75000 Mpls traffic-eng router-id loopback0 mpls traffic-eng area 0 ! Turn off TTL propagation 1.1.1.0 is directly connected, Loopback0 2.0.0.0/24 is subnetted, 1 subnets Tunnel mode mpls traffic-eng Interface eth0/1 R1_t0 Mpls traffic-eng tunnels ip rsvp bandwidth Mpls traffic-eng tunnels ip rsvp bandwidth 0 kbits/sec If this time is specified as 0 , the periodic reoptimize will be turned off in all TE tunnels on the router . Of course,cisco ccna exam questions and answers, you can turn off reoptimize for a single TE tunnel , the command is as follows: LSP TLV field of Level 1 route Ip address 10.1.45.4 255.255.255.0 Tunnel destination 5.5.5.5 Ip address 3.3.3.3 255.255.255.255 ! Router bgp 2345 Each transport layer entity is assigned an NSAP address. The NSAP address is the network layer address of the CLNS packet . It is used to identify the device. It consists of an initial domain part ( IDP ) and a domain-defined part ( DSP ). These two parts are detailed below, let us understand this. 2 Ip route 5.5.5.5 255.255.255.255 Tunnel0 Affinity: 0x00000000 (Tunnel0) Destination: 5.5.5.5 If the link flaps, the LDP session will be re-established, and the label bundle must be exchanged again . It is very inefficient to rebuild the LDP session. We can protect the session and implement LDP session between the two directly connected LSRs . After the protection, a destination-based LDP session is established between the two LSRs , that is, the target LDP session . When the direct link between the two LSRs is DOWN , as long as there exists between the two LSRs .
