DMVPN INTF state

[NaungHtunLwin0780]

Hi all,

I want to know about the INTF DMVPN state.And I also want to know about this below command:

->>>>>>  ip nhrp nhs x.x.x.x nbma y.y.y.y multicast

My testing for this command is :

R4#sh run int t0
Building configuration...

Current configuration : 220 bytes

interface Tunnel0
ip address 100.0.255.4 255.255.255.0
ip mtu 1400
ip nhrp authentication CISCO
ip nhrp network-id 1
ip nhrp nhs 100.0.255.2 nbma 10.0.26.2 multicast
ip nhrp shortcut
ip tcp adjust-mss 1360
end

Thanks , This is my requirement . I carelessly forget to do it . After I add tunnel soure and mode gre multipoint ,DMVPN is up .

One more point that I want to know is the usage of this command :

ip nhrp nhs x.x.x.x nbma y.y.y.y multicast

With the using of this , I do not need to write some command such that :

ip nhrp map multicast x.x.x.x

ip nhrp map x.x.x.x y.y.y.y

How it is ?

correct you are right 

ip nhrp nhs x.x.x.x nbma y.y.y.y multicast

OR

ip nhrp map multicast x.x.x.x AND ip nhrp map x.x.x.x y.y.y.y

these commands do same you can use any, i prefer second one.
