Priority 0 : 9375000 Interface eth 0/0 OSPF supports the following network types: P2P ,where to take ccna exam, broadcast, NBMA , point-to-multipoint, and on-demand circuits The IETF is working hard to develop a 3- step process for point-to-point links only by implementing a 3- step adjacency on the broadcast link. R1#traceroute 55.55.55.55 Tib entry: 1.1.1.1/32, rev 2 TE overview LSP Seq Num LSP Checksum LSP Holdtime Set-overload-bit Router ospf 1 Mpls traffic-eng router-id loopback 0 mpls traffic-eng level-1 R2 configuration is as follows Flag position NSAP address to host name mapping Then you need the top-level tag, which looks at the next hop. The next hop is 5.5.5.5 , so be sure to find the 5.5.5.5 tag. As we have seen from the routing table, at this point R2 goes to 5.5.5.5 and actually enters the TE tunnel , then: The configuration of RouterB is as follows: Summary of tag processing actions ! The Level1 area is a collection of L1 routers and L1/L2routers , and Level2area is a collection of L2 routers and L1/L2 routers . The configuration of R2 is modified as follows: Layer 1 and Layer 2 set different metrics.

Note that both 304 and 404 are RSVP- assigned tags, so we should still pay attention to the tunnel when viewing the tags . The above table entry, 2.2.2.2 0[5] , be careful not to make a mistake, not the label corresponding to the prefix 2.2.2.2 , but the label corresponding to this tunnel .

The attribute tag attribute-flags is a 32-bit field. The CLNS address is required even if it only provides routing for IP . Packet data unit data unit Redistribute connected level-1 MPLS supports multiple Layer 3 protocols Ip address 10.1.45.4 255.255.255.0 We see that in the LFIB of R3 , going to the destination of 1.1.1.1 , there are two label paths for load balancing.

This is mainly achieved by electing a level2- capable router in each area as the area-specified level 2 IS and establishing a special adjacency relationship called virtual adjacency or virtual link between the areas. Ensure reliable diffusion of LSPs on point-to-point links Router-id 5.5.5.5 Interface eth 0/1 *Aug 18 09:06:07.919: 10.1.12.2 (Strict IPv4 Prefix, 8 bytes, /32) Next Hop Label Space ID is generally 0 , indicating that our label is a platform - based ( Per-platform ) label space. Domain-password After receiving the label from the tail router, the penultimate hop router uses the label as the outbound label of the TE tunnel , and assigns a label to the tunnel and places the label in the label object in the RESV message. Send it to its own upstream router. 55.55.55.55 [110/31] via 10.1.23.3, 00:03:44, Ethernet0/1 Activate the LDP after each router and bundled into a routing prefix assigned its own local routing table tags, such as the figure of X routing, all routers will itself as X assign a label route, then for X bundle routing labels save In the local LIB table. Subsequently, all LDP routers send their own labels for the bundled labels to their LDP neighbors.
