Why would this tracker be down when I can ping the host?

[dodgerfan78]

Here is the tracker config:

tracker tracker1
endpoint-ip 8.8.8.8

It is applied here:

vpn 0
name VPN0_Underlay_VPN
dns 4.2.2.2 secondary
dns 8.8.8.8 primary
interface ge0/0
description INET1
ip dhcp-client
nat
respond-to-ping
!
tracker tracker1

vedge1# show tracker

VPN INTERFACE STATUS RTT
---------------------------------
0 ge0_0 UP Timeout

ame VPN0_Underlay_VPN
dns 4.2.2.2 secondary
dns 8.8.8.8 primary
interface ge0/0
description INET1
ip dhcp-client
nat
respond-to-ping
!
tracker tracker1

The status is down I pruned the output so you see tracker status is DOWN.

vedge1# show interface ge0/0 | tab

0 ge0/0 ipv4 192.168.3.10/24 Up Up Down 

router1# ping 8.8.8.8
Ping in VPN 0

64 bytes from 8.8.8.8: icmp_seq=2 ttl=115 time=13.5 ms

Any ideas?

Hello @dodgerfan78 

On your tracker config, specify source IP address.

[dodgerfan78]

It's DHCP, why should I need to do that? Plus, there is no source option in the tracker command.

I still checking I think the track is down because of rtt is long it 14 msec and I think the track by default use 1-3 msec

But let me complete checking

I believe the tracker needs to respond to http. I changed it to google.com and it works. This is pretty poorly documented but I found it on another forum.

Thanks a lot for update us 

Can I know for which service you use track 

To get completed pictures of issue 

Thanks

I dont know what you are saying by which service. The config is above, i just changed it to google.com instead of 8.8.8.8.

yes you are right, the endpoint should respond to http. I also read it on someones blogpost. The only problem is now that somehow if  the endpoint tracker is up the traffic is forced to internet tloc, ignoring the fact that mpls tloc is available and omp routing is available to the hub in datacenter. I did configure nat dia fallback accoring to the official configuration guide.
