Hi,

I have a problem when using VYOS 1.3.0 rc5 where BGP on that version can’t work properly. at the time of show ip bgp summary none of the peer bgp appears. here I attach my bgp configuration.

vyos@DR-VYOS-R630# run show configuration commands | grep bgp | strip-private

@maimun.najib
Your problem that you not set remote-as for this neighbor and save a party committed (configuration was committed with errors but you anyway saved it) configuration
Of course, after reboot, it will fail.

Delete this neighbor, or set correct remote-as.

I’ve added remote-as to the peer and it appears in the show ip bgp summary, but only 1 peer appears while in my configuration there are a total of 4 peers

vyos@DR-VYOS-R630:~$ show ip bgp summary 

IPv4 Unicast Summary:

Re-add please bgp configuration.
show conf com | match bgp copy it, delete all bgp config / commit
And paste configuration again. If you don’t see any errors after commit, you can save and reboot the router.

Did you check if there something in logs? Look for more information in VyOs logs, and also in remote peers log

@maimun.najib Did you ever get this fixed? Did you just delete the config and add it back.

I have a similar issue. However, I’ve upgraded from 1.2.8 to 1.3.0 epa3, and BGP is broken. Also, when trying to delete the configuration it complains about command specifics such as soft-reconfiguration inbound when trying to delete and other things. I have a mixture of peer groups, damping policy, route maps, etc.

I have the following output:

testrouter1:~$ sh ip bgp ipv4 unicast summary
% No BGP neighbors found

when deleting the configuration I see errors like:

vyatta-cfg-quagga[13453]: /usr/bin/vtysh -c configure terminal -c router bgp xxxxx -c address-family ipv4 unicast -c no neighbor x.x.x.x activate failed: 256

BGP clearly worked before with two full feeds.

@ocosa yes I removed and re-added the bgp configuration. after that for bgp it was running normally.

That’s what I had to do.
