When there is no MAC address on serial interface, how the packets are routing ?

point-to-point, so no mac is needed. There is only one recepient. -- RFC 1149 Compliant.

Re: Serial no MAC [7:46429]
I would like to revise and extend your answer. :-) A serial interface is not *always* point-to-point. The answer actually depends on the Layer 2 protocol you are using. If you are using Frame-relay, you have a DLCI mapped to the IP address. On ATM you have a VPI/VCI combo. On point-to-point (PPP, etc...) the router, as Steven said, doesn't need a hardware address, since it is just sending and recieving on the interface where there is only one possible recipient, so the router only needs to know that the destination is out a specific p-t-p serial interface. -Tim Steven A.

yeah, there's no need for MAC address as such for PPP interfaces. but what about PPP over ethernet. - Original Message - From: timothy thielen To: Sent: Thursday, June 13, 2002 6:20 AM Subject: Re: Serial no MAC [7:46429] > I would like to revise and extend your answer. :-) > > A serial interface is not *always* point-to-point. > > The answer actually depends on the Layer 2 protocol you are using. > If you are using Frame-relay, you have a DLCI mapped to the IP address.
