Cisco ASR 901 Series Aggregation Services Router Software Configuration Guide
OL-23826-09
Chapter
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.
