IES Features
Routing Protocols
The IES IP interfaces are restricted as to the routing protocols that can be defined on the interface
based on the fact that the customer has a different routing domain for this service. The IES IP
interfaces support the following routing protocols:
•
•
•
•
•
•
Note that the SAP for the IES IP interface is created at the IES service level, but the routing
protocols for the IES IP interface are configured at the routing protocol level for the main router
instance.
QoS Policies
When applied to 7750 SR IES services, service ingress QoS policies only create the unicast queues
defined in the policy. The multipoint queues are not created on the service.
With IES services, service egress QoS policies function as with other services where the class-
based queues are created as defined in the policy.
Note that both L2 or L3 criteria can be used in the QoS policies for traffic classification in an IES.
Filter Policies
Only IP filter policies can be applied to IES services.
