Hi Friends,

 

DMVPN Tunnel went to NHRP state After Spoke Router Reboot, Once tunnel interface configuration removed and deployed again issue got resolve. this issue happens when spoke router reboot. Kindly suggest on this. Please find below tunnel configuration of Hub and  Spoke end.

Hi Georg,

 

After applying static routes on spoke router i'm unable to ping NHS IP's but DMVPN status is normal. Any suggestion.

 

Note: I didn't reboot and check whether DMVPN status is moving to NHRP status.

The idea with the static routes was to make sure that EIGRP convergence is not the problem. When you reboot the router WITH the static routes installed, do the tunnels go into up state ?

Hi Sathish

 

Your configuration looks wierd. Following what you posted the simple configuration looks as followed:

HUB Tunnel Config:

interface Tunnel1
ip address 172.16.254.1 255.255.255.0
ip nhrp map multicast dynamic
ip nhrp network-id 101
tunnel source GigabitEthernet0/3.305
tunnel mode gre multipoint
tunnel protection ipsec profile ODMVPN2
!tunnel key 0
end


interface GigabitEthernet0/3.305
encapsulation dot1Q 305
ip address 69.46.229.X 255.255.255.252
ip nat outside
end

 

Spoke Config:

interface Tunnel0
ip address 10.254.254.20 255.255.255.0
ip nhrp map multicast 108.58.212.26
ip nhrp map 10.254.254.1 108.58.212.26
ip nhrp network-id 100
ip nhrp nhs 10.254.254.1
tunnel source GigabitEthernet0/0/0
tunnel mode gre multipoint
tunnel key 0
tunnel protection ipsec profile ODMVPN
!

interface GigabitEthernet0/0/0
ip address 75.99.252.X 255.255.255.248
ip nat outside

 

Theres is no "tunnel key 0" in the hub config and also the nhs server configured on the spoke need to be the IP address of the tunnel interface configured on the hub. This nhs address need to have the nbma address correspond to the source interface of tunnel configured on the hub. But in your configuration the HUB nbma address configured in the hub is 69.46.229.X and the HUB nbma address configured in the spoke is 108.58.212.26

 

Also the underlay configuration need to be Ok, both nbma addresses need to be reachable form each other.

 

Could you modify the config ?

Ok that sounds better.

 

Could you perform these tests from the spoke router.

 

Before the reboot when the tunnel is UP

show dmvpn

sh ip route 69.46.229.X

sh ip cef 69.46.229.X

ping 69.46.229.X

 

After the reboot when the tunnel is in NHRP state

show dmvpn

sh ip route 69.46.229.X

sh ip cef 69.46.229.X

ping 69.46.229.X

 

After the reboot when you remove the tunnel configuration

sh ip route 69.46.229.X

sh ip cef 69.46.229.X

ping 69.46.229.X

 

Also add a tunnel key on both tunnel interfaces.

Hi ulrickfr2001

 

Thanks for the response. Sorry right now production started i unable to do changes on spoke end. I will share you logs once production ended. 

 

many spokes are connected to that hub, if i deploy key on tunnel interface on HUB end it will get impact for other spokes is it?

Looks like everything OK on network ip configuration. Maybe the issue is related to the ipsec.

 

Could you provide the output of theses commands

 

1 when the tunnel is up and running

show crypto isa sa

show crypto ipsec sa

 

2 after the device's reboot and the tunnel is in nhrp state

show crypto isa sa

show crypto ipsec sa

Looks like on spoke side everything is OK. The packets are digested and verified in that tunnel before and after the reboot.

 

Could you confirm the same on the hub side before and after reboot?

Hello,

 

one other thing you could do is configure Interface State Control on the (spoke only) tunnel:

 

interface Tunnel1

if-state nhrp

Hi Georg,

 

Thanks for your response. I tired below config on tunnel 1 but no luck went to NHRP after spoke reboot. Any other suggestion.
