Hi all, im new to this forum so if this is in the wrong place etc please let me know.
I have configured the "router on a stick" with sub interfaces etc and connected it two my LAN which is all working good. My question is at the moment there is a single point of failure due to the fact there is only one link between the switch and router. Is there anyway of making it more robust by adding another link to a different switch or even two links through the one switch? im confusing my self and would like to know if this is possible and if so what configurations are needed, Any help would be much apreciated.
That is right. Router is a single point of failure but if you can spare another fastethernet link then atleast we can make interface redundancy possible for the time being. Now instead of going into configuration detail, let us know the model and IOS you are using. The very quick and robust method i can think of now is using EEM to detect the failure of first interface and enabling the other interface (that has already all the configuration).
Hope this helps
