There is absolutely no reason that the networking equipment itself can't both operate the blockchain and keep a full copy.

But there's certainly something to be said for a vendor-supported solution that is inherent in the platform and requires no additional infrastructure. ...No additional infrastructure? Blockchains need multiple devices that are online and have enough storage to keep a full copy of the chain.
The storage requirements aren't particularly onerous. The entire Bitcoin blockchain is around 150GB, with several orders of magnitude more transactions (read: config changes) than you're likely to see even on a very large network. SSDs are small enough and reliable enough now that the physical space requirements are quite small.
You (presumably) trust your own routers. There is absolutely no reason that your own little network can't run your own private blockchain. In fact, for my use case of configuration management, you wouldn't WANT to use a single global public blockchain.They make sense in an environment with multiple sophisticated parties that sort of but not entirely trust each other, but there aren't as many of those as you might think.
