Because Enterprise Networking is moving to cloud era, TRILL was designed to solve some old problems of traditional STP.
TRILL vs STP ---- 10 reasons to like TRILL.
1. Convergence time - milliseconds level for TRILL, seconds level for STP.
2. Scalability, using TRILL you can have up to 600 nodes in your topology, STP supports considerable less.
3. Bandwidth optimal usage, STP is blocking ports to disable loops, TRILL will keep all links available and load balance traffic using ECMP, no more bandwidth bottlenecks.
4. TRILL has unified control plane for unicast and multicast.
5. TRILL integrates a storm control method, in the header it contains hop count mechanism.
6. Flexible, agile, with TRILL you can implement fat tree design.
7. Spanning tree management, even if TRILL eliminates the need of STP, it can integrate STP domains.
8. Plug & play, TRILL components automatically discover and organize themselves.
9. High potential for further development, using IS-IS specific TLVs, TRILL can extend and carry extra parameters if necessary.
10. Simple management and configuration, it is easier to generate XML from TLV to make human inspection of the data possible, open API's.
