[c-nsp] ECMP v Link Aggregation ofr MPLS

[Keegan Holley]

It depends on your platform, traffic and code versions.  Aggregated links and MLAG are the better option since they are simpler.  However they are more susceptible to bugs on certain platforms and traffic spread of course depends what kind of traffic flows will traversing the links.  It’s also easier to remove links from service with ECMP.  If you’re a transit AS you probably have enough diversity to ensure an even spread.  All things considered I’d choose aggregated links as well.
