Description

When moving an interface with a DHCP default route between VRFs, the default route isn't removed from the old VRF.

Setup:

set interfaces ethernet eth0 address dhcp
commit
sleep 10
vtysh -c 'show running-config'

Building configuration...

Current configuration:
!
frr version 8.4.2
frr defaults traditional
hostname vyos
log syslog
log facility local7
service integrated-vtysh-config
!
ip route 0.0.0.0/0 192.168.128.1 eth0 tag 210 210
!
rpki
exit
!
end

Note the presence of a default route in the default VRF.

Bug:

set vrf name MGMT table 100
set interfaces ethernet eth0 vrf MGMT
commit
vtysh -c 'show running-config'

Building configuration...

Current configuration:
!
frr version 8.4.2
frr defaults traditional
hostname vyos
log syslog
log facility local7
service integrated-vtysh-config
!
ip route 0.0.0.0/0 192.168.128.1 eth0 tag 210 210

 ip route 0.0.0.0/0 192.168.128.1 eth0 tag 210 210
