Hello
looking at your topology i would say the default route should point to the asa as most probably that is the gateway for external network traffic.

 

By the way the default does not have to be a connected or next hop ip/interface sometimes it can be a recursive static default which isn’t one of the above - it can be a next hop ip address related to another route existing in the route table  so for traffic to reach its destination via a recursive route the rtr will lookup the recursive nexthop ip address and find another route that will then be used to forward the destination traffic.

is this switch acting as Layer 2 ?

 

If the firewall is HA mode you should have VIP IP, so you can point to that IP address.

The switch has SVI ip address

if the north is active ASA then Yes you can.

Hello,

 

the short answer is: no. The default gateway (or default route) needs to point to a next hop address. So 10.61.10.1 will not work.
