Hello-I have been studying FR for a while now .cant find anywhere to
answer what these numbers mean,from the show frame-relay map
command-----
Serial1/2 (up): ip 172.16.1.4 dlci 401(0x191,0x6410),

I am understanding that the IP is the next hop address? and the DLCI
is local to the I/F you are on?
but what do 0X191 and 0x6410 mean? many thanks.

0x191 = 401 = DLCI
0x6410 = 25616 = It's a mapping to the serial interface, someone may be
able to confirm how this works a little bit better.

Hi,

Actually 0x6410 is the how the number is written by the protocol:
DLCI DLCI
110010|xx-0001|xxxx

The Xs represent the other header fields ( DE, EA, etc. ). If you exchange
Xs with 0, you got 0x6410.

Regards,
Gabriele

So 0x6410 is the same as 401?
