Hello ,

I want to ask , we are replacing Cisco router with Mikrotik and we are using Cisco router mainly for a lot for GRE tunnels.

My question because on Cisco by default for the GRE tunnel keep alive it's 5 4

and I know on Mikrotik I can configure it 1 1 for example so when any GRE tunnel is down I can receive a response in in 2 seconds .


The question is is there any other protocol on Mikrotik to support keep alive I mean any additional configuration to have a better result once any of these GRE tunnel is down ?



Best regards

Already had a look at Netwatch ?

any additional configuration to have a better result once any of these GRE tunnel is down ?

What means "better"? Does it mean "detecting a failure in less than 2 seconds"? If so, you can use bfd, which can react in tens of milliseconds, but it is not available for ROS 7 yet as of time of writing this, and it can only be used when OSPF or BGP is used on the same link. And it comes with a cost - the faster response you want, the more frequently you have to send the keepalives, i.e. the more bandwidth you waste for overhead traffic.
