You didn't read his example well enough. He said, Say you have two segments connected to a router; one segment off of e0 and one segment off of e1. If a host on the e0 segment sends a frame to a host on the e1 segment and a collision occurs on the e1 segment before reaching the destination

Let me try, The CCIE tests expect you to know that neither a bridge nor router re-transmits if a frame experiences a bit error or gets lost somehow. Could you please clarify further? Thank you! There is distinct difference between bit errors and collisions. Retransmitting

Sure, it's retransmit if there's a collision. Cut-through switching will begin forwarding as soon as the MAC is read, but it must still keep a copy in memory in case of collision. I guess I don't know for certain, but I would assume... Message Posted at:

You're right. A bridge is not going to retransmit any frame that failed to reach it's destination. That will be up to the appropriate protocol on the originating host. Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=43461t=43459

Regardless of whether a router is configured for bridging or routing, it must send an Ethernet frame successfully, without a collision. A half-duplex Ethernet interface (whether on a bridge, switch, router, server, or PC) monitors for a collision while sending. If a collision occurs, the

I agree with you transparent bridges are just that, transparent. Any retransmittal of corrupt or lost frames would need to be done by the end station AFAIK, (with ethernet) even if a device receives a corrupt frame, at layer 2, it simply discards it it doesn't request retransmittal

If an Ethernet device receives a damaged frame, it silently discards it. That is true. But a half-duplex Ethernet sender knows when a collision occurs with a frame that is sending and retransmits. That's the CD part of CSMA/CD. If a frame got damaged for some other reason, say noise or

I'm doing my written tomorrow, I've studied that retransmits are part of the Host's job, especially in a TB network. TB's are stupid, they do no error recover or anything similar. You are correct Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=43469t=43459
