Probably stupid BGP on Packet Tracer question

Hi everyone,

I have the following scenario -

HSRP1 router with 5 VLANs:

192.168.1.0/24

192.168.10.0/24

192.168.20.0/24

192.168.30.0/24

192.168.40.0/24

And this is connected to an ISP - both have BGP.

However I cannot simply advertise network 192.168.0.0/16 - is this a limitation or how its supposed to be?

Or i need to do additional configurations?

HSRP1:

router bgp 12345

bgp log-neighbor-changes

no synchronization

neighbor 1.1.1.1 remote-as 1

network 192.168.0.0 mask 255.255.0.0

Same thing if I try to set network 0.0.0.0 on the ISP router as a default route.

If I advertise the VLANs separately its all good but was just wondering about a summarized network space.
