Comment 1 for bug 1773197

nameservers should be in /etc/resolv.conf is 1.1.1.1 2.2.2.2
since control node is not sending in the proper format[when more than dns servers are configured] ,agent discards it and uses ipams dnsservers info.

agent dhcp discard message:

018-07-18 07:41:35.786 DhcpError: VM 192.168.1.3 : Invalid DHCP option 6 data : 1.1.1.12.2.2.2is invalid controller/src/vnsw/agent/services/dhcp_handler.cc 1169

space should be there between dns-servers in dhcp-option-value
