ccna and ccnp

We see that on R1 , the outgoing label of the relevant route prefix is untagged . The R1 's routing table temporarily without any change. In this environment now,ccna and ccnp, although R1 still be able to ping through 3.3.3.3 , but in fact has a problem, because it is a direct walk IPv4 packets, rather than the package label. R1.00-00 Basic Experiment 2 ( IS-IS ) ---------- 0 The boundary of the area is on the router Was used to replace TLV128 . Control metric through dynamic routing protocol to affect routing routing All routers in the LAN including the DIS establish an adjacency relationship with the PSN , relying on the adjacent relationship formed by the pseudo node on the LAN . Once the DIS generates a pseudo node in the LAN , the reliability is guaranteed. It periodically sends a first one layer and two layers Hello PDU and the CSNP . The Hello PDU indicates that it is a layer of DIS . The CSNP describes the summary information of all LSPs , including LSP ID , sequence number, checksum, and remaining lifetime. It uses multicast to flood. CSNP is only used to correct any missing PDUs .
