Packet Tracer use serial link betn two routers by default Hi there, Its the media type. Historically WAN links were pretty much always serial connections, to connect to the service providers csudsu youd typically run a serial cable from the router to the sps device. Ethernet is used internally within the organisatoin for the LAN, so the router has an ethernet port for that purpose. Nowadays there is less use of serial interfaces, as WAN connections use ethernet hand offs from service providers for MPLS, Metro Ethernet etc. There is usually a fibre device installed by the service provider, and an ethernet cable from that goes to the router. So the use of serial interfaces for new connections is now less common, they are still loads out there though. As for why PT defaults to a serial link between two routers, I guess thats what the developers picked as a default. Probably because connecting two routers together is usually a WAN type connection. And ICND1 2 cover a lot serial interface stuff, and Frame Relay, which also runs over serial. Hope this helps, MJ.
