Redirecting DNS Queries Using a CNAME Pool
Overview: Redirecting DNS queries using a CNAME pool
Creating a CNAME pool
- On the Main tab, click.The Pool List screen opens.
- ClickCreate.The New Pool screen opens.
- In theNamefield, type a name for the pool.Names must begin with a letter, and can contain only letters, numbers, and the underscore (_) character.The pool name is limited to 63 characters.
- From theTypelist, select theCNAMEtype.
- In the Members area, for theMember Listsetting, from theWide IPlist, select either a pool member (A or AAAA type) or a static target, and then clickAdd.
Creating a wide IP with a CNAME pool
- On the Main tab, click.The Wide IP List screen opens.
- In theNamefield, type a name for the wide IP.You can use two different wildcard characters in the wide IP name: asterisk (*) to represent several characters and question mark (?) to represent a single character. This reduces the number of aliases you have to add to the configuration.
- From theTypelist, select a record type to serve from the required DNS query types.If you want the BIG-IPDNS to respond to both A and CNAME record type requests, you must configure two wide IPs. One wide IP of type A with a CNAME pool type, and a second wide IP of type CNAME with a CNAME pool type. At a minimum, an A record type wide IP should be configured with a CNAME pool.
- In the Pools area, for thePool Listsetting, from thePoollist, select the name of the CNAME pool, and then clickAdd.
Viewing statistics for wide IP CNAME resolutions
- On the Main tab, click.The Global Traffic statistics screen opens.
- From theStatistics Typelist, selectWide IPs.Information displays about the cumulative number of DNS name resolution requests processed by the wide IP, and the number of requests load balanced using specific methods.
