All routers run IS-IS Router# show mpls traffic-eng link-management bandwidth-allocation R2#sh run | Router ospf 1 ! Number of Links : 1 Mpls traffic-eng tunnels ip rsvp bandwidth 4 10.1.45.5 0 msec Both TE3 and R5 must establish a TE tunnel . That is, the TE tunnel must be bidirectional. The SWAP process is well understood. Note that the LSR only processes the top label when it processes the tag data for multiple tags in the tag stack. therefore Et0/1 SystemID Length : Identifies the length of the system ID . A value of 0 indicates a length of 6B , a value of 255 indicates a length of 0 , and other system ID fields may have a length of 1-8 bytes. ! Removal Trigger: configuration changed OSPF R4#sh mpls tr tun Message 10.1.12.2 Different LANs on the DIS . OSPF checks by embedding the interface MTU field in a DBD packet. This will cause R2 to calculate the route, from the tunnel0 port to the 5 and 55 route metric becomes 32+1=33 , which is greater than the metric=31 of the route taken from e0/1 . So the routing table of R2 has changed, and the routes of the 5 and 55 network segments have become: O We went to traceroute on R1 6.6.6.6 R1#traceroute 6.6.6.6 ! 4.4.4.0/24 Admin. Weight: 1 Local binding: tag: 100 In the SWAP process, after the label is exchanged, the inbound label TTL -1 is then copied to the outbound label TTL . 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 04:37:24.735: %LINEPROTO-5-UPDOWN: Line protocol on Interface Tunnel0, changed state to down The OSPF adjacency relationship will not be established until the LDP session is successfully established or the "synchronization hold time" expires . The synchronization here indicates that the local label bundle has been sent to the LDP peer through the LDP session . However,easy ccna pass, if A is activated on the router and MPLS LDP-IGP is synchronized, and there is only one link between A and B , and no other available path to B , the OSPF adjacency will never be established. Because OSPF waits for the LDP session is established, but the LDP session can not be set up because A can not learn in its routing table B of LDP routerID route, so enter an infinite loop, OSPF and LDP adjacencies will never Unable to create. In this case, LDP-IGP synchronization will activate the OSPF adjacency unconditionally , so that the link will advertise the largest.The metric value until the synchronization is complete.
