Adding Custom A Records to an Avi DNS Virtual Service
Avi DNS can host manual static DNS entries. For a given FQDN, the user can configure an A, SRV, or CNAME record to be returned. This is accomplished via the Avi CLI as documented in this article.
The configure virtualservice dns-vs command shows there is already an existing static custom A record for FQDN ggg.avi.local.
: < configure virtualservice dns-vs
Updating an existing object. Currently, the object is:
+----------------------------------+-----------------------------------------------------+
| Field | Value |
+----------------------------------+-----------------------------------------------------+
| uuid | virtualservice-bc7c7fc6-583e-4335-8d33-ec4670771a85 |
| name | dns-vs |
| ip_address | 10.90.12.200 |
| enabled | True |
| services[1] | |
| port | 53 |
| enable_ssl | False |
| port_range_end | 53 |
| application_profile_ref | System-DNS |
| network_profile_ref | System-UDP-Per-Pkt |
| se_group_ref | Default-Group |
| east_west_placement | False |
| scaleout_ecmp | False |
| active_standby_se_tag | ACTIVE_STANDBY_SE_1 |
| flow_label_type | NO_LABEL |
| static_dns_records[1] | |
| fqdn[1] | ggg.avi.local |
| type | DNS_RECORD_A |
| ip_address[1] | |
| ip_address | 1.1.1.1 |
+----------------------------------+-----------------------------------------------------+Another similar custom A record can be added:
: virtualservice< static_dns_records
New object being created
: virtualservice:static_dns_records< fqdn abc.avi.local
: virtualservice:static_dns_records< ip_address
New object being created
: virtualservice:static_dns_records:ip_address< ip_address 11.11.11.11
: virtualservice:static_dns_records:ip_address< save
: virtualservice:static_dns_records< type dns_record_a
: virtualservice:static_dns_records< save
: virtualservice< save

+----------------------------------+-----------------------------------------------------+The above command sequence will create a static entry for the FQDN abc.avi.local on virtual service dns-vs. This can also be confirmed from the GUI under Applications -< Virtual Services -< DNS Records, as illustrated below.
