l2l tunnel only established on one end

I have a l2l tunnel only can established the tunnel on one end; the other end unable to initiate the tunnel if the tunnel is timeout.

I noticed the role on the other end is "responder".

Can i configure the tunnel so that both end can initiate tunnel establishment?

Alternatively, is it possible to configure so there is no timeout once the tunnel has established?

Thank you.

l2l tunnel only established on one end

In an IPSec LAN-LAN tunnel, the role of responder generally can vary according to which end is first presented with interesting traffic requiring the establishment of the tunnel. Timeouts (and associated tunnel renewals) are a natural part of IPsec and should not generally cause issues.

If you provide the relevant sections of your devices' configurations, you have a better chance of getting a more specific and actionable answer.

Hello Kope,

Please provide relevant configuration of both sites so we can determine why this is happening.

Regards,

Julio
