Hi, can you help me on this?
If the command below is issued on the s0/0 interface,
what is the correct behavior.
router(config-if)#ip tcp header-compression passive
a)The router will only compress outgoing TCP packets if incoming
TCP packets on the same interface are compressed.
b) The L2 header will be compressed and therefore cannot be used
for WAN switching networks such as Frame Relay.
c) The L2 header will be left intact and therefore can can be used
for WAN networks such as Frame Relay.
I thought that options a) and c) are correct.
However, the book states that a) and b) are the answer for this exercise.
According to the "BCRAN", Cisco Press book, I see that the L2 header
information is left intact when tcp header-compression is used.
What I am missing?
Options (a) and (c) are indeed correct. TCP header compression does not have any impact on the L2 header at all. Obviously, there is an error in the book.
