It is required to complete the following task on both dns.sitea and dns.siteb
Navigate to: DNS ›› Delivery : Listeners : Listener List
Create a TCP listener according to the following table:
| Setting | dns.sitea | dns.siteb |
|---|---|---|
| Name | dns_sitea_ns1.f5demo.com_tcp_53_virtual | dns_siteb_ns2.f5demo.com_tcp_53_virtual |
| Destination | 10.1.10.101 | 10.1.60.101 |
| Protocol Profile (Client) | f5demo.com_tcp-dns_profile | f5demo.com_tcp-dns_profile |
| DNS Profile | f5demo.com_dns_profile | f5demo.com_dns_profile |
dns.sitea TMSH command:
TMSH
tmsh create gtm listener dns_sitea_ns1.example.com_tcp_53_virtual address 10.1.10.101 ip-protocol tcp mask 255.255.255.255 port 53 profiles add { f5demo.com_dns_profile f5demo.com_tcp-dns_profile }
dns.siteb TMSH command:
TMSH
tmsh create gtm listener dns_siteb_ns2.example.com_tcp_53_virtual address 10.1.60.101 ip-protocol tcp mask 255.255.255.255 port 53 profiles add { f5demo.com_dns_profile f5demo.com_tcp-dns_profile }
