MPLS supports multiple Layer 3 protocols 772 Explicit Route: 10.1.23.3 10.1.34.3 10.1.34.4 4.4.4.4 Tunnel: !! Bandwidth requirement is 20M Interface Ethernet0/1 So far, the basic configuration has been completed. Now let 's create a TE Tunnel on R2 and R5 : LDP is in Frame Mode . The LSR assigns a label to each route. The local direct route is assigned a POP. 0x18B7 If the highest bit (the leftmost bit) is 0 , the metric type is default metric . If it is 1 , it means the metric is not supported. Related standards: Periodic reoptimize Fa0/0 5 10.1.15.5 1564 msec 1124 msec 1484 msec IP interface address LSP Interface eth 0/1 !!

The lower the priority, the higher the importance. Ip rsvp bandwidth 2000 This command sets the total reservable bandwidth of the interface to 2M.

We call it ECMP ( Equal-cost Multipath ). Reservable Bandwidth[1]: IS-IS adjacency and network type Pop Label In this way, first R2 will prefer from the tunnel port to R5 , metric=1+1=2 . There are two options for R1 to R5 : *Aug 18 11:31:44.598: The maximum number of regional addresses configured by a single router must be the same as that of neighboring neighbors. By default, CISCO IOS routers support the maximum number.

The IS-IS process is then restarted and the LSP is sent starting with sequence number 1 . (In fact,cisco ccna routing and switching pdf download, this situation will not arise, because even generate a per LSP , but also to 136 years after the serial number can be from 1 to reach 0XFFFFFFFF .
