But what if we want R1 to go to TE tunnel on .5.5.5.5 and 55.55.55.55 traffic ? Or Tunnel Id Outgoing tag or VC Next-address 10.1.24.4 Frame-relay map ip 10.1.123.2 301 broadcast Ip cef Setting the priority and maintaining the priority all indicate whether a TE tunnel can preempt another TE tunnel by using the corresponding value . The lower the priority, the higher the importance.

The following events will trigger a new LSP : Or Tunnel Id Then R1 and R3 receive a label mapping with a prefix of 2.2.2.0/24 and a label of 3 . At the same time, they also received the R2 updated route. Since the loopback interface route is updated by OSPF by default, it is updated in /32 mode. Therefore , the route learned on R1 and R3 about 2.2.2.2 is /32 bit. of. Then this is a problem, my routing entry is 2.2.2.2/32 , but the label message you sent me is 2.2.2.0/24 , it doesn't match, so R1 thinks that the label is going to Not 2.2.2.2 , just give an untagged , just like the LFIB table we saw for R1 . In this way, when R1 receives the label package and goes to 2.2.2.2 ,R1 will pop up the label stack of the label package, then find its own FIB table and forward the message out. This seems to be no problem in this topology, but in many environments, there will be problems, such as MPLS VPN . So how to solve it? Very good, R2 loopback port to an ip ospf network point-2-point , or change the mask.
