Re: CRS317-1G-16S+RM packet loss ether1

Could you give me more information about "known problem with the SRJ01 module linking on 100MBit"? What is a solution for that? Changing the module doesn´t help. On one side we have a RB2011 (only copper ports) and on the other side a CRS212-1G-10S with such a module. Sporadically it goes down to 10...

Re: Missing mikrotik snmp OID's

The mentioned OIDs are still missing.
So we need to monitor the psu state with snmp in case of one is failing.

Please fix this.

Re: Failover Script with Dynamic Wans

What is the difference between a physical disconnect and a logical disconnect?
Sorry to be unclear.

physical was meant if there is a problem on layer 1 (link drops)
logical was meant if the there is a problem on layer 2/3 (eg dhcp client renew won´t work)

Re: Failover Script with Dynamic Wans

Hi, if you have dynamic wan-addresses I assume that you use dhcp-client on that interfaces? If so, then just set different distances "Default Route Distance" within the dhcp-client. So when your main wan (with lower distance) drops, the other route will be active. This works for physical disconnects...

Maybe it´s not an answer at all.

But do you tought about using MPLS/VPLS instead of EoIP? It´s more efficient and the overhead is smaller.

Re: Download and upload two separate links??

You can also make your link transparent using MPLS/VPLS. It´s useful for Layer-2 connectivity (for DHCP...) Just use OSPF for routing with different cost, than create MPLS-Interfaces and in the last step create a VPLS-Tunnel between the endpoints. These tunnels you have to bridge with ethernet/vlan ...
