Specifying The Source Interface For Dns Packets; Displaying And Maintaining Ipv4 Dns - HP 6125G Configuration Manual

Step
2. Set the DSCP value for
DNS packets.

Specifying the source interface for DNS packets

By default, the device uses the primary IP address of the output interface of the matching route as the
source IP address of a DNS request. Therefore, the source IP address of the DNS packets may vary with
DNS servers. In some scenarios, the DNS server only responds to DNS requests sourced from a specific
IP address. In such cases, you must specify the source interface for the DNS packets so that the device
can always use the primary IP address of the specified source interface as the source IP address of DNS
packets.
To specify the source interface for DNS packets:
Step
1. Enter system view.
2. Specify the source interface for
DNS packets.
