0 kbits/sec In the forwarding process, a set of data with the same processing mode can be identified by means of address, tunnel, COS, etc., usually in one set.

After all, the performance of the device is getting better and better. Mpls label rangempls label range 400 499 interface fa0/0 O In a Frame Relay network, SNPA is DLCI Note that LDP does not assign labels to BGP routes by default ,free cisco practice exams, but we also know that BGP routes have next-hop , and this next hop is reachable for IGP routes, and LDP will be this (next hop) It is very important that the address is assigned to the route assignment label. The interface of each router activates RSVP and MPLS TE tunnel support. 0/0/0 0/0/0 Interface fas0/0 LDP non-directly connected neighbors 0xA538 Targeted Hello 1.1.1.1 -> 3.3.3.3, active, passive 4 is IPv4 . If it is 6 or IPv6 , the LSR uses this value to determine whether the message is V4 or V6 , and then selects a complex equalization algorithm according to different IP versions. Reservable Bandwidth[6]: OSPF Extended intermediate system reachability TLV (type 22 ) Regarding the priority of the tunnel and the verification of the currently available bandwidth: First , the configuration of the tunnel is as follows: State: Oper; Msgs sent/rcvd: 13/13; Downstream Up time: 00:03:47 Tunnel mpls traffic-eng forwarding-adjacency So using this feature (an IS-IS process to configure multiple NET addresses), you can achieve: The default LDP label space is platform-based per-platform or device-based. What do you mean? Let's look at the B router, which bundles the label 34 for the prefix X , and publishes the label binding information to all LDP neighbors, which is the same for everyone, and everyone has a label 34 . This is based on the platform. Then there is an interface-based tag space. Modify target ldp session related parameters Type escape sequence to abort. Tracing the route to 4.4.4.4 We know that IS-IS actually recognizes two types of networks, one is peer-to-peer and the other is broadcast multi-access network. For NBMA , such as frame relay networks, IS-IS deployment should be cautious, to see what will be wrong: Ip cef / / Whether the local will retain all the label mapping messages received from the neighbor in the database System LDP autoconfig Can use the default or use this command to modify Router(config-if)# bandwidth ? Router ospf 1 The principle is similar to the plaintext interface authentication, but can be given HMAC-MD5 certification. Ip address 3.3.3.3 255.255.255.255 Configured in OSPF process mode, this command activates MPLS TE in a specific area.

Integrated IS-IS is a routing protocol that can handle multiple network layer protocols (such as IP and CLNP ) simultaneously . In contrast, OSPF only supports one network layer protocol of IP , that is, OSPF only supports IP routing. The integrated IS-IS can support pure CLNP network or pure IP network, or support both CLNP and IP network environments and provide routing functions. After years of development, the integrated IS-IS protocol has become a scalable, powerful and easy-to-use IGP routing protocol, and has been used in carrier networks for more applications and deployments.
