure always-strip 10
9 ether10-service switch2 disabled leave-as-is auto
10 switch1-cpu switch1 secure leave-as-is auto
11 switch2-cpu switch2 secure leave-as-is auto
- VLANy na switch mikrotiku jsou nastaveny takto:
# SWITCH VLAN-ID PORTS
0 switch2 10 ether6 ether7 ether8 ether9 switch2-cpu
1 switch1 100 ether2 switch1-cpu
2 switch1 110 ether2 switch1-cpu
3 switch1 10 ether2 ether3 ether4 ether5 switch1-cpu
4 switch1 1 ether2
Uz stim laboruju asi den a porad nic, zkousel deaktivovat EoiP a vsechny ostatni VLANy krom VLAN10, odpojil jsem vsechny TRUNKy a porty nastavil na VLAN10, ale proste interni switch 1 na mikrotiku firma A se chova nejak divne.
Nejaka rada prosim, uz fakt nevim ?
