Description

Test environment:

BGP connection with peer 172.32.0.3
Peer advertises the route 172.21.100.0/24
Static route for 172.21.100.0/24 via 192.168.20.1

Zebra has 2 entries for route 1 BGP and one kernel

K>* 172.21.100.0/24 [0/0] via 192.168.20.1, ix3, 00:00:10
B 172.21.100.0/24 [20/1] via 172.32.0.3, ipsec1, weight 1, 01:29:50

As expected, the kernel route via 192.168.20.1 will be installed to the FIB
However, if you delete the static route, Zebras RIB remains the same, and as a result BGP route will not be installed into FIB.
