At R4 , R4 pops the top label and forwards the packet to R5. Then, finally, the data is introduced into the established tunnel . In fact, after creating a TE tunnel on R1 ,cisco exam practice test, a local tunnel is in it.

The attribute tag attribute-flags is a 32-bit field. Next, you can test the forwarding of traffic on R1 . CSPF algorithm working mechanism R3.00-00 One goes from tunnel0 , cost=1000+1=1001 one goes from eth0/1 , cost=10+10+10+1=31 Comparison of terms between IS-IS and OSPF : Interface loopback0 In fact, this is a metric trick, but when we are thinking about it, remember to take the virtual path of the tunnel into consideration. RSVP-TE requests to establish an LSP tunnel according to the above path. The configuration of R2 is as follows (all configurations are omitted from the configuration of interface IP ): OSI has established standards for two network protocols for routing: ES-IS and IS-IS : Reservable Bandwidth[5]: 10.1.45.5 5.5.5.5 Uptime: 9 minutes, 33 seconds Selection: reoptimation R1.00-00 Next we R3 and R5 activate the forwarding adjacency, then R3 and R5 will be advertised in this region of the Tunnel- ( L in the manner of direct links). 0x4F65 Mpls traffic-eng tunnels mpls ip It is strongly recommended to enable this command to view some logs of the isis adjacency .

Later, the IETF in RFC 1195 are of IS-IS with modifications and extensions, called integrated IS-IS ( the Integrated IS-IS ) or dual- IS-IS ( Dual IS-IS ). Integrated IS-IS was developed to enable it to be applied to both TCP/IP networks and OSI networks, enabling it to provide dynamic routing information exchange for IP networks.
