Ondrej,

I've 2 bird bgp routers internally connected with 2 links.
To make benefit of both links, i should have been using iBGP configured on a "stub" or loopback address, but there was an issue with (bird-ospf).
So i choose to use 2 iBGP sessions, using both links, to ensure redundancy

The reason for choosing the vrrp address seems to be logical as it is on IP in our "owned" range and not any of a transit.
I'd not see a regular way to setup such readonly monitor link.

i'll send you the configs of the 2 iBGP routers, and my monitor bird config .

Thanks in advance

Regards,

Arjan Filius

Why such strange setting?

BTW, for iBGP, the proper configuration is to have one BGP session with each
of these two routers.

To find the problem, i would need your config files (for all three
routers).
