Hi,
Can you provide a topology diagram and put the output of:
-sh ip route 10.10.10.10
- sh ip cef exact-route "vlan1 IP" 10.10.10.10
-sh track 123
- sh ip sla statistics 1
Regards.

Hi,
I am trying to track a default route pointing to ISP on my easy vpn client router, the router doen"t have a static route to 10.10.10.10 and there are no ip cef route to the specific destination.
The below status is when the track command is included in the static route.whenever i include a track command in the default route my vpn connection disconnects and when i remove the track command the vpn connection comes up.
ip route 0.0.0.0 0.0.0.0 dialer0 track 123
TEST#sh track
Track 123

Hi,
when i put ip route 0.0.0.0 0.0.0.0 dialer0 everything works fine. but when i put ip route 0.0.0.0 0.0.0.0 dialer0 track 123 everythng goes down.
I tried still the ip SLA commands which you sggested but still the situation is same.
IOS :
flash:c870-advipservicesk9-mz.124-24.T1.bin"
Thanks

"10.10.10.10 source-interface Vlan1"
Is the network segment on vlan1 is being natted or no-natted if it goes via for VPN connection correctedly?
It seems to be that what it is failing.
thanks

Could you manually ping ur destination, sourced from VLAN 1?
because here i dont see any problems with ur SLA, track n rtr are just doing the same thing in different versions.
most probabely the problem is with reachability itself, try to remove or change the source-interface extension
plz Rate if it helped,
Soroush.

Rizwan,
there is no option of rtr, i have always configured by rtr and it works fine,
TEST(config)#track 123 ?
interface Select an interface to track
ip IP protocol
list Group objects in a list
stub-object Stub tracking object
Thanks

Yes i can ping the tracking IP when it is configured in the router as ip route 0.0.0.0 0.0.0.0 dialer0 and there is a default route in the table
BUT when i add a track keyword with a default route ip route 0.0.0.0 0.0.0.0 dialer0 track 123 the default route from the routing table is been removed immediately and this is the reason i m losing the connectivity.
Dear Rizwan,
Yes it is an Easy vpn client connection and it is network extension mode , the local internal IP reaches the server it is not Natted.

Hi Jack,
I believe, it is the ip (10.10.10.10) you are expecting a echo-reply from, must be disabled for ping reply.
Try, a different, interface ip at HO router's IP instead, a pingable IP.
thanks

Rizwan,
"No" this IP is pingable with a source address of interface vlan 1 when i configure a default route such as
ip route 0.0.0.0.0 0.0.0.0 dialer0
BUT
It it not pingable when a default route is configured such as ip route 0.0.0.0 0.0.0.0 dialer 0 track 123 becz what actual it is happening is that after applying the track command in the ip route when i do sh ip route there is no default route in the routing table.
Is it i have to upgrade the IOS for the router,it is strange becz after entering the track 123 command in ip route the default route disappears from the routing table.
Thanks

Hi,
