OL-23826-04	August 2012	Following are the updates specific to this release:
		• DHCP client on SVI—This feature allows you to configure
		DHCP client on SVI interface.
		• HSRP/VRRP—This feature allows you to configure the Hot
		Standby Router Protocol (HSRP) or Virtual Router
		Redundancy Protocol (VRRP) protocol.
		• TWAMP Responder—This feature allows you to deploy
		TWAMP in a simplified network architecture, with the
		control-client and the session-sender on one device and the
		server and the session-reflector on another device.
		• Dying Gasp—This feature allows you to send notifications
		during power failure, link down, router reload and link
		administratively down conditions.
		• Multihop BFD—This feature allows you to do subsecond
		forwarding failure detection for a destination with more than
		one hop and up to 255 hops.
		• Ethernet Loopback—This feature allows you to use per-port
		and per VLAN Ethernet loopback to test connectivity at
		initial startup, to test throughput, and to test quality of
		service in both directions.
		• LLDP—This feature allows the network devices to advertise
		information about themselves to other devices in the
		network.
		• Bit Error Rate Testing—This feature allows you to test the
		integrity of the physical layer. For more details, see Bit Error
		Rate Testing.
		• IPv6 Support—This feature supports Long Term Evolution
		(LTE) rollouts that provides high-bandwidth data connection
		for mobile wireless devices. The Cisco ASR 901 router
		supports IPv6 addressing on Switch Virtual Interface (SVI),
		Loopback, and Ethernet interfaces. For more details, see
		IPv6 Support on the Cisco ASR 901 Router.
		• Labeled BGP Support—This feature describes how to add
		label mapping information to the Border Gateway Protocol
		(BGP) message that is used to distribute the route on the
		Cisco ASR 901 Series Aggregation Services Routers. For
		more details, see Labeled BGP Support.
		• MPLS Traffic Engineering—This feature describes the Fast
		Reroute (FRR) link protection and Bidirectional Forwarding
		Detection (BFD)-triggered FRR feature of Multiprotocol
		Label Switching (MPLS) traffic engineering (TE). The
		MPLS TE is supported on the Cisco ASR 901 router to
		enable only the FRR. The traffic engineering aspects of
		MPLS TE is currently not supported. For more details, see
		MPLS Traffic Engineering - Fast Reroute Link Protection.
