Activate CEF DC LSP TLV field of Level 2 route 10.1.12.2 *Aug 18 09:06:07.919: ADSPEC type 2 length 48: Network Services Access Points At this time, TTL propagation can be turned off ( CISCO router is enabled by default) IP internal reachability information Delay metric is optional, the link transmission delay is not supported. 2 The link state database of TEDB and IGP is independent. Type escape sequence to abort. Tracing the route to 6.6.6.6 Ip explicit R1toR5 Network Entity Title is the last byte 0 of the NSAP , it is a device identification ( the NSAP port number is 0 thing).

The acl-peer is an association ACL used to match the LDP peer to be protected . Note that the matching ACL must be the neighbor's LDP router ID. R2#sh mpls tr link-management advertisements IP interface address Basic experiment ( NodeProtection ) Router ospf 1 IS , since this is a LAN environment, DIS is elected , and each non- DIS router advertises its own adjacency with the DIS without notifying the adjacency with other physical ISs . The LSP of R3\R3 is similar, and will not be described here. Take a look at the LSP of this pseudonode : Label or VC The target network segment involved in MPLS is the same as traditional IP forwarding. RFC 2370 describes an extension of OSPF that defines three new LSAs . These LSAs are called sluggish LSAs ( opaque LSAs ) and their differences are limited to the extent of propagation. These LSAs can accurately provide the information required by MPLS TE to OSPF : 1/0/0 5.5.5.5 Tunnel mpls traffic-eng autoroute metric absolute 9 Otherwise, the interface may be considered in MPLS-LDP Discovery Transport interface address , the Transport Address configured as Direct interface IP address. The process of exchanging LSPs by routers in an area is called flooding . The LSPs received from neighboring routers in the area are stored in the local router. The flooding and interaction of LSPs eventually form the IS-IS link state database. The above command will add or subtract z from the original cost of the route ( the range of z is -10 to 10 ) A label switched path (LSP) neighbor is a neighbor of the LDP routerID accept acl to match the prefix Record Route: Ip address 10.1.34.4 255.255.255.0 R3 configuration is as follows (Note that, Area0 and area1 must activate the MPLS the TE ): Ip address 10.1.45.4 255.255.255.0 Bw[7]: According to the protection object can be divided into: 10.1.12.2 8 msec 4 msec 0 msec We can avoid this problem by using overload-bit . The command is explained as follows (configured under the router isis process): In R2 on Global Pool BW Unreserved: 10 The router in Lan establishes an adjacency with all other routers in the same LAN with the same area ID and hierarchy . The loopback0 address of all devices is xxxx/32 , and x is the device number.

It is possible that the metric assigned by the link is not the same as the actual metric . If the LDP hold time configuration of the two LDP peers is different, the smaller one will be used as the hold time of the LDP discovery. Note that the LDP HELLO message does not carry the hello interval time and only carries the holdtime . Therefore, if different holdtimes are configured on both ends , the small value will be used as the hold time of the LDP discovery. Cisco IOS may rewrite the configured LDP Hello interval.
