Cisco ASR 9000 Series Router Overview
2 Tunnel Protocol access concentrator (LAC) from the RADIUS server. For more information on
radius-based lawful Intercept, see the Cisco ASR 9000 Series Aggregation Services Router
Broadband Network Gateway Configuration Guide.
HTTP Redirect (HTTPR) IPv6—This feature is implemented using the Policy Based Routing (PBR)
•
functionality that allows creating packet forwarding decisions based on the policy confiration
instead of routing protocols. The HTTPR is supported for both IPoE and PPPoE subscribers. For
more information on HTTPR support, see the Cisco ASR 9000 Series Aggregation Services Router
Broadband Network Gateway Configuration Guide.
ACL (Access Control List) IPv6—This feature is used for filtering content, blocking access to
•
various network resources, and specifying in the ACL configuration the next-hop address, which is
then used to route certain traffic through specific paths instead of using the path computed by routing
protocols. For more information on ACL Ipv6, see the Cisco ASR 9000 Series Aggregation Services
Router Broadband Network Gateway Configuration Guide.
TCP MSS Adjustment—This feature allows for the configuration of the maximum segment size
•
(MSS) on transient packets that traverse a Cisco ASR 9000 Series Router. For more information on
TCP MSS, see the Cisco ASR 9000 Series Aggregation Services Router Broadband Network
Gateway Configuration Guide.
• QoS - Shared Policy Instance— This feature allows allocation of a single set of QoS resources
among groups of sub-interfacesand bundle sub-interfaces, and shares them across a group of
sub-interfaces, multiple Ethernet flow points (EEPs), or bundle interfaces. For more information onf
Share Policy Instance, see the Cisco ASR 9000 Series Aggregation Services Router Broadband
Network Gateway Configuration Guide.
Dual Stack over PPPoE and IPoE—This feature is supported on both IPoE and PPPoE subscribers.
•
In the case of PPPoE, the same subscriber session has both IPCP and IPv6CP running over the
PPPoE sessions. In case of IPoE, DHCP would start the subscriber session on first-sign-of-life
(FSOL) and assign IP address to the subscriber. For more information on Dual Stack, see the Cisco
ASR 9000 Series Aggregation Services Router Broadband Network Gateway Configuration Guide.
IPv6 uRPF for IPoE and PTA—This feature ensures that the source IP address is the one allocated
•
by DHCP to the source MAC address for IPoE subcribers. For PPP over Ethernet (PPPoE) PPPoE
subscribers, the uRPF ensures that the source address in the arriving packet match the set of
addresses associated with the subscriber. The uRPF is supported on both IPv4 and IPv6 subscribers
and is enabled using dynamic template. For more information, see the Cisco ASR 9000 Series
Aggregation Services Router Broadband Network Gateway Configuration Guide.
• IPv6 over PPPoE and IPoE Sessions—This feature enables processing of IPv4 or IPv6 protocol on
an access interface and IPoE subscriber creation on access interface by activating service-policy.
The PPP over Ethernet (PPPoE) session is established with the subscriber over an ethernet network,
so that the standard PPP negotiations is for authentication and IPv4 or IPv6 address assignment. For
more information, see the Cisco ASR 9000 Series Aggregation Services Router Broadband Network
Gateway Configuration Guide.
• Distributed address pool service (DAPS) Support—This feature allows address pools to be shared
between DHCP processes that run on the line card or route processor. For more information on DAPS,
see the Cisco ASR 9000 Series Aggregation Services Router Broadband Network Gateway
Configuration Guide.
BNG on Satellite—This feature allows BNG to exchange and use information with other larger
•
heterogeneous networks. For more information on BNG on Satellite, see the Cisco ASR 9000 Series
Aggregation Services Router Broadband Network Gateway Configuration Guide.
