The Cisco ISG – PTA
When we implement PPPoE using a
multi-VRF setup it appears that the COA client needs to be on the same VRF as
the client it is referencing by the SSG-Account-Info, usually this is the
clients IP address.
Diagram 1.
Virtual-Template Configuration:
The loopback and virtual-template interfaces are on the
INTERNET VRF.
COA Server Configuration:
Now when I try to send a COA request to activate a service:
You can see that we are getting a COA Nack.
The way to resolve this is to enable the NAS to send the VSA
on the accounting requests and use the “parent-session-id” as your reference.
With the above we can see that the service has been
activated.
