Vlan Features; Vpn And Layer 2 Tunneling Features - Cisco uBR10012 Software Configuration Manual

Supported Software Features for the Cisco uBR10012 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
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.

Generic Routing Encapsulation (GRE) Tunneling on the Cisco uBR10012
Cisco IOS Release 12.3(17a)BC introduces Generic Routing Encapsulation (GRE) Tunneling on the
Cisco uBR10012.
Generic Route Encapsulation (GRE) is a tunneling protocol that can encapsulate a variety of packet types
inside IP tunnels, creating a virtual point-to-point link to Cisco routers at remote points over an IP
internetwork.
