●
BFD multihop: In a BFD multihop session, BFD control packets on IPv4 are used to confirm whether the
remote peer is alive. BFD multihop also detects interruptions of the forwarding path between two BFD peers
based on the detection time used for a BFD multihop session.
based on the detection time used for a BFD multihop session.
●
UDLD: UDLD is a Layer 2 protocol that works with the Layer 1 mechanisms to determine the physical status
of a link. UDLD performs tasks such as detecting the identities of neighbors, detecting unidirectional
connectivity faults, and shutting misconnected ports.
connectivity faults, and shutting misconnected ports.
●
Local Connect Redundancy: Cisco ASR 9000 resiliency support is further enhanced by Local Connect
Redundancy. The feature allows the specification of a backup Ethernet Flow Point (EFP) for an EFP with
local connection. This supports dual-homing EFPs with connectivity local to the router.
local connection. This supports dual-homing EFPs with connectivity local to the router.
●
OSPFv3 Non-stop Routing (NSR): OSPFv3 NSR provides the ability to perform hitless switchovers when
OSPF is used as a routing protocol without the need for neighboring routers to be NSR capable
●
Hot Standby Router Protocol (HSRP) Multiple Group Optimization (MGO): HSRP MGO provides the ability to
create client HSRP groups that follow the status of the master HSRP group. This helps reduce the control
traffic and boost the system HSRP scalability.
traffic and boost the system HSRP scalability.
Carrier Grade NAT (CGN)
The CGN solution helps supplement the IPv4 address space while maintaining the same services that people
are used to today. This solution uses the carrier-class Cisco IOS XR control plane, the purpose-built hardware-
based forwarding Ethernet line cards and the Integrated Services Module (ISM) for NAT444 translation setup.
This stateful NAT444 solution is also equipped with an extremely scalable and innovative NetFlow logging
system to facilitate historical tracking of private to public translations. CGN is a licensed feature that can be
activated with the purchase of the A9K-CGN-LIC-5M software license.

●
Selective VRF Download (SVD): SVD is a solution used to download only those prefixes and labels to a line
card that are actively required to forward traffic through that line card. SVD reduces scalability and
convergence problems in L3VPNs by enabling selective download of a VRF routes to only those line cards
which are configured with that VRF.

●
QPPB: QPPB helps to classify packets by QoS Group ID, based on access control lists (ACLs), Border
Gateway Protocol (BGP) community lists, BGP autonomous system (AS) paths, Source Prefix address, or
Destination Prefix address. After packet classification, other QoS features such as policing and weighted
random early detection (WRED) can be used to specify and enforce policies to fit a specific business model.

●
PoS link bundling on Cisco ASR 900 SIP-700 line card: Link bundling is used to group multiple point-to-point
links together into one logical link to provide higher bidirectional bandwidth, redundancy, and load balancing
between two routers. The Cisco ASR 9000 Series routers support bundling for PoS interfaces on the ASR
9000 SIP-700 line card. The line card can physically accommodate up to 32 PoS link bundles provided that
all of them have the same speed.

●
IPv4 unicast Generic Routing Encapsulation (GRE) on Cisco SIP-700: GRE is a tunneling protocol used to
encapsulate many types of packets to enable data transmission using a tunnel. IPv4 unicast GRE is now
supported on the Cisco ASR 9000 SIP-700.

●
ACL Based Forwarding (ABF) v6 and v4/v6 VRF aware: ABF provides an alternative to regular routing by
providing the ability to forward to a next hop, based on packet content that extends beyond the destination IP
address.. Cisco IOS XR 4.2.0 release enables ABF support for v6 and ABF support on VRF interface for
both v4 and v6

●
BGP multi-AS per Address Family (AF): Multi-AS BGP allows each instance of a multi instance BGP to be
configured with a different AS number. It offers the following benefits: consolidates the services provided by
multiple routers using a common routing infrastructure into a single IOS-XR router; provides a mechanism to
achieve AF isolation by configuring the different AFs in different BGP instances; provides a means to achieve
higher session scale by distributing the overall peering sessions between multiple instances

Video features
●
Vidmon unicast: New hardware line cards will support video monitoring functionality for unicast flows. Full
backward compatibility with the multicast features (including Trap and Clone) will be maintained. Unicast
flows will be supported with SPAN configuration with the limitations similar to L3 SPAN from bandwidth and
TM usage perspective.
