WAN Problem

hello Reyad,

i am not an expert.. but one idea could be to use the ip verify availability with ip sla tracks and with the appropriate set commands in the route-map change the AD of the interface. i am not sure if this is helpful at all, i haven't tested but i am setting up a gns lab shortly for this..

Re: WAN Problem

You may need to use eem and tracking for this. Try this:

track 1 interface  FastEthernet0/1 line-protocol

event manager applet Track-Down

event syslog pattern "1 interface FastEthernet0/1 line-protocol Up->Down"

action 1.0 cli command "enable"

action 2.0 cli command "config t"

action 3.0 cli command "int fa0/0"

action 4.0 cli command "shut"

With the above, if my fa0/1 goes down, I shut down my int fa0/0. You're going to need to create another one to bring the interface back up when your tracked object comes back up.

event manager applet Track-Up

event syslog pattern "1 interface Fa0/1 line-protocol Down->Up"

action 1.0 cli command "enable"

action 2.0 cli command "config t"

action 3.0 cli command "int fa0/0"

action 4.0 cli command "no shut"

WAN Problem

thank you Anastasios

thank you Blakley , i think your idea perfect for me , but if you can help me to make a tracking for the next hop ip address reachability instead of the interface status .

becouse some times the interface status shows up at both sides but no traffic pass through the link according to ISP problem . so that i prefer to have IP address reachability tracking if possible .
