hello all,

We were looking ahead to implement BGP in our network, we have level 5 licence on our Mikrotik router. we are taking BGP for multi-homing with multiple ISPs over Internet.

I would like to know, if mikrotik can perform well with it and what things should taken care of before implementing BGP over mikrotik. How sucessfull it is till date.

THank

Leaving out some hickups that appear know and then.. it works OK. Not as good as quagga or cisco IOS but its OKish.

We have been using it in our community for almost 2 years know.

Do you use it for public IP ranges?
Is it stable?

Anybody who can comment if use BGP for public IPs ?

We are trying to set-up a new Internet Exchange in Malawi and we have worked out a router configuration using cisco bgp 4 as shown below. Now some us want to use Mikrotik router on the RB532 board and we are wondering how to convert our worked out cisco config to a corresponding mikrotik config.
- Could anyone please show us how to do a "peer-group" as done on the cisco config below?
- how do we do a corresponding router-map?
- what is the corresponding filter specification?

thanks in advance
