The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Framed Route allows you to route customer additional networks (behind CPE) through customer broadband connection in ISG. Framed Route has relevance only when CPE acts as routed CPE and NAT is disabled. The broadband IPoE/PPPoE connection for CPE is created at ISG and the network behind CPE must be routed through CPE IPoE/PPPoE session in ISG. A per-user static route is downloaded to IPoE/PPP users through the Framed-Route RADIUS attribute during login.
Framed Route allows a large number of customer networks to reach via framed routes through a single ISG session.
Framed Route is supported on both IPoE and PPPoE sessions.
There is no limit enforced to the number of framed routes per session.
You don't have to configure or enable Framed Route through command line interface as it is downloaded from RADIUS.
Framed Route cannot be applied through a RADIUS COA.
No support for routed session.
Dual stack is not supported.
ISG does not expect next hop information in Framed-Route AVP. ISG will replace Next hop information with CPE IP.
If CPE already has an IP address assigned, then RADIUS server should always provide CPE IP in Framed-IP-Address AVP in Access-Accept.
There is no manual configuration required to enable Framed Route through command line interface as it is downloaded from RADIUS.
Following are samples of the framed route configuration from RADIUS:
Cleartext-Password := "cisco”
Service-Type = Framed-User,
Framed-IP-Address = 40.0.0.1,
Framed-Route += "131.1.1.0 255.255.255.0",
Cisco-AVPair += "subscriber:accounting-list=List1“Cleartext-Password := "cisco“
Service-Type = Framed-User,
Framed-Route = "131.1.2.0 255.255.255.0",
Framed-Route += „131.1.3.0/24“,
Cisco-AVPair += "subscriber:accounting-list=List2“
Use the show subscriber session command to verify the subscriber session output when Framed Route is installed:
Device# show subscriber session 1 detailed

Use the following debug commands if you have any configuration issues:
debug subscriber feature name static-routes{error | event} - Enables debugging of the static-route feature.
debug subscriber{error | event | feature} - Enables debugging of subscriber sessions.
debug ip subscriber all - Enables debugging of IP subscribers.
debug ppoe{errors | events} - Enables debugging of PPPoE subscribers.
