| Apr 13, 2020 at 4:06 | comment | added | Ron Maupin♦ | There is a complicated answer to that question, but in general, no, and you have a misconception about a "default" path. Most Internet routers have a full knowledge of the Internet routing table and do not use default paths. The very idea of IP was that a packet will be routed one router at a time to the destination in case there is a disaster and one path fails then the packets can be forwarded along a different path with no need for intervantion. This was a great leap over the old circuit switching networks. | |
