Hi Vahid,

IN other spokes which are working fine now its configurd as tunnel mode only

crypto ipsec transform-set 3des-sha esp-3des esp-sha-hmac
mode tunnel

I will also check HUB side debug .

Hello Guys

Sorry for the late reply.after upgrading the IOS its stable now .thanks for the inputs

Philip D'Ath · ‎12-06-2015

You can use transport mode if all nodes have a public IPv4 address. Tunnel mode works weather you have a public IP address or not on the outside. As long as all nodes are configured the same it is fine to be using tunnel mode.

Is the flapping happening at regular repeating intervals? if so, reasons I have seen for this happening are:

* Two spokes have the same IP address on their Tunnel interfaces (especially if there are two spokes flapping ...).

* Redistributing the "outside" addresses used for the internal in the interior routing protocol

* IOS Bug. Try comparing the IOS version of a working spoke with one that doesn't work. If they are different, try using the same IOS version as the spoke that works.

If the flapping is not occurring at regular repeating intervals (aka the tunnel actually works for a while and then breaks) then it is more likely to be a circuit issue.

It looks to me like the hub is not happy with this spoke, as there hub keeps retransmitting a packet. We would need a debug from the hub as well. However I bet one of the three things I have given above is the issue.

Hi P.dath The issue is, if the internet links (wan interface) if i shut down and no shut again ,the tunnel will take around 30 mins to comes up else need to reload the router . going to upgrade the IOS as well as there are bugs involved in nearby images.

Symptoms: The DMVPN IPsec sessions might get torn down and unable to re- establish themselves after experiencing link-flap events.

Conditions: In a scaled DMVPN environment, when physical-port link-state up/down events happen, there will be stormed IPSec events to tear down and/or re-negotiate the sessions; it might run into a bad state that it cannot establish new sessions. Hence, when those active sessions expire (by time period or volume based), it can no longer be re-created. After some period of time, no more active session remains on the router.

Workaround: Reload the router.

-------------------------------------------

HUB side debug will do after IOS upgrade

Philip D'Ath · ‎12-06-2015

Does your WAN interface have a dynamic IP address by chance? If it does, you'll need to add the below. Note it wont take effect with the current NHRP registration, but the next NHRP registration (you need to wait for the existing NHRP registration to time out so that the next one gets registered with the no-unique flag).

interface Tunnel 22

ip nhrp registration no-unique

I see lots of 'peer does not do paranoid keepalives', however you have keepalives configured in your spoke configuration. Make sure you have keepalives configured on the hub as well. Otherwise you could simply be having trouble with spi mis-matches on the hub side.

crypto isakmp keepalive 60 3

If it is neither of those two issues I vote on an IOS bug. If could be those issues being compounded by an IOS bug. Try going to the next "gold star" release. Especially try making sure you hub is on a good gold star release.

Need the same debug from the head end to see what it is saying,
