I was working on Vol 1 lab 21 on a task dealing with RSVP and over subscription.
On R2 I had no problems interface Serial0/2/0 description Serial Link to R5 bandwidth 1500 ip address 150.100.25.2 255.255.255.0 encapsulation ppp fair-queue 64 256 36 clock rate 2000000 ip rsvp bandwidth 3000 end On R5 though I get this: interface Serial0/2/0 bandwidth 3088 ip address 150.100.25.5 255.255.255.0 encapsulation ppp end R5(config-if)#ip rsvp bandwidth 3088 RSVP bandwidth (which is the bandwidth for the IP headers and data inside them, but not the required link layer headers) exceeds 75% of interface bandwidth. It may be that you need to enter the 'bandwidth' command to correct the system's understanding of the available bandwidth. If that's not the case, then: Due to bit-stuffing, layer 2 headers and layer 1 framing, and the need for routing and keep-alive traffic, not to mention the RSVP messages themselves, this is just plain too high. Configure your interface realistically for the bandwidth available. It will only allow me to reserve 75% of the bandwidth configured no matter what. I assume this is due to IOS version differences?
