How do I route ether3 to ether4 (tagged vlan) on CCR

RouterOS Forwarding Protocols

(I have re written this post)

If I plug a carrier into ether 3 and I have ether4 with a tagged vlan say vlan10

[windows vlan10]–[XEN host]–[ trunk cisco4948 trunk]–[vlan10 ether4 microtik1036 ether3] --[point to point–carrier-voip sbc

How do I get ether 3 to talk to VLAN10 which is tagged.

For example:

In Winbox I can ping voip SBC at the end of a point to point link which is connected to ether3
In Winbox I can ping a XEN virtual machine on vlan10

How do I get the 2 to talk when one is an ip on interface (ether3)
Other is IP on vlan10 on ether4

and spanning tree has to be off on the point to point link on ether3

May be a bridge ether3 and ether4 if so how?

I could change to untagged may be on vlan10 but I am still confused how I get ether3 and vlan10 to talk

Thanks

CCR its a router, i think you are comparing to a cisco switch

Well my cisco’s doing switching and routing.

I know the CCR is a router I have 8 of them 4 are the new 72 core 10Gb/s

This is only a VLAN trunking port, I can do that on either a Cisco switch or Cisco router.

So does the CCR do the same?

I suppose what I am asking:

If I plug a carrier into ether 3 and I have ether4 with a tagged vlan say vlan10

[windows vlan10]–[XEN host]–[cisco4948]–[vlan10 ether4 microtik1036 ether3] —[point to point—carrier–voip sbc

How do I get ether 3 to talk to VLAN10 which is tagged.

For example:

In Winbox I can ping voip SBC at the end of a point to point link which is connected to ether3
In Winbox I can ping a XEN virtual machine on vlan10

On just about any MikroTik, you can bridge the VLAN subinterface of one physical interface to the vlan subinterface of another physical subinterface. Or you can bridge a physical port to a vlan subinterface if you need untagged to tagged.

Here is an example from the 1072 in our lab
For tagged to tagged, just create a bridge and add the vlan interfaces like this:

[admin@IPA-LAB-CCR1072] > export
/interface vlan
add interface=sfp-sfpplus3 l2mtu=9212 name=vlan10-sfpplus3 vlan-id=10
add interface=sfp-sfpplus4 l2mtu=9212 name=vlan10-sfpplus4 vlan-id=10
/interface bridge
add name=Vlan10-bridge
/interface bridge port
add bridge=Vlan10-bridge interface=vlan10-sfpplus3
add bridge=Vlan10-bridge interface=vlan10-sfpplus4

The CCR1072 can absolutely do this and should perform fairly well, but A 10 gig switch would be more ideal if you have a choice between one or the other. The CCR is CPU based routing platform and can only handle layer 2 forwarding by bridging using the CPU. On most Cisco L3 switches like 4500,6500, etc, ASICs handle the L3 forwarding so that a port can function in either routed or switched mode.

Do you guys do remote support for fee? i.e login and fix it :slight_smile: if I explain set up

in an ideal world I would prefer to remove the router and do it on the 4948.

Tony,

We absolutely do. Please go to http://www.iparchitechs.com/techsupport/ for contact information or send me a PM with your contact info. You can also email us at consulting[at]iparchitechs.com.

Thought the CCR supports FASTPATH, so if you bridge the VLAN sub-interfaces then it a direct connection not utilizing the kernel.

Can you expand on this? Shouldn’t be much CPU utilization… right?

"Fast path allows to forward packets without additional processing in the Linux kernel. It improves forwarding speeds significantly. "
