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
