L2L IKEV2 IPSEC VTI ROUTE BASED VPN - WONT ESTABLISH - ASA 9.10(1)17

Prime56
Level 1
Level 1

EDIT: PLEASE IGNORE. MY PRIMARY INTERNET AT THIS SITE IS DOWN.

 

 

 

Hi all,

I was going through my sites to configure these tunnels on. I get them up nice and easy with a config template paste but this one ASA just doesn't want to work. I've redone the config as well on both sides, nothing. I don't want to say its the remote side config as it's working for every other site. I don't get much debug output, but on the problematic ASA this is my output.

Any ideas?

I was doing the config remotely, and I realized that my primary outside internet connection was down.....so it was using my backup (which has a completely different public IP) so thats why it wasn't connecting

show crypto ipsec sa detail in ASA,
local address must be the tunnel source
current peer must be the tunnel destination

wait your reply.

as I understand from your other post that issue is solve by change the VTI to S2S IPSec?

looking into the logs

 

M Trace-> SA: I_SPI=2D536454D12B92B7 R_SPI=0000000000000000 (I) MsgID = 00000000 CurState: I_WAIT_INIT Event: EV_NO_EVENT

seen like the remote site is not responding at all. is the tunnel is configured on the other side? what logs you see on the remote side (if you have access to it?)

 

1. check the phase 1 is setup properly on the remote end

2. make sure the encryption are matched on both firewalls

 

also show us the config and debug on the both devices.

please do not forget to rate.
