TE tunnel Local Modify ldp holdtime , default 15S Mpls traffic-eng tunnels ip rsvp bandwidth LSP various types of TLV Tun Dest: Therefore, when R2 sends the label packet to the tunnel , the label that is pushed into the outer layer is 304 , and this 304 is obviously allocated by R3 , and is the label assigned by RSVP to the TE tunnel . Ip cef Routers use PSNP to request LSP latest version is lost or LSP . This applies to both point-to-point and broadcast links. Bw[3]: With the PHP mechanism: Signalling: connected The loopback0 address space of all devices is xxxx/32 , and x is the device number. 303 ! Load balancing of label packets MAC address,cisco ccna ccnp, etc. Can use the default or use this command to modify Router(config-if)# bandwidth ? With PHP's penultimate hop pop-up mechanism, C allocates POP labels for local direct-connected prefixes and advertises them to other LDP neighbors. The configuration of R4 is as follows: IS-IS Hello message ( IIH PDU ) Mpls traffic-eng tunnels ip rsvp bandwidth STYLE IS-IS routers belong to only one specific area Priority 2 : 9375000 A very important problem in MPLS networks is the synchronization of LDP and IGP . The so-called synchronization means that both IGP and LDP recognize that a link is the outbound link of the message to be forwarded . For example, in the above figure, all four routers run OSPF and activate LDP . Then on R1 , if it goes to the route 3.3.3.3/32 , the next hop in the routing table is R2 (assuming we adjust the cost ), and at the same time we receive the bundle of 3.3.3.3/32 prefix sent by R2 . The label 401 , then IGP and LDP are synchronized at this time, and R1 can normally use R2 as the next hop to forward MPLS label messages.
