Hi Reda,

I've some additional comments on your questions.

Sanjeev>> You typically store your policies in LDAP repository as they are
relatively static. PIB contents are dynamic and contains status and
configuration
information of the devices. It is a MIB that contains policy
information.

Sanjeev>> You need a proxy PEP if the devices are not COPS enabled. THe
Proxy would use SNMP or CLI for example to enforce a policy on such
devices. In one scenario, we were required to control thousands of Virtual
routers(sitting on one physical device) and since it would be expensive to
maintain thousands of TCP connections(one per Virtual router) we had a
proxy to handle that for us.
