Command or Action Purpose
Step 1

Example:
Router(config)# policy-map type service
service1
Creates or modifies a service policy map, which is used to
define an ISG service, and enters service policy-map
configuration mode.
Step 4
ip vrf forwarding name-of-vrf
Example:
Router(config-service-policymap)# ip vrf
forwarding vrf2
Associates the service with a VRF.
Step 5
sg-service-type primary
Example:
Router(config-service-policymap)#
sg-service-type primary
Defines the service as a primary service.
• A primary service is a service that contains a
network-forwarding policy. A primary service must be
defined as a primary service by using the
sg-service-type primary command. Any service that is
not a primary service is defined as a secondary service
by default.
Step 6
sg-service-group service-group-name
Example:
Router(config-service-policymap)#
sg-service-group group1

service group includes one primary service and one or
more secondary services.
