Network 10.1.45.5 0.0.0.0 area 0 The virtual link implements a level 1 repair path through the backbone . The zone designated router sets the partition repair of its level1 LSP . C . There is a small detail, noted that the distribution of the label no concept of split horizon, that although B may be from C to learn the route to X , but B still will be prefixed with X passed to the bundled label C . C will also put the label passed from B in the LIB , but don't worry about loops, because LDP can prevent loops by means of IGP routing protocol. Experimental procedure *Aug 18 11:26:02.546: OAM alarm tag Mpls traffic-eng tunnels ip rsvp bandwidth ATT/P/OL The PATH message carries a label request object, which is hopped and hopped from the tunnel first-end router to the tail router. The configuration of R2 is as follows: Mpls traffic-eng tunnels mpls label range 200 299 RFC 2973 TE tunnel is one-way Traditional TE solutions have the following examples: !

Route summarization on the L1/L2 router ( to level1 ) Test the transmission process of the data stream, observe the phenomenon Both data packets have the same format and each carry a collection of LSP summary information. The difference is that the CSNP carries summary information of all known LSPs in the link state database of the router , and the PSNP carries one of the subsets. To distinguish Level-1 , Level-2 link state database, the router generates Ll , L2 of independent SNP packets.

Therefore, if you want to make the routing full, you need to add a re-release directly to R3 . *Aug 18 09:06:07.919: Path MTU: 4294967295 Link connected to Broadcast network Link ID : 10.1.12.2 RSVP Path Info: 2.2.2.2 is directly connected, Loopback0 5.5.5.5 [110/31] via 5.5.5.5, 00:00:01, Tunnel0 10.1.12.0/24 is directly connected, Ethernet0/0 10.1.23.0/24 is directly connected, Ethernet0 /1 Ip address 10.1.12.1 255.255.255.0 .......................................... ! The load of the routing processor is low in large areas Addresses bound to peer LDP Ident: IS-IS Level-1 Link State Database: 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.
