Empty AFI/SAFI on JunOS IPv6 BGP sessions with same source address

Help
1

Hi,

Problem is as stated in the topic. I have two ipv6 BGP sessions on JunOS with the same source ID.

Router Config:

neighbor 2001:7f8:1::a500:6777:1 {
    description "ams-ix routeserver 1";
    family inet6 {
        unicast {
            prefix-limit {
                maximum 25000;
                teardown idle-timeout 30;
            }
        }
    }
    peer-as 6777;
}
neighbor 2001:7f8:1::a500:6777:2 {
    description "ams-ix routeserver 2";
    family inet6 {
        unicast {
            prefix-limit {
                maximum 25000;
                teardown idle-timeout 30;
            }
        }
    }
    peer-as 6777;
}

Sessions are up and receiving prefixes:

Poller/Discovery output:
(looks like the same identifier is being used for the sessions, so it gets overwritten by the last entry during the table/sql/rrd update)

jnxBgpM2PeerIndex.0.ipv6."...........GV... ...........gw.." = 141     <- Not working
jnxBgpM2PeerIndex.0.ipv6."...........GV... ...........gw.." = 142     <- Working


[0.ipv6............GV... ...........gw..] => Array
    (
        [jnxBgpM2PeerIdentifier] => 80.249.209.0
        [jnxBgpM2PeerState] => established
        [jnxBgpM2PeerStatus] => running
        [jnxBgpM2PeerConfiguredVersion] => 4
        [jnxBgpM2PeerNegotiatedVersion] => 0
        [jnxBgpM2PeerLocalAddrType] => ipv6
        [jnxBgpM2PeerLocalAddr] => 20 01 07 F8 00 01 00 00 00 00 A5 03 47 56 00 01

        [jnxBgpM2PeerRemotePort] => 179
        [jnxBgpM2PeerRemoteAs] => 6777
        [jnxBgpM2PeerIndex] => 142
        [jnxBgpM2PeerRoutingInstance] => 0
    )

This leads to an empty AFI in the overview page and consequently the values are not exported to InfluxDB either.
