NEM Mode no IP address from pool, remote multiple subnet support

Hi,
I have an IOS router configured as an ezvpn server at the headend and I'm trying to connect a remote IOS router in NEM mode.

Im choosing NEM mode as the remote router has three user sub interfaces off of a gige interface. I would like  these subnets to be accessible from the ezvpn IOS server.

My understanding is that ezvpn will take care of the insertion of the remote site routes into the headend router routing table.


I notice that when the ezvpn connection comes up I see an automatically generated static route to one of the remote ezvpn networks, however there are three networks configured at the remote router with the crypto ipsec client ezvpn eztunnel inside statement. But only one network out of the three networks at the remote are visible in the ezvpn server routing table. The next hop is the virtual interface and the address of 0.0.0.0. I thought that I would see the address from the easy vpn pool but the headend is not assigning an address to the remote.
If I configure the remote router in client mode an address does get assigned to the remoter router and I can ping it from the headend.

In NEM mode there is no IP assignment and I dont see all the networks in the ip rouer table at the headend.

It may be that NEM does not support multiple sub interfaces?? May be this is a time to move to DMVPN if yo need more networks at he remote your no longer in the tele comuter realm and its time to move to DMVPN configured as a branch....may be.

Any insight into this would be great thanks.
