802.1q trunk between 4451x and 2960

Hello! I cannot get my devices to communicate on anything outside of (native) vlan 1. Typically, I configure sub-interfaces, but I have found out that does not work. I am researching EVCs/Service-instances, but have not found a successful solution. My router config looks like:

interface GigabitEthernet0/0/2
 no ip address
 negotiation auto
 service instance 1 ethernet
  encapsulation dot1q 1
  rewrite ingress tag pop 1 symmetric
  bridge-domain 1
 !
 service instance 2 ethernet
  encapsulation dot1q 2
  rewrite ingress tag pop 1 symmetric
  bridge-domain 2
 !
 service instance 3 ethernet
  encapsulation dot1q 3
  rewrite ingress tag pop 1 symmetric
  bridge-domain 3
 !
 service instance 4 ethernet
  encapsulation dot1q 4
  rewrite ingress tag pop 1 symmetric
  bridge-domain 4
 !

 !

**ommited config**

!
interface BDI1
 ip address 10.226.80.254 255.255.255.0
 ip policy route-map FILTER
!
interface BDI2
 ip address 10.226.84.254 255.255.254.0
 ip policy route-map FILTER
!
interface BDI3
 ip address 10.226.88.254 255.255.254.0
 ip policy route-map FILTER
!
interface BDI4
 ip address 10.226.92.254 255.255.254.0
 ip policy route-map FILTER
!

Any thoughts as to what is wrong?

Thank you in advance.

Hi,

May i know did you try with SVI model like below configuration. Also I could see that the "trunk" is not enabled on the interface.

Eg:

Switch (config)# interface gigabitethernet0/0/2

Switch (config)# switchport mode trunk

Switch (config)# switchport trunk allowed vlan none

Switch (config-if)# service instance 2 Ethernet

Switch (config-if-srv)# encapsulation dot1q 2

Switch (config-if-srv)# rewrite ingress tag pop 1 symmetric

Switch (config-if-srv)# bridge-domain 2


Switch (config)# interface vlan 2

Switch (config-if)# ip address 10.226.80.254 255.255.255.0
