Core Knowledge Question of the Day: 27 May 2009

R3#sh frame map
Serial0/0 (up): ip 155.3.0.3 dlci 503(0x1F7,0x7C70), static,
broadcast,
CISCO, status defined, active
TCP/IP Header Compression (inherited), connections: 218959117
RTP Header Compression (inherited), connections: 218959117

R5#sh frame map
Serial1/0 (up): ip 155.1.0.5 dlci 305(0x131,0x4C10), static,
broadcast,
CISCO, status defined, active
TCP/IP Header Compression (enabled), connections: 256
RTP Header Compression (enabled), connections: 256

Given the above output, what is the fundamental difference between the TCP and RTP header compression configurations on R3 and R5?

Highlight for answer: On R3, TCP and RTP header compression have been enabled on the interface level as indicated by the ‘inherited’ description in the ‘show frame-relay map’ output.  On R5 it has been enabled via the frame-relay map map statement(with the keyword ‘compress’).
