Dear group,
For frame-relay tcp header compression, if I turn on the header compression
on the an interface, all the PVC will inherit the compression. The command
"frame-relay map ip addr dlci nocompress" is suppose to disable this inheritance.
Therefore, I try if one end of Frame Relay allow this inheritance, but another
end disable the inheritance, then TCP connection will be failed.
RouterA:
interface Serial0/0
ip address 192.168.1.1 255.255.255.0
encapsulation frame-relay
frame-relay map ip 192.168.1.2 204 broadcast nocompress
frame-relay ip tcp header-compression
!
RouterA#sh frame-relay map
Serial0/0 (up): ip 192.168.1.2 dlci 204(0xCC,0x30C0), static,
broadcast,
CISCO, status defined, active
RouterB:
interface Serial0/0
ip address 192.168.1.2 255.255.255.0
encapsulation frame-relay
frame-relay map ip 192.168.1.1 402 broadcast nocompress
frame-relay ip tcp header-compression
!
RouterB#sh frame map
Serial0/0 (up): ip 192.168.1.1 dlci 402(0x192,0x6420), static,
broadcast,
CISCO, status defined, active
TCP/IP Header Compression (inherited), connections: 256
RouterB#p 192.168.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 56/57/60 ms
RouterB#telnet 192.168.1.1
Trying 192.168.1.1 ... Open
Password required, but none set
[Connection to 192.168.1.1 closed by foreign host]
Anyone know why?
Best Regard,
William Chen
