We ran into a limitation on qfx5100 where you could not define more than "8?"
conditions
Ie:
Vlan members [ 1 2 3 4 5 6 7 8 9 ] would fail
But
Vlan members [ 1-9 10 20-25 ] would work
Chipset limitation if I recall. Best to open a JTAC case

Subject: [j-nsp] Vlan 111 on EVPN-VXLAN
** WARNING: This email originates from outside of the organisation **
Hi
I had a strange behavior in my environment where I use qfx5120-48y-8c switches,
in spine/leaf topology with EVPN-VXLAN configured.
I transport the VLANs via VXLAN between the servers that are below the leafs,
to my mx routers that are above the spines. To make my life easier, I use the
configuration of groups in the leafs, to "standardize" the aggregation
interfaces with the servers in the environment and apply the VLANs on all the
servers that are below the leafs at the same time.
I use the group config like this:
> show configuration groups VLANS
interfaces {
<ae*> {
mtu 9216;
unit 0 {
family ethernet-switching {
vlan {
members [ VNI830 VNI2925 VNI1819 VNI2819 VNI2829
VNI2853 VNI4018 VNI650 VNI680 VNI682 VNI750 VNI780 VNI782 VNI810 VNI815
VNI816 VNI821 VNI822 VNI826 VNI827 VNI828 VNI852 VNI854 VNI887 VNI910
VNI915 VNI916 VNI921 VNI922 VNI927 VNI928 VNI930 VNI952 VNI954 VNI987
VNI2953 VNI222 ];
}
}
}
}
}
> show configuration interfaces
apply-groups VLANS;
I just don't apply the VLANS group on the communication interfaces between the
leafs and the spines, on the other ports where the servers are connected, the
group is applied.
I have some VMs running OSPF with my MX routers on VLAN VNI2819, the problem
that occurred was when I tried to insert the VLAN VNI111, where the vlan-id is
111 and the vni is 111 in the VLANS group, when applying the configuration, the
communication automatically OSPF on VNI2819 dropped instantly, only coming back
after I removed VLAN 111.
Does anyone happen to know if there is any limitation on Juniper equipment,
where VLAN or VNI 111 is reserved internally in the system, I looked for
documentation and I didn't find anything about it.
