10.1.34.4 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 : .......................................... Experimental results: When we select a DIS , DIS represents the broadcast network, including all ISs connected to the broadcast network. ! 1bit is the bottom of the stack (this position is 1 , the last label. You can press a multi-layer label on a data packet, and the Bos bit of the last label is set to 1. When processing to this layer, the upper-layer data packet is normal data. package.) In IOS , the normal router hello interval defaults to 10S ,schedule ccna exam, and the DIS defaults to 3.3S . 5.5.5.5 Mpls traffic-eng tunnels ip rsvp bandwidth i L1 10.1.34.0 [115/20] via 10.1.123.3, FastEthernet0/0 C 10.1.123.0 is directly connected, FastEthernet0/0 i* L1 0.0.0.0/0 [115/10] via 10.1.123.3, FastEthernet0/0 The configuration of R1 is as follows (other basic configurations are omitted directly): Signalling: connected 0/0/0 3bit experimental bits for QoS Interface fas1/0 DIS Local binding: tag: imp-null 0x9540 Interface eth0 1/0 Src 1.1.1.1, Dst 4.4.4.4, Tun_Id 0, Tun_Instance 39 RSVP Path Info: Router(config)#interface fast0/0 Meet the FIB , LIB , and LFIB tables Activate the MPLS TE extension for each router's OSPF and manually set the RouterID for MPLS TE . 0180-C200-0015 LDP session protection Next-address 10.1.24.4 2.2.2.2/32 Interface tunnel0 Interface Tunnel0 *Aug 18 04:37:06.239: Router ospf 1 Tib entry: 4.4.4.4/32, rev 14 Kbps (Global) Priority: 7 7 Affinity: 0x0/0xFFFF A label switched path (LSP) OSP PDU 55.55.55.55 and 5.5.5.5 will no longer take the tunnel .

When I receive the remote binding from the LDP neighbor , I bundle the tags and the local bindings that are localized for the specific prefix into the LIB .

Indicates the available status of a router resource. If the bit is set, it indicates that the router is overloaded. Overloading means that the performance of the router is suppressed due to insufficient CPU and memory resources. It was set overload field that LSP does not diffuse in the network and is calculated by the overload routing the router will not use the LSP .
