prodnxsr0020 runs FRR/OSPF hand-configured; bring its routing config under puppet without touching interfaces, firewall or dnsmasq.
- add roles::infra::network::router (base + frrouting + frr_exporter)
- enable ip_forward and disable rp_filter via sysctl::base
- add prodnxsr0020 OSPF config (dum0, dum1, bond0.201; src 198.18.21.160)
- pin dns, consul and router-id to dum0 instead of the WAN-facing primary IP
- listen sshd on 127.0.0.1 and dum0 only, knocking out the common WAN primary IP
- keep resolv.conf on the local dnsmasq (127.0.0.1)
