Hi All,

we have a lease line connectivity between head office and branch office

Traffice flow across the link comprises of voice and data.

However since there are two links of 64Kbps between both the office , We would like to load balance the traffic between both the links.

Right now voice and data traffic ratio is 70:30 i.e 70% of traffic flows from link 1 whereas 30% of traffic flows from link 2 resulting in degradation of voice quality when the data traffic is heavy.

Can we get detailed procedure to segregate the voice and data traffic

Also sample config will be of utmost help

thanks

Configure LLQ to prioritize voice traffic over data.

See link: http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120t/120t7/pqcbwfq.htm

You can load balance the two links this way as well using MLPPP or CEF.

Hope it helps.

Steve
