IS-IS level2 to OSPF Outgoing interface If the two LDP neighbors do not match each other when they exchange parameters, this command can slow down the trial LDP session establishment time between the two LDP LSRs . If the session establishment fails, the next retry interval. Will multiply until the maximum-backoff timer expires. *Aug 18 11:26:02.546: P2P Links: Multiacces Links: Distribution mode : Label Distribution Mpls traffic-eng tunnels mpls ip 10.1.23.3 Ip cef Used to confirm and request link status information Destination-based load balancing is actually achieved by HASHing the destination and source IP addresses . In other words, it is actually based on source and destination address pairs for load balancing. *Aug 18 11:26:02.546: R1.00-00 basic configuration 0x9540 *Aug 18 04:37:06.239: Hop Addr: 10.1.12.1 LIH: 0x02000403 i ia 10.1.24.0 [115/148] via 10.1.123.2,ccna certification syllabus, FastEthernet0/0 i ia 10.1.45.0 [115/158] via 10.1.123.2, FastEthernet0/0 i ia 10.1.34.0 [115/158] via 10.1.123.2 , FastEthernet0/0 C 10.1.123.0 is directly connected, FastEthernet0/0 i*L1 0.0.0.0/0 [115/10] via 10.1.123.3, FastEthernet0/0 Mpls traffic-eng tunnels ip rsvp bandwidth R3 configuration is as follows (Note that, Area0 and area1 must activate the MPLS the TE ): !!

Then, when R1 calculates the path for this tunnel , R1 converts the affinity value 0x00000001 into binary, which is configured with the two interfaces of R1 . The two attribute-flags values ​​are compared one by one. Since our mask configuration is 0x00000001 , it is also written as binary, and the mask is 1 bit, which must be matched, so only the R2-R2 link is available. . In the actual network deployment, we can flexibly define the meaning of each bit of the link attribute according to our own needs , and combine the affinity attribute to control and avoid the path selection.
