I have just completed reading the best practices for fabricpath and vPC+ and now I should create my first network design with Nexus devices..
If you take a look at the attached picture, you will notice that I divided each Nexus chassis in two virtual switch(VDC): one for core and the other for distribution. DIstribution layer will run Fabricpath and vPC+.
My initial idea was to use a dedicated M1+F1 card for each VDC. Then I decided to increase redundancy on the distribution VDC stealing some ports from the core M1 card(for the L3 interchassis connection) and some from the F1 (for vPC+ peerlinnk), assign them to the distribution VDC and splitting the vPC+ peer-link and L3 port channel on both the M1 and F1 cards.
In terms of benefits, in case M1 module in slot 3 fails , no convergence is required for the routing protocols . Moreover the peerlink is working on two distinct cards, so the possibility of losing the peerlink (and all member links) is reduced.
I am not sure this type of VDC fragmentation is supported by the way. In case it is possible, do you think this is a good idea?
