Hi All

Is it possible to have one ISP 1gb connection and setup the bgp for it on 2 mikrotik CCR routers.
We are thinking about redundancy and would like router 2 to kick in if router one fails for whatever reason via VRRP

How can i achieve this

Secondly
we will eventually have a 2nd failover Line
So eventually we will have two ISP's Linked to both out CCR.
We will need to have BGP setup for each connection 2 BGP setups per CCR
Is this possible?

We only have /31 range from our ISP to use.
If so any guides i can follow, i haven't found any when searching

bgp

We only have /31 range from our ISP to use.

Do you have provider independent IP address?

Nope, don't think so

This ISP-link always has a cable that always needs to be inserted into something...and that will be your SPOF.
With a /31 that does not leave much flexibility to have a robust/dynamic setup...
You still can have 2 x CCR to have redundancy "LAN side" if these devices perform interVLAN routing or DHCP services or stuff.

ONCE you have that second ISP link, then I agree, a redundant setup is possible without too much issues, through BGP that can work, depends if the second link is with the same ISP.
Other nifty tricks also exist to switch over.

Hello.
I don't use BGP but have a VRRP stack. It secures interVLAN routing and network access throught 2 ISP (first ISP is the "main", the second backup).
VRRP is configure in "active-backup" mode - I mean the "master" is doing all the work and the "backup" is just waiting for "master" disaster If it happens the script enables the interfaces where ISP's are connected, when "master" is back another script disables it (in my case the master is always a master when both routers are online).
And it does work - maybe it's a clue for you. Or maybe just bullshi*, because you want to achieve something else

EDIT: If you are using Mikrotik certificates for something (like VPN connections), you have to be aware that they won't work out on both routers, every device needs it's own generated certificates, importing from another device won't work out.

Thank you all for taking the time to reply.

It has cleared up a lot and showed me a path forward.
I will definitely be back with more questions.

thanks again
