In the standard SPF algorithm, there can be multiple equivalent paths to the same destination. We call it ECMP ( Equal-cost Multipath ). R1#show mpls traffic-eng tunnels 0/0/0 Reservable Bandwidth[1]: 10.1.12.2 Initial database synchronization is performed after the adjacency is established. InLabel : - After the above configuration is completed, there is one more unidirectional direct link to R5 on R2 . This link will directly participate in the routing calculation of R2 itself. The overall result is that there are now three straight connectors on R2 : eth0/0 , eth0/1 , tunnel0 . Brief introduction to the work process Local binding: tag: imp-null Fa0/0 55.55.55.55 [110/2] via 0.0.0.0, 00:00:01, Tunnel0 PDUtype : PDU type. This is a 5- bit field that identifies the type of IS-IS packet. A value of 15 indicates L1 LAN IIH ; a value of 16 indicates L2 LAN IIH ; a value of 18 indicates L1 LSP ; a value of 20 indicates L2 LSP ; a value of 24 indicates L1 CSNP ; a value of 25 indicates L2 CSNP ; a value of 26 indicates L1 PSNP A value of 27 indicates L2 CSNP . Router(config-if)#tunnel mpls traffic-eng priority establish priority hold priority *Aug 18 11:31:44.598: Like the above figure,ccna code 2015, it is very easy for traffic to go unilaterally. The R1-R3-R4-R5 link does not carry traffic. It may be possible to adjust the link such as cost to make the following link available. The method may bring problems to other traffic while adjusting. In general, the IP traffic engineering guides the traffic to a relatively simple one. It is nothing more than the ospf protocol that manipulates the cost by using the characteristics of the protocol itself, or manipulates the path attributes like BGP , or through policy routing.
