*Aug 18 04:37:06.239: Error Node: 10.1.12.2 Ok, now let's analyze, when R1 wants to send data to R4 's Loopback 4.4.4.4 , how the data is transmitted. First analyze the control level: Periodically send CSNPs every 10S in the broadcast subnet to flood LSPs Router-id 1.1.1.1 Primary lsp path: 10.1.12.1 10.1.12.2 The above label, there is another way to see, is to look at the TE Tunnel directly on R2 : Default metric is supported by all IS-IS routers and is often interpreted as a measure that is inversely proportional to bandwidth. Then from the tunnel0 port, cost=1+1=2 , better, so the routing table of R2 changes: Connection TCP: 2.2.2.2.31044 - 1.1.1.1.646 , indicates that the LDP connection is built on TCP 's 1.1.1.1 source port 646 , to the destination 2.2.2.2 of 31044 ports. Because the 2.2.2.2 address is large, it is the initiator. AutoBandwidth IS-IS and ES-IS do not place routing information in IP or CLNP packets, but directly in the data link layer Frame (so that packaging is more efficient). *Aug 18 04:37:06.239: Incoming PathError: !!R2 sends a patherror message to R1 Network 10.1.45.4 0.0.0.0 area 0 O 10.1.34.0 [110/3] via 10.1.12.2, 00:00:39, FastEthernet0/0 ! *Aug 18 09:06:07.919: SENDER_TEMPLATE type 7 length 12: Router-id 2.2.2.2 Tunnel mpls traffic-eng path-option 10 dynamic Usually LDP sessions are established between directly connected LSRs , but in some cases, a remote, or destination-based LDP session,latest ccna exam version, such as a TE tunnel in an MPLS VPN , may be required . When a link flapping occurs, a destination-based LDP neighbor can improve the label convergence time relative to the directly connected LDP peer. Because if it is directly connected LDP neighbors, two LSR link between if DOWN out, then LDP session will DOWN , however the purpose of the LDP session, another alternative paths can be used to carry LDP TCP packets , so, even if even if the link DOWN out, LDP session is still valid, all tags will be retained, while the link may soon resume LIB label in the update to LFIB go.
