Need help with network design

[dilu]

Hello,

I am currently trying to find/test the best solution for the network below:

Switch X670-1,2,3 and 4 are already in use, switch X670-5 and 6 are new.
1,2,3 and 4 are currently connected with MLAG.

X670-1 and 2 are present on one site.
X670-3 and 4 are present on one site.
X670-5 and 6 are present on one (new) site.

I have the above set up in a testlab.

Should i configure EAPS or ERPS for this setup or can is simply use MLAG?
I am afraid i will get loops if I connect the switches like this.

Can anyone give me some tips how i can do this the most effectively.

Hello Dilu,

If you are planning on stacking the new x670s you can simply use MLAG and you will not experience any loops. The lag built for 1:16 and 2:16 will simply split to the current switches in deployment.

If they are separate switches then follow the same concept where they each have there own lag split to the MLAG peers.

If stacking is not being used then you can build a EAPS ring as long as the master is not one of the MLAG peers.

Hope this helps!
