Ok, config is quite clear. Dependencies between
processes also.<br>
However:<br>
<br>
- if BFD runs on linecard, what happens if linecard
crashes ? Is it able to inform bgpd then ?<br>

<div style="">This is different kind of events. The line
card failure event have different handling procedure,
but result is the same - all processes will receive
appropriate notification. However, in case of iBGP or
multihop eBGP session you may want to have "fast-reset"
option configured.</div>

Right, I mean this should be quite logical so I should have known
this ;)<br>

there is some BFD parent process on XCRP that controls

<div style="">RIB is responsible for BFD provisioning from
control plane side.</div>

<br>
Ok. I know that redback/ericsson engineers/software designers are
good engineers so probably nothing wrong happens,<br>
but to be sure - what if ribd crashes ? Does it have any influence
on BFD/BGP while unavailable ?<br>

- I assume that BFD informing BGPd causes all bgp
session timers clear down instantly. Right ?<br>

<div style="">Yes, that is the reason why you would want
to use BFD for eBGP sessions.</div>
