I acheived my CCNP about 2 years ago. I however ended up working in an environment with "other" vendor switches and routers. In short i have not worked with a Cisco router or switch in 2years. The current vendor switches and routers are somewhat similar to the cisco IOS but offcourse different.
Here is my question (s):
I would like to pursue my CCIE R&S. I'm overwhelmed. Where do I start?
What books to use?
Expected duration assuming i'm wholly dedicated and have an 8-5 job?
How difficult will this be knowing that i have not worked on cisco equipment in over 2yrs?
What Lab equipment do i need to have to make this realistic?
