Hello,
We have a medium sized DMVPN network that is working fine in Phase 3.
We have a new site that is using 4g as its primary connection. Every 12 hours the public ip address of this 4g connection changes causing the tunnel to drop.
By adding this command on the spoke the tunnel re-connects after about 5 minutes:
ip nhrp registration no-unique
This is not really ideal and wondering if anyone has an understanding of how this can be made better.
Manually executing clear ip nhrp also fixes the problem but again not ideal.
Using a Cisco 881 running 15.4 for this spoke.
Any ideas or suggests?
Adam
