Cisco IOS XE - ip sla auto discovery

[dyoma]

Hi All

I have Cisco IOS XE Software, Version 16.09.08, ISR4431/K9.

When migrating a configuration from a Cisco 3945 (15.1(1r)T1) to a Cisco ISR4431/K9 (Cisco IOS XE Software, Version 16.09.08), I discovered that there was no "ip sla auto discovery" command. What is the alternative to this command for IOS XE?

All of the following commands migrated successfully except "ip sla auto discovery". How to add this command to Cisco IOS XE?

track 1 ip sla 1 reachability
!
track 2 ip sla 2 reachability

ip sla auto discovery
ip sla 1
icmp-echo 172.16.200.54 source-ip 172.16.200.53
ip sla schedule 1 life forever start-time now
ip sla 2
icmp-echo 172.16.150.1 source-ip 172.16.150.2
ip sla schedule 2 life forever start-time now
ip sla responder

if you specify source of ip sla echo why you need auto discovery ?

I think the config is correct and not need auto discovery

I really hope you’re right, I’ll test the router in productive mode, thank you!
Please tell me one more thing about DMVPN.

The “ip nhrp map multicast dynamic” command was entered without an error, but I can’t find it in the configuration itself by searching.

It defualt I think 

You can sure it there by using 

Show run all

See if it appear under correct tunnel interface
