Sorry but with those kind of information we cannot do anything.

Please provide more details about the setup (a schema would be very useful) and the routers configuration.

sorry,my English is not very well.please forgive me.Thank you!

Headquarters and branch through the ipsec connection, branch company of the router does not support the DMVPN just use the site - to - site connection.

Headquarters A configuration is as follows:

set interfaces ethernet eth0 address 27.XX.XX.XX/30
set system gateway‐address 27.XX.XX.1
set interfaces ethernet eth1 address 172.20.0.1/24

set vpn ipsec ipsec‐interfaces interface eth1
set vpn ipsec ike-group IKE-1
set vpn ipsec ike-group IKE-1 lifetime 28800
set vpn ipsec ike-group IKE-1 proposal 1 dh-group 2
set vpn ipsec ike-group IKE-1 proposal 1 encryption 3des
set vpn ipsec ike-group IKE-1 proposal 1 hash md5
set vpn ipsec esp-group ESP-1 lifetime 3600
set vpn ipsec esp-group ESP-1 mode tunnel
set vpn ipsec esp-group ESP-1 pfs enable
set vpn ipsec esp-group ESP-1 proposal 1 encryption 3des
set vpn ipsec esp-group ESP-1 proposal 1 hash sha1

set vpn ipsec site-to-site peer 0.0.0.0 authentication mode pre-shared-secret
edit vpn ipsec site-to-site peer 0.0.0.0
set authentication pre-shared-secret tset12345
set default-esp-group ESP-1
set ike-group IKE-1
set local-address 27.XX.XX.1
set tunnel 1 local prefix 172.20.0.1/24
set tunnel 1 remote prefix 172.30.1.1/24
set tunnel 2 local prefix 172.20.0.1/24
set tunnel 2 remote prefix 192.168.18.1/24
set tunnel 3 local prefix 172.20.0.1/24
set tunnel 3 remote prefix 192.168.19.1/24
set tunnel 4 local prefix 172.20.0.1/24
set tunnel 4 remote prefix 192.168.20.1/24
set tunnel 5 local prefix 172.20.0.1/24
set tunnel 5 remote prefix 192.168.20.1/24

All the above configuration tunnel can access 172.20.0.1/24
But can’t visit each other between tunnel.

How to configure after.
Thank you very much for your help.

Thanks.
