Tunnel transmit bandwidth 8000 (kbps)

Tunnel receive bandwidth 8000 (kbps)

I have the above shown in show interface tunnel on the router. Need to know if this 8000kbps is the bandwidth limit for that tunnel interface to transmit and receive packets.

I only have real experience with OSPF and if I remember right the default bandwidth for a tunnel is 9M if you do not set the bandwidth. No matter, because it is only the number used to calculate the route's metrics for placement in the routing table and not the actual limits. The tunnel limits will be met most likely through the transmission means and/or the physical interface capabilities.

Does that help?

Since tunnels are a logical construct, a default logical "bandwidth" is provided by IOS. Actual tunnel bandwidth is not restricted nor determined by this default. The default can be adjusted to reflect actual bandwidth using a tunnel's bandwidth statement.
