OSPF Fast Hello

[Javier Lorenzo Prieto]

Hello,

I tested in the lab with 2 links ethernet and the result is the same: if hello tiem is less than 3 do not set the adjacency.

With Quagga software or Cisco routers, is possible. Is it possible to achieve rapid recovery using Bird?

Thanks in advance for your help!

How does multicast/broadcast frames work on that RF link?

If it is a Wifi-like link (i.e. it uses a 802.11 MAC), you most likely have
to avoid anything non-unicast like the plague. Please try OSPF in NBMA mode.
