Internetworking for system administrators

I'm a senior-level Unix sysadmin and IT manager. I'd like to fill up one big gap in my experience but I'm not sure the best way to do it: large-scale networking.
I understand LANs, VPNs, switching, etc. and the basics of Internet routing, but I've never had hands-on time on something that speaks BGP, or learned IOS or JunOS, that kind of thing. But I'm in a small company, so it's not like I'll have some hands-on time on a Catalyst 6500, let alone carrier-level stuff.
Reading about the new Cisco CRS-3
got me thinking about that gap in my experience. Years ago I used to be able to find my way around looking-glass servers and oregonix's route-views service but I haven't had need to in a while.
I'm not interested in certifications, I don't think -- this isn't about finding other work, it's about rounding out my knowledge so I can see what's going on. What's a good approach to get up to speed on both the theory and practice of "advanced" networking?
