However, since R2 does not enable authentication,ccna classroom training, the LSPs sent by R1 are sent to R2 . R2 ignores the authentication information in the LSP and directly reads the LSP . Therefore, R2 can learn the route advertised by R1 . Of course, there is no R1 routing. Record Route: NONE After the configuration is complete, the level 2 LSP sent by R2 will carry the cipher text authentication TLV information (the level 1 LSP is not carried). If this configuration is maintained, we will find that R2 can only learn the R1 release. Routing, this is because level1 LSPs are not authenticated. After completing this experiment, R3 and R4 complete the configuration. PATH/RESV Average rate=250000 bytes/sec, burst depth=1000 bytes Mpls ldp router-id loopback0 mpls label protocol ldp 2.2.2.2/32 Area verification is actually the verification of Level1 area . After the area authentication is added to an IS-IS router, it will check the IS-IS packets it receives . If there is no authentication information or error in the packet, it will be ignored. The IS-IS packet generated by the device itself carries the authentication information. If the receiver does not have the configuration area authentication, the device can still learn normally after receiving the packet carrying the authentication information. The authentication information of the area authentication is only included in the LSPs packet. Other packets are not included.
