Hi guys, our network currently consists of 4 Mikrotik routers that communicate with each other via the OSPF protocol on a dedicated vlan. Another vlan is dedicated to WAN traffic
Yesterday we activated a VM with routerOS CHR which will serve as a transparent firewall for some virtual machines. we mapped the WAN interface (this VM will not have OSPF).
On the LOGs it appears:
ether2 excessive broadcasts / multicasts, probably a loop
ether2 is the WAN
doing a packet sniffer on ether2 the other 4 routers send us a lot of ARP packets:
00: 00: 5E: 00: 01: 0A is the MAC address for a VRRP interface with a VRID of 10, an interface with that address is trying to find an IP address with ARP.
But packets also come from physical interfaces and also from routers that do not have VRRIP, for convenience I have only reported 1 …
The only thing that unites these 4 routers is the fact that I run OSPF .. On the network there is another Router (which does not run OSPF) and in fact it does not transmit anything (but always receives the ARPs from these 4 routers)
