R - RIP, O - OSPF, B - BGP
C 10.10.10.20/32 is directly connected, Fiber 0/1

C 10.10.10.0/24 is directly connected, Fiber 0/1
default [42] via 10.10.10.20, Fiber 0/1 [IPSec]
B 0.0.0.0/0 [1/0] via 20.20.20.20, GigabitEthernet 0/0,

Note: If and when the main link fails, the default route learned through BGP is erased
from the routing table and IPSec is then used as a gateway of last resort. This can be
observed, for example, using Traceroute, which shows that the next-hop is through
IPsec.
The following shows the Routing table after the change:
