Creating virtual servers to load balance zone transfer requests to a pool of DNS servers
Determine to which DNS servers you want the virtual servers to load balance DNS zone
transfer requests.
Create virtual servers to alert the BIG-IP system to zone transfer requests destined
for a pool of DNS servers that host the zone. Create two virtual servers that use
the TCP protocol, one each for an IPv4 address and IPv6 address.
DNS zone
transfers use TCP port
53
. This task applies only to LTM-provisioned
systems.
- On the Main tab, click .The Virtual Server List screen opens.
- Click theCreatebutton.The New Virtual Server screen opens.
- In theNamefield, type a unique name for the virtual server.
- In theDestination Address/Maskfield, type the IP address in CIDR format.The supported format is address/prefix, where the prefix length is in bits. For example, an IPv4 address/prefix is10.0.0.1or10.0.0.0/24, and an IPv6 address/prefix isffe1::0020/64or2001:ed8:77b5:2:10:10:100:42/64. When you use an IPv4 address without specifying a prefix, the BIG-IP system automatically uses a/32prefix.The IP address for this field needs to be on the same subnet as the external self-IP.
- In theService Portfield, type53.
- From theProtocollist, selectUDP.
- Optional: If you are using SNATs on your network, from theSource Address Translationlist, selectSNAT.
- Optional: From theSNAT poollist, select the name of an existing SNAT pool.
- From theConfigurationlist, selectAdvanced.
- From theDNS Profilelist, select the custom DNS profile you created.
- ClickFinished.
Create another virtual server with the
TCP protocol, but use an IPv6 address and configuration.
