Hey guys,
I passed my CCNA exam this past Thursday, and I'm looking to start studying toward the CCNP. I wanted to ask about my home lab, and because I didn't see any equipment that I have in any of the FAQs, I figured I would post. You guys are always so help ful

My current lab equipment:
1 - 2610XM
2 - 2650XM
1 - 2950 Switch
1 - 1721
What would you say that I would need to add to this lab in order to make it through the entire CCNP labs? Would you say that adding a 3550 would be enough, any recommendations are greatly appreciate, thanks in advanced
