Hi to all. Sorry for my poor english.
I have a remote site (A) connected to a access router (B). The remote site(A) has a dedicate leased line to the access router (B) plus an ADSL backup (with a tunne GRE) to my VPN tunnel concentrator (C). All are running eigrp has dinamic protocol
The access router (B) is connected to a outside ethernet por on a Firewall (D). The inside port od the firewall (D) is connected to a core router (E). The Core router (E) is running eigrp.
In this Core router (E) i have a static route to de firewall (D) to reach the remote site (A). The problem is when de teased line between the access router (B) and the remote site (A) goes down, the Core router (E) never lost the static route, because the next hop of this router (in this case is the firewall (D) never goes down. This situation cause that the traffic never pass to the ADSL.
I know that are somthing to solve this problem, but I not remember how this is called.
Can anybody hel me?
