0x80000018 0x001C01 1 Then we wait for the BGP neighbor relationship on R2 to be established. You can debug it: Configuration command Address, see what the next IP address is, and then send the PATH message to the next hop. This behavior continues backwards until the Create a tunnel Then the LSR pushes the IP packet into a tag header, tags 204 , and forwards it out from the F0/0 interface. In CISCO IOS , CEF switching is the only IP forwarding mode that can be used to mark messages . Therefore ,ccna actual exam, CEF must be enabled on the router when MPLS is enabled . Interface loopback0 Interface Modify the bandwidth UP/DOWN threshold The target network segment involved in MPLS is the same as traditional IP forwarding. Configure this hidden command on the penultimate hop router (that is, R2 in the figure above ): Router ospf 1 After the configuration is complete, we find that the adjacency relationship between R1 and R2 is UP , that is, the area authentication does not carry the authentication information in the IIH packet. Not only that, but the PSNP sent by R1 also has no authentication information, but the issued LSP has clear text authentication information. The experimental phenomenon is quite interesting. For R1 , all IS-IS messages received by R2 are not authenticated. R1 mainly focuses on LSP . It is found that the LSP sent by R2 has no TLV for authentication , so R1 ignores The LSP sent by R2 causes the routing table of R1 to be empty. However, although the LSPs sent by R1 are all with authentication information, R2 is not enabled.Area authentication, so R2 receives this packet, can also read, and can also use these LSPs , so R2 can learn the route of R1 .
