Despite having plenty of experience with IOS (and, to a lesser extent, IOS XE), we've never had Nexus equipment before, in particular not used NX-OS. As such, there's a bit of a learning curve to get things up and running.
This post (and probably some following ones) is what we've encountered in the setup of the Nexus equipment and will likely cover VDCs on the 7010s, vPC (Virtual Port-Channel) on the 7010s and 56128Ps and the FEXs, as well as some NX-OS differences.
MPLSDespite getting some licence sheets with PAKs (Product Activation Keys) for the MPLS feature set, these appear to have already been installed. However, the feature isn't activated by default and requires some work to do so.
First, in the admin VDC, the feature set must be installed:
n7k(config)# install feature-set mpls
Then, in the service VDCs (our backbone routing-only one is "cudn", the Cambridge University Data Network), the feature-set must be activated, along with the desired individual features:
n7k-cudn(config)# feature-set mpls
n7k-cudn(config)# feature mpls ldp
n7k-cudn(config)# feature mpls l3vpn
The MPLS features then become available in that VDC.
