BGP - advertise prefix from 2 ISP (multihoming)

[zakwan]

Hi @tjh

Thanks for your advise and explanation.

@tjh

But yes, you should be able to advertise the prefix out both paths and, regardless of which router the traffic comes in, it should still be able to reach its destination properly. If you were advertising your VPN’s subnet out router B, but router B couldn’t actually reach your VPN, that would have broken things.

I believe that VPN is impossible to work with asymmetrical route (VPN going up from Vyos 1 coming in to Vyos 2).

Anyway, thanks again for your advise.
