PFC3BXL and PFC3B Mode MPLS Label Switching
•
MPLS TE—MPLS traffic engineering software enables an MPLS backbone to replicate and expand
upon the traffic engineering capabilities of Layer 2 ATM and Frame Relay networks. MPLS traffic
engineering thereby makes traditional Layer 2 features available to Layer 3 traffic flows. For more
information, see these publications:

MPLS TE DiffServ Aware (DS-TE)—This feature provides extensions made to MPLS TE to make
•
it DiffServ aware, allowing constraint-based routing of guaranteed traffic. See this publication:
http://www.cisco.com/en/US/docs/ios/12_2s/feature/guide/fsdserv3.html
MPLS TE Forwarding Adjacency—This feature allows a network administrator to handle a traffic
•
engineering, label-switched path (LSP) tunnel as a link in an Interior Gateway Protocol (IGP)
network based on the Shortest Path First (SPF) algorithm. For information on forwarding adjacency
with Intermediate System-to-Intermediate System (IS-IS) routing, see this publication:
http://www.cisco.com/en/US/docs/ios/12_2s/feature/guide/fstefa_3.html
•
MPLS TE Interarea Tunnels—This feature allows the router to establish MPLS TE tunnels that span
multiple Interior Gateway Protocol (IGP) areas and levels, removing the restriction that had required
the tunnel head-end and tail-end routers to be in the same area. See this publication:
http://www.cisco.com/en/US/docs/ios/12_2s/feature/guide/fsiarea3.html
MPLS virtual private networks (VPNs)—This feature allows you to deploy scalable IPv4 Layer 3
•
VPN backbone services over a Cisco IOS network. See this publication:
http://www.cisco.com/en/US/docs/ios/12_0st/12_0st21/feature/guide/fs_vpn.html
MPLS VPN Carrier Supporting Carrier (CSC)—This feature enables one MPLS VPN-based service
•
provider to allow other service providers to use a segment of its backbone network. See this
publication:
http://www.cisco.com/en/US/docs/ios/12_2t/12_2t8/feature/guide/ftcsc8.html
MPLS VPN Carrier Supporting Carrier IPv4 BGP Label Distribution—This feature allows you to
•
configure your CSC network to enable Border Gateway Protocol (BGP) to transport routes and
MPLS labels between the backbone carrier provider edge (PE) routers and the customer carrier
customer edge (CE) routers. See this publication:
http://www.cisco.com/en/US/docs/ios/12_2t/12_2t13/feature/guide/ftcscl13.html
•
MPLS VPN Interautonomous System (InterAS) Support —This feature allows an MPLS VPN to
span service providers and autonomous systems. See this publication:
http://www.cisco.com/en/US/docs/ios/12_0s/feature/guide/fsias24.html
•
MPLS VPN Inter-AS IPv4 BGP label distribution—This feature enables you to set up a VPN service
provider network so that the autonomous system boundary routers (ASBRs) exchange IPv4 routes
with MPLS labels of the PE routers. See this publication:
