I have 3 sites. one is HQ and the other two are branches. The branches connect to HW via serial lines and the Branches connect to each other via Fast Ethernet lines. I would like to give the sites a default route via eigrp ip summary commands and have fail over. I have pushed the default route from HQ, but fast ethernet side shows as path for all other networks. How can I make the Fast ethernet side a backup default route with no route advertisements?
I have this problem too.
