Using Domain Name Aliases

Example 1
62
You can translate an original domain name to a new domain name via the translate
command. The command allows you to create domain name aliases; that is, the grouping
of multiple domain names into a single domain name. You can partition PPP subscribers
with the same domain into separate domains, based on the PPP interface.
NOTE: Partitioning subscribers does not cause modification of a user's name or domain.
When you use aliases, you greatly simplify the configuration process. When there are a
large number of domains and you use aliases, it reduces the configuration volume, thus
requiring less NVS and memory usage.
In this example, an administrator wants to associate all subscribers of a PPP interface
with a specific domain name.
Create an AAA profile.
1.
host1(config)#aaa profile forwardToXyz
Map the original domain name to the mapped domain name for domain map lookup.
2.
host1(config-aaa-profile)#translate default xyz.com
Associate the AAA profile with the designated PPP interface.
3.
host1(config-if)#ppp aaa-profile forwardToXyz
When configured as such, the following scenario is typical:
PPP passes the AAA profile forwardToXyz to AAA in the authentication request.
AAA performs the following tasks:
Receives the authentication request from PPP with the subscriber's name
morris@abc.com.
Parses the domain name abc.com and examines the specified AAA profile
forwardToXyz.
Determines that the AAA profile forwardToXyz is valid.
Searches forwardToXyz for a match on the PPP subscriber's domain name and
finds no match.
Searches forwardToXyz for a match on the domain name default.
Finds a match and continues as normal using the domain name xyz.com.
