We have a branch office connected via 6Mpbs MPLS, but they use a GRE tunnel to allow for static route redistribution. My question is, since the tunnel is configured for 9Kbit, it will not use the available bandwidth for the MPLS 6Mbps?
router-nj01#sh int tunnel 2
Tunnel2 is up, line protocol is up
Hardware is Tunnel
Description: Tunnel to Indianapolis
Internet address is 192.168.150.6/30

Encapsulation TUNNEL, loopback not set
Keepalive not set
Tunnel source 184.108.40.206, destination 220.127.116.11
Tunnel protocol/transport GRE/IP
Key disabled, sequencing disabled
Checksumming of packets disabled
Tunnel TTL 255
router-nj01#sh interfaces ser1/0
Serial1/0 is up, line protocol is up
Hardware is DSXPNM Serial
Internet address is 18.104.22.168/30
MTU 4470 bytes, BW 6015 Kbit, DLY 200 usec,
reliability 255/255, txload 10/255, rxload 26/255
Encapsulation HDLC, crc 16, loopback not set
Keepalive set (10 sec)
Last input 00:00:00, output 00:00:00, output hang never
Last clearing of "show interface" counters never
then that will be the maximum amount flowing over the MPLS?
No, the limiter will be based on the physical interface used for traversing from tunnel-to-tunnel.
For instance, if the tunnel is using the serial interface as the source and another serial interface as the destination (based on both serial running 1.5Mbps) then the speed of the tunnel will be 1.5Mbps.
