VRF routing table leakage? SMIPS issue?

RouterOS General
1

Hi,

I’ve been recently doing some basic labs using:

  • GNS3 running a couple of Cisco 3745 and 7200VXR
  • RB941 hAP lite RouterOS ver 6.31.1

The topology of the lab network is not really important, the point is I needed a VRF - a pair virtual ciscos had BGP sessions with the main routing table of the 941 and another pair had BGP sessions to a VRF on the 941.

VRF’s should be totally separate from the main routing table. For example if you have an ethernet interface with IP address 192.168.1.1/24 attached to VRF, subnet 192.168.1.0/24 is not reachable from the main routing table. That’s how it works with every vendor and with Mikrotik also. But not on my RB941! Can anyone test it on hAP lite or any other SMIPS?
Look at the screenshot:

On 951G-2HnD MIPSBE v 6.31.1 VRF’s are separated from the main table, just as they should be.

I mean version 6.33.1 of course…

This is a limitation of RouterOS 4/5/6. It will be resolved once RouterOS v7 is out.

Do you mean only smips?
I’ve been using VRF’s on mipsbe, x86 and powerpc since early routeros v5 and it always worked fine.

All current versions and all platforms have this problem.

:open_mouth:
Now I’m shocked.
I swear I’ve seen it working properly…

Maybe you tested from client to client then it works. Client to router does not work properly.
