- Edgecore-SONiC_20201229_070315_ec202006_bfn_65(Wedge100BF-32X)

Procedure:

Step 1. Add nameserver ip (8.8.8.8 as example) to /etc/resolve.conf

admin@sonic:~$ sudo vi /etc/resolv.conf

# This file is managed by man:systemd-resolved(8). Do not edit.
#
# This is a dynamic resolv.conf file for connecting local clients directly to
# all known uplink DNS servers. This file lists all configured search domains.
#
# Third party programs must not access this file directly, but only through the
# symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a different way,
# replace this symlink by a static file or a different symlink.
#
# See man:systemd-resolved.service(8) for details about the supported modes of
# operation for /etc/resolv.conf.

#nameserver 10.5.0.2
nameserver 8.8.8.8
search ap-south-1.compute.internal

Caution:

Result: The switch resolves domain name properly.
