MPLS Label Switching
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:
http://www.cisco.com/en/US/docs/ios/12_2t/12_2t13/feature/guide/ftiasl13.html
MPLS VPN Hot Standby Router Protocol (HSRP) Support—This feature ensures that the HSRP
•
virtual IP address is added to the correct IP routing table and not to the global routing table. See this
publication:
http://www.cisco.com/en/US/docs/ios/12_1t/12_1t3/feature/guide/dt_hsmp.html
OSPF Sham-Link Support for MPLS VPN—This feature allows you to use a sham-link to connect
•
VPN client sites that run the Open Shortest Path First (OSPF) protocol and share OSPF links in a
MPLS VPN configuration. See this publication:
http://www.cisco.com/en/US/docs/ios/12_2t/12_2t8/feature/guide/ospfshmk.html
Any Transport over MPLS (AToM)—Transports Layer 2 packets over an MPLS backbone. See the
•
"Any Transport over MPLS" section on page
