As the topic does not work TRUNK between the CISCO 2950 in CCR1009.
CISCO VLAN does not pass coming from CCR1009.
Cisco 2950 port TRUNK:
!
Interface GigabitEthernet0/1
description UpLink
switchport mode trunk
switchport nonegotiate
no cdp enable
spanning-tree portfast trunk
ip dhcp snooping trust
!
CCR1009 only works as a router gateway
Mikrotik TRUNK
[admin@MikroTik] > interface vlan print
Flags: X - disabled, R - running, S - slave

NAME MTU ARP VLAN-ID INTERFACE

0 vlan2 1500 enabled 2 ether6-TRUNK
1 vlan3 1500 enabled 3 ether6-TRUNK
2 vlan5 1500 enabled 5 ether6-TRUNK
3 vlan6 1500 enabled 6 ether6-TRUNK
DHCP server associated with each VLAN

Does anyone have running TRUNK between Cisco and CCR1009, does it work?

Two things to try on trunk port on cisco:

switchport trunk encapsulation dot1q

or

global config: vlan dot1q tag nativ
3

encapsulation type available on 2950 is dot1q,so by default it is enabled on the port

What Vlans have you added to the cisco. What Vlans are allowed on that port.
sho vlan

Did you try to tag native vlan ? Do you have the vlans created on switch ? does the port goes up ? Do you see MikroTik in

show cdp neig fa x/y det

?


Do you see any errors in:

sh int status fa x/y

We have many mikrotik => cisco trunks with no problem.
