Keep in mind that from a packet path forwarding decision process, these routers are speaking other protocols as well. There is dynamic information being shared between these closely coupled routers that lets them do the right thing.
Really? And what protocols are those?
Just thinking aloud here...
BGP OSPF HSRP ISIS EIGRP IGRP
just to name some of the various protocols that routers use to communicate with each other about the paths they know about. . dnsop resources:_____________________________________________________ web user interface: http://darkwing.uoregon.edu/~llynch/dnsop.html mhonarc archive: http://darkwing.uoregon.edu/~llynch/dnsop/index.html
