Quagga stopped working after updates in Stretch

Today, after package updates, in my DNS server using Debian Stretch, OSPF stopped working and thus the server does not belong to the DNS anycast group. When I try to do /etc/init.d/quagga start, the init.d script is no longer there. I shall say I am still using sysVinit, and not systemd. Nevertheless, I have quagga packages installed in the system. While I could in the past quagga had one package in Debian, nowadays it has installed the list bellow. The package version currently installed is 1.1.0-2 What is happening? $dpkg -l | grep quagga | awk ' { print $2 } ' libquagga0 quagga quagga-bgpd quagga-core quagga-isisd quagga-ospf6d quagga-ospfd quagga-pimd quagga-ripd quagga-ripngd
