For ISL, I know they are trying to phase that out. For the exams, they are based on dot1q..... Even if I had all cisco equipment, I'd try to go with standards because you never know down the road where you may need to use another vendor. I wouldn't use EIGRP if given a choice, I'd go with OSPF or RIPv2.

To be fair to Cisco and maybe I'm way off here. But it seems they do come out with a way to do things first which then become a standard that they have to follow.

Yes, and then they keep their proprietary implementation instead of phasing it out, and no one migrates to the standard one which leads to vendor lockin.
