I am having HO and BR office connected using DMVPN . it was working before but suddenly it stopped working. HO is having a lease line and the branch having ADSL link.
It will be highly appreciated if somebody could help me in resolving this issue
Please check the attached HO ,BR and debug files (public IP has been replaced with 184.108.40.206)
From the BR debugs, it looks like it is never getting a response from the HO router, that is, it sends the 1st packet on UDP port 500 to 220.127.116.11 but never gets a response and hence keeps retransmitting the packet and finally deletes the SA.
Please have a check if there is complete 2-way communication between the BR and HO routers on UDP 500.
All the best!
Thanks and Regards,
