I am configuring a Multpoint GRE DMVPN on the Hub 3845 running 12.4.9 T code and on the remote 1811 running 12.4.15 T8 code.
the issue i run into is that when i shutdown the Multipoint Tunnel on the hub end the remote does not re establish dmvpn as long as the keepalive is configured on the remote tunnel. Once removed it comes on instanly. I have included part of th configs. any help is appreciated.
The keepalive 10 5 is not support, you can us e the folowing
You can change to ip nhrp holdtime=#xxx
Changes the number of seconds that NHRP NBMA addresses are advertised as valid in authoritative NHRP responses.
â¢The seconds argument specifies the time in seconds that NBMA addresses are advertised as valid in positive authoritative NHRP responses. The recommended value ranges from 300 seconds to 600 seconds.
thanks for your reply. I did reconfigure to OSPF and used the command holdtime like you suggested. However when i shut down the hub gre multipoint end shouldn't the remote NOT have the following information when i do the show ip nhrp command or am i using the wrong command to verify that the nbma address has dropped
sho ip nhrp
