Hi all,<BR>
<BR>
<BR>
<BR>
I have some doubts about ISC DHCP. Software version is 3.0.1.<BR>
<BR>
<BR>
<BR>
1) Does ISC DHCP server sends “Vendor Specific Information” (DHCP option 43) as “encapsulated vendor specific option”? <BR>
<BR>
2) Based on what info DHCP client can identify that, whether the data following option code 43 is encapsulated or not?<BR>
<BR>
3) If dhcpd.conf contains only one DHCP client configuration entity for one VCI (vendor class identifier), will it be encapsulated form or not?<BR>
<BR>
<BR>
<BR>
I am really new to DHCP. All answers are greatly appreciated.<BR>
<BR>
<BR>
<BR>
Thanks in advance,<BR>
