I think that I shall never see
a graph more lovely than a tree.
A tree whose crucial property
is loop-free connectivity.
A tree that must be sure to span
so packets can reach every LAN.
First, the root must be selected.
By ID, it is elected.
Least-cost paths from root are traced.
In the tree, these paths are placed.
A mesh is made by folks like me,
then bridges find a spanning tree.

This whole week I'll be going through IPv6 Advanced Training from Authorized Cisco Partner. The first day was more focussed on fundamentals and all which I have already went through during my CCIE R&S. But still picked up few new and nice things. Also R&S Lab was more focussed on Routing & Tunneling Techniques. Where this training is also looking at other aspects like WINDOWS/LINUX/MAC side configurations which I never tried much earlier. Also other important deev dives on topics like DHCPv6, DNSv6, v6 PE-CE & v6 mobility etc. Following is the lab topology that each candidate have access to. I'll post more details next week.
