MPLS Traffic Engineering (MPLS-TE) learns the topology and resources available in a network and then maps traffic flows to particular paths based on resource requirements and network resources such as bandwidth. MPLS TE builds a unidirectional tunnel from a source to ...

MPLS Fast Reroute (FRR) is a fast recovery local protection technique that protects TE LSPs from link, shared risk link group (SRLG), and node failure. One or more TE LSPs (called backup LSPs) are preestablished to protect against the failure of a link, node, or SRLG. If there is a ...
信息发布:MPLS流量工程使用扩展的IGP-TE来向外通告和获取网络拓扑状态信息,并形成链路状态数据库LSDB和流量工程数据库TEDB,其中LSDB用于传统的SPF计算,而TEDB用于建立TE隧道时进行选路的计算。这里的信息发布组件就是IGP-TE,IGP-TE是在普通IGP的基础之上扩展了对第10类lsa的支持,即opaque-lsa,opaque-lsa可以表征最大...

The configuration roadmap is as follows: Configure an IP address for each interface, and configure IS-IS on each node to ensure there are reachable routes between them. Enable MPLS, MPLS TE, and SR globally on each node and enable MPLS and MPLS TE on each interface to establish an SR-MP...
Static CRLSPs feature simple configuration, but they cannot automatically adapt to network changes. For more information about static CRLSPs, see "Configuring a static CRLSP." Dynamic CRLSP establishment Dynamic CRLSPs are dynamically established as follows: 1. An IGP advertises TE attributes for ...
