However, periodic broadcasts through DIS Nolabel/505 Interface loopback0 N/P ! *Aug 18 09:06:07.919: Tun Dest: 5.5.5.5 Tun ID: 0 Ext Tun ID: 1.1.1.1 The configuration of R1 is as follows: Locally assigned labels are distributed to neighbors, and if there are multiple connections to a single neighbor, the label is valid on all connections. Then regardless of local Net 49.0001.0000.0000.0001.00 Type escape sequence to abort. Tracing the route to 5.5.5.5 In a CISCO IOS router without IPv6 capability, the general rules for load balancing packetized packets are as follows: Ip address 10.1.45.5 255.255.255.0 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 route is normal, and all three routers can learn the route of the whole network. and so: Ip address 1.1.1.1 255.255.255.255 Bw[4]: Mpls ldp igp sync holddown 5000 Selection: reoptimation Prior LSP: LSP TLV field of Level 2 route We assume that in the above topology, the bandwidth of all links is 10Mbps . Then after running the IGP protocol, we know that from R1 to R7 , the shortest path is R1-R3-R6-R7 , but because the traffic between R1-R8 in the network has already run on this path,cisco ccna papers, and it takes up a relatively high Bandwidth, the load of the link is too high, the traditional IP routing protocol is not so smart to take this into account, but with MPLS TE , we can let R1 to R7 take a better path. .
