Transporting VLANs over VPLS??

Tue Nov 13, 2012 10:21 pm

Hello,

I'm new to the Mikrotik world so I would greatly appreciate any help you might be able to lend me. I have to say that I've had an eye opener having dug into what RouterOS can do, wow! I am trying to set up (LAB) a configuration to transport several vlans over a VPLS Tunnel. I can/have set up the VPLS Tunnel and verified Layer 2 connectivity between both sides. What I can't seem to get working is transporting one or more vlans. Interesting, and likely I am not understanding what I am seeing, I do show traffic on the vlans on both the vpls and ethernet interfaces. However, I do not have layer 2 connectivity. I understand MTU size plays a crucial role. I have played around with MTU settings for MPLS, VPLS, etc (my config will probably look hacked up now). I'm obviously missing something. It could even be how I have my VLANs set up. Once I get it working in my lab I'll end up deploying across my backbone/Cisco. I do understand that, again, MTU is critical and that ALL interfaces transporting traffic must have a minimum MTU; while I've found there is some difference of opinion as to what that should be. I run Jumbo Frames to support WiMAX over my Dragonwave backhaul. I'll post the config of both sides and a few screen shots to visualize.

Re: Transporting VLANs over VPLS??

Wed Nov 14, 2012 8:33 pm

Ok, I seem to have my VPLS Tunnel up and running and VLANs operating over the tunnel. If I connect a laptop to access port on switch 2 and modem to access port on switch 1 (both vlan 520) I can pull DHCP, and browse pages, send email, etc. However, pinging the other side of the /30 I do get packet fragmentation. This forum post http://forum.mikrotik.com/viewtopic.php?f=14&t=62293 talked about changing the MTU on all LDP interfaces. I'm not entirely clear on what all the LDP interfaces are. I assume (I know, don't... so I ask), the physical port which carries the VPLS and VLANs (ether2), the MPLS interface, and the VPLS interface. Does this also include the Bridge interface? Or do I have it all wrong. Could you direct me to the interfaces I need to change? BTW, when I attempt to change the MTU on the physical interface ether2, I get an error. I've included a screenshot to visualize what I see. Thanks for any help you can send my way.

Curious on your final results, as this is what I'm currently hung up on. What was it you found in the end that got VLAN transport across to endpoints working?
