IP routing from a host connected to CM to a host on internet

Feb 06, 2009 0 Replies

Hi folks,



I would like a clarification regarding how IP routing happens between a host connected to a router which is in turn connected to the LAN i/f of a cable modem, and a host which is on the other side of CMTS (internet). I am confused because this is not a regular network of routers with the CM coming inbetween the host and CMTS.

---------------- | | | | | CM |------------------| CMTS |-------- INTERNET---B | | | | ------------- ----------------- | Etherent port -------------------------- | | ------- | R | ---------Host A -------


I wanted to trace an IP packet from Host A to Host B. Where will the DHCP server for hosts connected to router R be located and also will I be able to run a routing protocol like RIP amongst the routers connected to various cable modems in the cable n/w. I guess that since CMTS is at ISP, BGP would be used beyond from CMTS to outside.



Really appreciate if someone could please explain this in detail. I am having a lot of trouble understanding this.



Thanks, syuga
