Mapping incoming DLCI to VLAN

[GM2005]

Hi

I want to map incoming traffic on a particular DLCI to a particular VLAN on the network. DOes anyone have a link or suggestion on how to achieve this? A link will be fine, i'm not too lazy to look but cannot find one on Cisco. I will have traffic coming in from lots of different DLCI's and need to seperate them into seperate VLAN's.

I think you would have to do this wil bridge-groups and frame-relay sub-interfaces. Create a VLAN Trunk between your WAN router and your Switch that has the VLAN's on it:

!Switch config
interface FastEthernet0/1
switchport
switchport encapsulation dot1q
switchport mode trunk
switchport nonegotiate
switchport trunk allowed vlan 10,20
!

!Router Config
bridge-group 10 protocol ieee
bridge-group 20 protocol ieee
!
interface FastEthernet0
!
interface FastEthernet0.10
encapsulation dot1q 10
!
interface FastEthernet0.20
encapsulation dot1q 20
!
interface serial 0
encapsulation frame-relay
!
interface serial 0.10 point-to-point
frame-relay interface-dlci 216
bridge-group 10
!
interface serial 0.20 point-to-point
frame-relay interface-dlci 217
bridge-group 20
!

I am not 100% sure of the syntax but that is the only way I can thing of doing it..

Why do you want to pass VLAN's over Frame-Relay anyway? Do you have non-routable protocols? If this is for an IP Network then I would recommend routing it, that is what the routers are designed to do.....

Oh, I know. Its coming from our MPLS cloud through a managed firewall and we have a strange way of provisioning it.

Anyway, thanks loads for the help and config, it really is appreciated.
