BGP ipv6 - can't establish peer - [Event] Incoming BGP connection rejected from "neighbor" due to maximum-prefix or shutdown

[pornmailbox]

Hi.
I spent ours to detect a failure in my bgp config or program itself. Only latest code from master resolves - "Interface: vmbrXXX does not have a v6 LL address associated with it, waiting until one is created for it" an error.
But I can't properly establish BGP ipv6 only connection with CISCO router. BGP connection has NoNeg status.

The output of "sh ip bgp summary'

IPv4 Unicast Summary (VRF default):
BGP router identifier 10.10.10.10, local AS number 25096 vrf-id 0
BGP table version 0

as far as I understood - something gonna bad with "Capabilities" during negotiation.

I'm not so close with it.
Any help or comments are welcome!

neighbor 2001:678:c5c::42 activate

Is missing under address-family ipv6 unicast.

[pornmailbox]

Hi. I can't see this command in running config after I apply it. Seems this is due to

bgp default ipv6-unicast

in my config.
I'm ordered a list of using capabilities from my uplink. In a few days I'll obtain it.

New correction - I'm trying to establish bgp connection with - MAC Address: EC:38:73:E8:88:30 (Juniper Networks).

something like #12763, but with ipv6 only.

[ton31337]

Ah, yes, missed bgp default ipv6-unicast in your config.

But I can't properly establish BGP ipv6 only connection with CISCO router. BGP connection has NoNeg status.

Probably because another side is not enabled this peer for IPv4 unicast? If you list the peers with show bgp summary (without ip) or show bgp ipv6 unicast, you will see the neighbors properly.

No. I have established link ipv4 bgp on another device right now.

But I can't ping any host inside FRR. No traffic there.

The story.
Due to insufficient memory on my old cisco, I had troubles while establishing a new connection with Local Internet peering - about 250000 additional routes.
In this case I moved to FRR. I successfully established bgp ipv4 connection with this juniper and joined peering network.
I have some multicast groups, formerly routed by my old cisco. After I enabled PIM6, together with PIM, OSPF6, OSPF and BGP vie daemons config - my frr stopped establishing bgp. First investigation shows that with enabled PIM6 - it is impossible to configure and use router-maps.
Second trouble was as of first route in my config in ipv4 bgp is -

route ipv4 109.202.160.0/19 Null0.

Routes after this line is not working on frr-8.4.2 on proxmox Debian 11, latest 6.xx kernel.

I moved temporary back all my ipv4 internet to my old cisco and start establishing in a test mode bgp ipv6 only with my uplink.
Due to a bug #12229 in 8.4.2, I moved my testing laboratory to a gentoo virtual machine with latest mester-branch FRR compiled.
The result is still negative.
This juniper has a few hundreds connected local peers via bgp. Seems that there is some specific not usual settings in its bgp config.
I advertise correctly my network.
To turn off some possible mistakes or troubles with FullView table, I asked my uplink to advertise me a default ipv6 route only.
How I can enable low level debugging of my connection in FRR to investigate a possible reason of connection fail ?

My target is to establish bgp ipv4 together with ipv6 connection on the same FRR-router at once.

Later I'll try to add PIM (ipv4 only) t this FRR-router also.

[pornmailbox]

latest investigation.
FRR-8.4.2 on Debian 11 can't use route-maps with Juniper connection - I get such error "BGP: [W2Q8T-MZ8HF] [Event] Incoming BGP connection rejected from 2001:678:c5c::42 due to maximum-prefix or shutdown".
This is for ipv4 and apv6 also. Only prefix-lists allowed in address-family section and connection in this way will establish successfully.
You should use "soft-reconfiguration inbound" also/

With ipv6 bgp I use latest frr compiled from master branch.
But with ipv6 I can't get my network advertised to my neighbor.

Seems to that there is a bug in FRR - can't advertise ipv6 network to a neighbor. It present in config, but absent in 'neighbors advertise-routes"

Total number of prefixes 1

But I cant't advertise my routes -

test-frr-vm# sh bgp ipv6 neighbors 2001:678:c5c::42 advertised-routes
test-frr-vm#

BGP session is fine -

test-frr-vm# sh bgp ipv6 summary

IPv6 Unicast Summary (VRF default):
BGP router identifier 10.10.10.10, local AS number 25096 vrf-id 0

Total number of neighbors 1
test-frr-vm#

something wrong in my config with routes.

If I add to my config - ipv6 route 2a03:500::/32 Null0

I get my network announced. but packets wont walk.

May be someone can save my time ?

as it was reported here - http://docs.frrouting.org/en/latest/ipv6.html#router-advertisement-configuration-example
I added this line to the interface via vtysh and I get my ipv6 bgp working.
....
!
interface eth1
no ipv6 nd suppress-ra
exit
!
...
I installed latest FRRouting from master branch - https://github.com/FRRouting/frr/tree/8b985768bffa7a6cb0b571393e2ae2d119e303c7

P.S. I'm using for frr gentoo linux in lxc container on proxmox ve.

Wireshark reported me that my neighbor sends me correct announces. My guesses are over. I can't use my ipv6 bgp peer.
