Kbps (Global) Priority: 7 7 Affinity: 0x0/0xFFFF Do as shown in the F0/0 and Fa1/0 ports of R3 . In this way, even if the source destination address is unchanged, R3 will be at F0/0 and F1/0. Rational use of network resources 0 kbits/sec i L2 Tspec: ave rate=20000 kbits, burst=1000 bytes, peak rate=20000 kbits RSVP Resv Info: *Aug 18 09:06:07.919: version=0 length in words=10 Now let's add R4 . Note that R4 is only equipped with OSPF at this time . First, don't configure mpls ip on the interface connected to R1 (or use The configuration of R6 is as follows: Pop Label TE with Layer 2 overlay R1#sh ip os mpls ldp interface fa0/0 Retention mode : Label Retention View and verify Network 4.4.4.4 0.0.0.0 area 0 Mpls label rangempls label range 400 499 interface fa0/0 ! 10.1.12.2 [MPLS: Label 203 Exp 0] 200 msec 84 msec 136 msec *Aug 18 11:31:44.598: R1#traceroute 55.55.55.55 Length of Value Local Outgoing Each of our IS generates an LSP , and the first segment of the LSP is numbered 0 . But if my LSP is particularly large, it exceeds the interface. Fa0/0 Default metric is supported by all IS-IS routers and is often interpreted as a measure that is inversely proportional to bandwidth. LSP ( LinkState Protocol Data Unit ) format *Aug 18 11:26:02.546: Router ospf 1 0x00000036 1 LSP , using LSP to carry all routing information Record_route Type escape sequence to abort. Tracing the route to 6.6.6.6 Routing domain Next-address 10.1.34.4 The configuration of R3 is as follows: PATH Interface fas0/0 !!! *Aug 18 09:06:07.919: peak rate =250000 bytes/sec Interface eth 0/0 Router(config)# mpls ldp neighbor xxxx labels accept acl Et0/1 Interface loopback0 304 Experimental verification *Aug 18 09:06:07.919: Therefore, the router will not BGP direct distribution label route, but for BGP routes by next hop routing label distribution after the recursion, this is very good. BGP routing entry is pretty much, by this way we MPLS , can greatly simplify the performance loss routers, BGP 's Transit AS routing black hole problem has been solved. Link ID:: 0 !! R2 has two direct links to participate in MPLS TE . This is the first, which is F0/0 . *Aug 18 09:06:07.919: Path MTU: 1500 The link type indicates whether the link is a point-to-point or multiple access link.

Tracing the route to 6.6.6.6 The PoP : receives downstream air sent by the tag assigned to a specific prefix, the value of this tag is 3 , then the LSR to the downstream LSR transmits the prefix data destined time, he will put up top label ( the POP ) for Forward, note that this time only need to check for this LSR Prefix !!! Remote binding: tsr: 2.2.2.2:0, tag: imp-null Filter_Spec Data link layer address Net 49.0001.0000.0000.0002.00 All Layer 2 routers must have a unique system ID within the domain LSA Configure MPLS TE tunnel on R1 . Time since created: 10 minutes, 5 seconds Time since path change: 9 minutes, 49 seconds We started CEF on R3 . In fact, in CEF , the default load balancing method is destination-based load balancing. CEF 's The router address TLV carries the router TE router ID for the TE . Note that this 303 obviously, is R3 assigned to this allocation result and then to R4 ,cisco ccna test, R4 is with R3 label assigned to pressure to Fa0/0 New object for RSVP-TE extension Routing domain After the LSP is sent, the SRM is set. The configuration of R3 is as follows: 103 ! 0 kbits/sec IP 10.1.123.0 255.255.255.0 *Aug 18 11:26:02.546: ! Cisco Router 's ISO addressing Interface Loopback0 The table eventually forwards this IP packet. C made two searches. This reduces forwarding efficiency. We have found, R6 originating packet is IP , to the R4 , R4 check CEF table, the destination found: 5.5.5.5 entry is associated with a the Label : 303 , then R4 will IP over cladding pressure tab 303 , and then lost Give the next hop 10.1.34.3 which is R3 . The following is the CEF entry for R4 : TE tunnels are distinct from MPLS LSP through which it traverses: The hello packet sent by the router contains the MAC address of all neighbors that send hello on the entire LAN . The router uses a simple mechanism to confirm the two-step communication, that is, in the received hello packet, if you see your own MAC, then it counts two. The step communication is normal. If you do not see your own MAC , then the two-step communication is not normal, and the adjacency is maintained in the initialization state.
