DNS Server Configuration Example

To configure DNS-based SSM mapping, you need to create a DNS server zone or add records to an existing

zone. If the routers that are using DNS-based SSM mapping are also using DNS for other purposes besides

SSM mapping, you should use a normally-configured DNS server. If DNS-based SSM mapping is the only

DNS implementation being used on the router, you can configure a fake DNS setup with an empty root zone,

or a root zone that points back to itself.

The following example shows how to create a zone and import the zone data using Network Registrar:

Router> zone 1.1.232.ssm-map.cisco.com. create primary file=named.ssm-map

100 Ok

Router> dns reload

100 Ok

The following example shows how to import the zone files from a named.conf file for BIND 8:

Router> ::import named.conf /etc/named.conf

Router> dns reload

100 Ok:

Network Registrar version 8.0 and later support import BIND 8 format definitions.Note
