Does someone know HSRP 's mac address used when we have two physicals routers connected to a LAN ?
i.e: fa0/0 of router 1 is connected to SW1
fa0/0 of router 2 is connected to SW1
when we ping the logical HSRP addess we will se witch address mac in the arp and mac-address-table ? router1'mac or router2's mac or another one ?
thank you ganeshh, but what is the argument to change to strainght cable ? i will gain in performance ? i'm connected in half-duplex but with 100 MB.
to switch to full duplex it will add something ?
Half-duplex is used to describe communication where only one side can talk at a time. Once one side has finished transmitting its data, the other side can respond. Only one node can talk at a time. If both try to talk at the same time, a collision will occur on the network.
As you can understand, this method of communication is not very efficient and requires more time to send/receive larger amounts of data.
On the other hand, full-duplex is used to describe communication where both sides are able to send and receive data at the same time. In these cases, there is no danger of a collision and therefore the transfer of data is completed much faster.
Hope to Help !!

The MAC address 00-00-0c-07-ac-xx is reserved for HSRP, and xx is the HSRP group number in hexadecimal. so make sure you're comfortable with hex conversions. The group number is 5, which is expressed as 05 with a two-bit hex character. If the group number had been 17, we'd see 11 at the end of the MAC address - one unit of 16, one unit of 1.
