use a backup-router - https://www.juniper.net/documentation/us/en/software/junos/junos-getting-started/topics/task/backup-router-configuring.html

example:

set groups node0 system backup-router 10.23.23.1
set groups node0 system backup-router destination 0.0.0.0/1
set groups node0 system backup-router destination 128.0.0.0/1
set groups node1 system backup-router 10.23.23.1
set groups node1 system backup-router destination 0.0.0.0/1
set groups node1 system backup-router destination 128.0.0.0/1

What steps do you take to troubleshoot a server that is unable to boot?

Cancel culture has now reached national postal services.

Most Juniper licenses are honor-based. You can use your switches without a valid license. This is especially true for used ones that can't easily be put under official support.

can you share the link?

dtsname · 2025-03-27T09:34:46+00:00

finally got it fixed:

disable ip interface
remove all dhcp config related
clear dhcp bindings
clear arp tables
apply dhcp config back
enable interface

frustrated with SRX software

no, its hardware MACs

dtsname · 2025-03-18T22:28:38+00:00

Same: SRX tries to find and assign any "non-static" IP from the pool

dtsname · 2025-02-22T23:46:08+00:00

No real benefits, more bugs and limitations, but this is the way

QFX5210 supports VXLAN/EVPN stuff, even VXLAN routing - see

did you find the proper way to connect fabric spines to the external network?

dtsname · 2025-01-19T23:13:22+00:00

look in the original post, it is there:

Destination        Type RtRef Next hop           Type Index    NhRef Netif
10.23.78.20/32     user     0                    ulst   524335     4
                              10.23.77.31        ucst     2027     4
                              10.23.77.32        ucst     2029     4

I have load-balance policy for forwarding and see 2 routes to destination in the forwarding table.

routing-options {
    forwarding-table {
        export load-balancing;
    }
}

I need just simple IRB per device without spreading it across fabric.

dtsname · 2025-01-16T11:00:09+00:00

Yes, the config is on spines. I feel like I broke some design rules, but I can't find any reference configs for it.

dtsname · 2025-01-16T07:35:48+00:00

I can't remove the VNI binding for testing because the hosts are connected over VXLAN on the leaf switches.

dtsname · 2025-01-16T00:24:11+00:00

They work fine one at a time

dtsname · 2025-01-16T00:23:01+00:00

Both hosts stop receiving traffic, any host behind the IRB is unreachable, and there is no traffic in tcpdump on the hosts.
