Why I am receiving a route record indication?

Hi all,

I am sending a Remote AT Command Request (0x17) to configure the sample rate (IR) to 1 second (0x03E8) using the following frame:

7E
00 11
17
00
00 13 A2 00 40 AA D0 06
FF FE
02
49 (‘I’) 52 (‘R’)
03 E8
EE

Beyond I get the response of ZigBee IO Data Sample Rx Indicator (0x92), I am getting a route record indicator (0xA1). I am getting he following frames as the responses:

Route Record Indicator:
7E 00 0D A1 00 13 A2 00 40 AA D0 06 5F EF 00 00 9B

ZigBee IO Data Sample Rx:
7E 00 12 92 00 13 A2 00 40 AA D0 06 5F EF 01 01 00 10 00 00 00 98

So, I would like to know, why am I receiving the frame 0xA1. This also happened when I sent another Remote AT Command Request (0x17).

I will be glad if you could help me.

Bests.
