Wired Intelligent Edge

Hello,

I have my first project using VSX including routing functions there in VSX stack. Basic idea in setup is quite same which is illustrated in techdoch 
Active-active layer 2

 (edge connections are mostly L2 because of several non routable protocols in several vlan's)

At this point where I have created only five SVI's to vlans and proper active-gateway ip/vmac configs, everything works just fine and routing to internet through transit network works as expected but...
As techdoc mentioned above says, there can be only 15 vmac declarations in VSX instance, I will face the fact that I will have around 14pcs of vlans/vid's without vmacs to use vsx as default router..  As far as I have understood correct I can have same active-gateway declaration in vsx's svi without having VMAC but how absence of VMAC affect to routing?

You can reuse the virtual MACs on your active gateways--they're on different networks and it will not cause any problems.  All of my active gateways have the same virtual MAC.  There should be a note about this in the VSX best practices guide.

Edit: See page 15 of the VSX Best Practices Guide.

Thank you for your reply!

Now when you pointed out that guide I remembered  to read that a while ago but forgot that part :)

System seems to work fine now.
