Chapter1 Overview of CiscouBR10012 Universal Broadband Router Software

Supported Software Features for the CiscouBR10012 Router

VLAN Features

Cisco IOS IEEE 802.1Q provides support for IEEE 802.1Q encapsulation for Virtual LANs (VLANs).

VLANs can be implemented with Cisco IOS platforms in environments where the IEEE 802.1Q

encapsulation standard is required. With the introduction of the Cisco IOS IEEE 802.1Q Support feature,

Cisco IOS supported 802.1Q VLAN encapsulation, in addition to the currently supported ISL and IEEE

802.10 SDE encapsulations.

Release 12.2(11)CY adds 802.1Q VLAN support for the Cisco uBR10012 universal broadband router.

Service providers can use 802.1Q VLANs on Gigabit Ethernet interfaces to provide isolation between

different content providers' traffic. 802.1Q VLANs may be mapped to MPLS VPN, maintaining traffic

separation across an MPLS infrastructure.

VPN and Layer 2 Tunneling Features

The Cisco uBR10012 router supports multiple features and functions for virtual private networks

(VPNs), to include the following:

•Dynamic SID/VRF Mapping Support

•Generic Routing Encapsulation (GRE) Tunneling on the Cisco uBR10012

•IPv6 over L2VPN

•MPLS-VPN Network Support

•NetFlow Accounting Versions 5 and 8 Support

•Transparent LAN Service (TLS) on the Cisco uBR10012 Router with IEEE 802.1Q

•Transparent LAN Service and Layer 2 Virtual Private Networks

Cisco IOS release 12.3(13a)BC introduces support for dynamic service ID (SID) and VRF mapping on

the Cisco CMTS, to support VoIP with MPLS. Formerly, the MPLS SID mapping feature only applied

to provisioned service flows. This feature enables the mapping of all PacketCable DQoS service flows

to one particular VRF.
