Hello everybody!

I try to setup connectivity between RB2011 / CRS125.
Both devices have ether1 as trunk port for some VLAN networks (3000...3010).
And both devices have access port for VLAN 3001.


RB2011 have an VLAN Interface with DHCP Server.
If client get connection for access port from RB2011 - everything is OK, if from CRS125 - dhcp server show offered status of ip lease.
DHCP client running directly at CRS125 working without any problems. Static IP address (without DHCP) from both sides working fine.

DHCP Snooping and Port Isolation are disabled. With enabled features the result is same

Configuration attached to the post. RoS 7.2.3

Any ideas?

Problem was solved.

Solution is:
- disable another bridge and ports, that are not used. Both bridges were with the same admin-mac
- remove vlan interface from bridge

All fixes were from CRS side.
