Age ISO addressing Tunnel: Metric: 0 TE headend router tunneling according TE calculated database TE optimal path of the tunnel, and with reference to the bandwidth constraints. In addition, the optimal path can also be defined by an explicit path option that the user configures on the tunnel interface. In either case, the headend router knows the specific path used by the TE tunnel. Targeted Hello 2.2.2.2 -> 4.4.4.4, active Priority : Priority. The DIS priority of the interface used to elect the DIS in the broadcast LAN . The higher the priority value, the more likely the router becomes a DIS .

Once the DIS generates a pseudo node in the LAN , the reliability is guaranteed. It periodically sends a first one layer and two layers Hello PDU and the CSNP . The Hello PDU indicates that it is a layer of DIS . The CSNP describes the summary information of all LSPs , including LSP ID , sequence number, checksum,ccna program, and remaining lifetime. It uses multicast to flood. CSNP is only used to correct any missing PDUs .
