Woodworkers, when hearing the word Router think of something that can effortlessly carve a groove into wood.
So, who's right?
- chris_wot 11y agoWell, all of them. A router in computing parlance is just any device that forwards packets between networks. So the first two examples are both routers.
- Gracana 11y agoI'm disappointed that you didn't show some text for your last example. I'll make a little marble run for you. __________ ________ \ \ \ \ \ | | | | \ \___ \_____
- cnvogel 11y agoThanks, your help in visualizing woodwork is really appreciated ;-).
- Decade 11y agoOld network guys remember when networks were not all IP, and there were Novell IPX routers, and AppleTalk routers, and DECnet Phase IV routers, and CLNP lived on for a while due to phone carriers and IS-IS. And even in IP, BGP is only the latest in a long, sad story of routing protocols, and other protocols are usually used inside networks… including IS-IS.
- kjs3 10y agoIS-IS (in a somewhat variant form) lives on in 802.1aq.
- jlgaddis 11y agoWhy not just have GTT send you a default route if you're gonna run BGP at all?
