I have 2 pairs of Cisco ASR's they both do IPsec with GRE and have HSRP enabled. Here is each sides config below. I need network 7.7.7.16/28 to be advertised from one side to the other but it does not show up. The relevant pieces are below

Hello Gerard,
how are your tunnel source and destination connected ? It looks like you are advertising the tunnel source in OSPF:

Hi George,
I use the Lan IP address of each side as its tunnel source and the Lan IP of the other side as its destination.
On the side with the route I want injected in ospf.
HMK-WIN-ASR1006-P#sh ip int b
GigabitEthernet0/0/0 156.79.x.x (WAN side)
GigabitEthernet0/0/1 7.7.7.21 (LAN side interface)
Tunnel0 10.99.99.1
On the side I want to receive the route.
MK-ASR1006-HE2#sh ip int b
GigabitEthernet0/0/0 162.94.x.x (WAN side)
GigabitEthernet0/0/1 192.168.21.198 (LAN side interface)
Tunnel0 10.99.99.2
