[FROG] FRR 7.0 BGP does not connect to passive neighbor

Dear Christoffer,

Thank you for your reply!

I don't have access to my provider's BGP configuration I'm afraid. 
However I am pasting my end of the setup below.

It might be relevant to note that the BGP instance is configure inside a 
view, as I do not need anything to be installed in the main routing table.

I am using tcpdump to listen on the network interface for any traffic, 
and FRR doesn't appear to be initiating any connections to my upstream.

My BGP config:

router bgp 65001 view ISP
  bgp router-id 192.168.255.227
  bgp log-neighbor-changes
  neighbor 192.168.255.225 remote-as 65000
  neighbor 192.168.255.225 description default
  neighbor 192.168.255.225 update-source 192.168.255.227
  neighbor 192.168.255.225 timers 10 30
  neighbor 192.168.200.29 remote-as 65000
  neighbor 192.168.200.29 description full-table
  neighbor 192.168.200.29 ebgp-multihop 255
  neighbor 192.168.200.29 update-source 192.168.255.227
  !
  address-family ipv4 unicast
   network 10.10.10.0/24
   neighbor 192.168.255.225 soft-reconfiguration inbound
   neighbor 192.168.255.225 weight 1000
   neighbor 192.168.255.225 prefix-list AS65001-export out
   neighbor 192.168.200.29 soft-reconfiguration inbound
   neighbor 192.168.200.29 weight 1000
   neighbor 192.168.200.29 prefix-list noexport out
  exit-address-family
!

Kind regards,
Chris
