Hi, The setup is i got a static ip route on two core switch 6509 and an eigrp on the other two core switches 6509. The route thru WAN is very slow and i installed a leased line and place two routers in between.
I am planning to use EIGRP with redistribute but my dillema is how do i prevent other traffic/segment not to use it unless it's an email traffic? and if the line fails it will use the existing WAN line. i only know of access list but it will block all traffic but what if the line fails how do it automatically use our WAN?
