Does anyone have a link to something that will explaine route-map configuration? I have been searching CCO and so far have not found anything really helpful.
What I am trying to do is configure my internet router so that based upon the status of the link to my ISPs, a default route will be passed back into the core. I have added a secondary ISP and need the default route to change depending on the status of the primary link. I was thinking of setting the default route to the primary with a low metric and the default route to the secondary with a higher route by default. If the ping failed the primary default route would be reset with an even higher route, or removed completely, thus rolling traffic to the secondary. When the primary returned the primary default would be reset to its lower value and normal traffic flow would resume.
I have an IP SLA configured to monitor the primary link via a ping but I am having a hard time figuring out the route-map to set the default. I have an ACL with the ISP address to match and am thinking to use EIGRP to get the default back into the core and eleminate the manual static.
Basically I have:
I can manually make changes and make the roll of traffic happen but figurer there is a better automated way. In looking through confog guids and case studies on CCO, I think I have the pieces, just having problems putting them all together.
