Introduction to RSVP

Hello Juan

This command configures the following on the interface:

  • 128 Kbps have been allocated for use with RSVP. This is the largest total bandwidth that can be set aside for RSVP purposes.
  • 64 Kbps is the largest bandwidth that can be reserved for a single flow.

So on this setup, you can have a maximum of two flows each of 64 Kbps. Any requests for anything larger or any request after two flows have already been allocated will fail. If nobody requests to reserve bandwidth, nothing will be allocated. These values are the limits set for this path.

Yes, this command is used to make the router act as a host and request bandwidth to be allocated. Note here that typically routers will not do this. This is a specialized command that is used under lab conditions. RSVP hosts are typically workstations, servers, IP phones or other end devices.

Yes, this command simulates another host device, but this time, the one that receives and responds to the RSVP PATH message. Again this is used for simulation and testing purposes and has no functionality in production networks.

To summarize:

  • The sender-host command is used to simulate a host generating an RSVP PATH message
  • The reservation-host command is used to simulate a host generating RSP RESV messages

I hope this has been helpful!
