For example, if the Layer 2 encapsulation is Ethernet (data frame), look at the value of the Type / Length field of the frame header : The configuration of R2 is similar, so that in the TLV used for authentication in the IIH , the ciphertext after the hash is loaded, and the password is not exposed. Globally activate MPLS TE tunnel and set MPLS label space 300 Like the above figure, 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 ,ccna vce files free download, or through policy routing.
