spoke with dynamic IP

[Mahmoud]

I have dmvpn solution with spokes that have dynamic IPs. I know the spoke who should bring the tunnel up with the HUB

tried to use sla to keep it up but with no luck

my question is how to keep this tunnel up always (tunnel , nhrp,...)

[Rahul Govindan]

If you have some routing protocol running through the dmvpn tunnel, it will always stay up as long as the spoke will try to build a routing adjacency with the Hub. Also, SLA should work as long as the SLA traffic is routed correctly through the tunnel interfaces.

static routing is used. but for unknown reason for me the track with sla didn't provide the needs.

did nhrp has any ability to keep registration for ever?
