Hi,
I have recreated the topology of the the FlexVPN series in my own lab (another great video series BTW!)
So far, everything has worked exactly as per the videos, but I have now hit a roadblock:
In SEC0257 (DVTI Part 2) I have configured R1 to assign Tunnel IP addresses from a local pool.
The Branch Routers get the negotiated IP address correctly, and both Tunnels (to BR1 and BR2) come up OK.
However, R1 does not get the auto-generated static routes to the Tunnel endpoints via the Virtual-Access interfaces.
This means I don't have reachability across the tunnels and am unable to set up BGP routing.
I am using IOL 15.4(2)T4 images on EVE-NG for my Routers, but swapped R1 to CSR1000V (IOS XE 03.17.00.S / 15.6(1)S ) to see if it would help (it didn't).
Any ideas?

Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
a - application route
+ - replicated route, % - next hop override, p - overrides from PfR
Gateway of last resort is 1.1.1.1 to network 0.0.0.0
