Does the "tunnel bandwidth" statement (not the regular "bandwidth" statement as applied to a tunnel) apply to mGRE tunnels?
The only Cisco documentation I've seen regarding this statement has been in the context of RBSCP (Rate Based Satellite Control Protocol), not mGRE.
The reason I ask this is that in the case of an mGRE tunnel defined roughly as follows:
ip address 192.168.66.109 255.255.255.0
tunnel source FastEthernet0/0
tunnel mode gre multipoint
...the output of "show interface Tunnel1" shows:
Tunnel transmit bandwidth 8000 (kbps)
Tunnel receive bandwidth 8000 (kbps)
...8000 kbps being the default setting for "tunnel bandwidth". (8000 kbps is shown regardless of the actual bandwidth, so long as the "tunnel bandwidth" statement is not used.) Adding the "tunnel bandwidth transmit 15000" and "tunnel bandwidth receive 15000" statements will change the output of "show interface", but do they have any actual operational effect? The regular "bandwidth" statement seems to be used in EIGRP and bandwidth utilization calculations (such as rxload and txload, seen in the same "show interface" output).
In addition, the documentation indicates that "tunnel bandwidth receive" statement has been deprecated, so this discussion really only pertains to "tunnel bandwidth transmit".
I believe I am getting more than 8000 kpbs per second, but for logistical reasons I can't test this properly in a production environment.
