Hi,
I have a problem with my current configuration. Yesterday we upgraded our one (1) of the private line into 60mbps from 6mpbs apparently I got a high latency.I need prioritize my connection to the higher telco bandwidth. Can someone help me whats wrong or need changes in my configuration before our private line is the same at 6mbps but now TELCO1 60mbps and TELCO2 6mbps only. see attached file for my sample network diagram and below is my configuration.
SITE A
TELCO 1 (60mbps) IP ADDRESS 192.168.230.2
TELCO 2 (6mbps) IP ADDRESS 192.168.231.2
interface Tunnel1
description ***OSPF TUNNEL for EASTERN DLL***
bandwidth 60000
tunnel source 192.168.230.2
tunnel destination 192.168.230.1
router ospf 10
router-id 192.168.254.1

Hello,
If it is your all configuration, traffic is forwarded through your slower link because ospf prefers your slower interface(physical) over tunnel with your configuration.
What is the reason for the tunnel while you have direct connectivity? Do you have IPsec on the tunnel?
OSPF on both sides do not match.
Use TCP adjust-mss 1476 on the interfaces to avoid fragmentation..
