I using DMVPN to configure my tunnel between the Hub and spokes.
I discovered my pre-share key are shown in clear text when i do sh run config command.
How can i correct this.
crypto isakmp key xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx address pp.pp.pp.11 (note i just edit the key for the purpose of this post)
what IOS image is running on the hub ?
you can try to use
service password encryption
warning: but this will encrypt all passwords in configuration
check the syntax as I couldn't verify it.
Hope to help
