Has no one an idea? It seems, that I am really stuck here. Do I have to
activate something on the other side (hence the AdminDown status?)

Hello David,
great tip. Unfortunatly BFD for BGP - though detailed documented - has
no examples flying
Hi Matthias,
What JUNOS version are you running on this router? Is other end router also
a Juniper router? Are both peers directly connected or is this a multihop
session?
Try this doc link see if it can help.

Hi!
That is the doc I have used for configuring.
Both routers are Juniper routers over a Laver 2 Link directly connected.
One router is 9.3R2.8 The other 9.4R2.9.

Matthias

Hi!
No, actually they are directly connected, so I do not know, why there is
a multihop output. Perhaps somehow he thinks to be not directly
connected and that is the problem?
Both routers are J6350.

Hi!
I do not understand why, but I do not see packets on the other router.
But there is no icmp either, when I ping the other side. The ES is on
one router, but in routermode. But I have explicitly allowed BFD now.
Strange, I do not understand, why the tcpdump is not working correctly.
Hi!
I see now only outgoing BFD packets... Perhaps I should better think
about using an IGP for the internal communication.

Hi!
We are using only iBGP between our routers on different locations. There
is a working BGP and data-connection between the two systems. Perhaps I
can somehow restart the BFD-daemon? Maybe it crashed?

Most daemons would restart.
What is in your log message file ?
Anything in /var/tmp or /var/crash directories ?
I have this running here across 2 x M10's and I don't see an issue, so
maybe firewall is causing it.
How are you allowing BFD traffic into the ES box ?
cheers

Nothing there:

Hi!
I wonder what the best practices for optimized switchovers would be? I
mean fast comprehension of failed BGP connections? A fibre cut or
something like that, how can I be sure, that my routers are detecting
the failed session as soon as possible? What would be the best
practices fpr
There are likely several answers to that, all dependant on your
topology and protocol use. But, a good place to start would be BFD
(bidirectional forwarding detection). Juniper has decent support for
it working with other protocols (OSPF, ISIS, BGP, RIP), notifying them
that something may be
