Sometimes we get the wrong IP back in traceroutes. Here is an example:
gigabit@kviknet01:~$ mtr -n -r -c3 185.24.168.181

1.|-- 212.237.176.65 0.0% 30.2 0.2
128.0.0.0 resolve no-readvertise
I can apparently have a working system by splitting my 0.0.0.0/0 into two
halves 0.0.0.0/1 and 128.0.0.0/1. Not very satisfying. There has to be an
explanation and fix?

My evpn with irb on an acx5448 is going ok except for one very strange
problem. The router refuses to use the default route 0.0.0.0/0 when routing
traffic via the irb interface.
The router itself will ping just fine:
baldur@formervangen-core3> ping routing-instance internet 8.8.8.8
PING
We have two datacenter locations each with a mx204 and a pair of acx5448.
The mx204 is used for ip transit, peering and subscriber management. The
acx5448 is for connecting servers. Remember the mx204 does not have a lot
of ports.
We also have an outside plant currently with 26 locations, each

I found the answer to this one. On ACX5448 and ACX710 the routing-interface
statement does absolutely nothing. Instead you need to use the undocumented
l3-interface statement at the same place. On the MX204 platform the
l3-interface statement does not exist. I will list the two configs

The ACX710 was clearly built for one or two mobile network operators.
There is no doubt about that.
Juniper have been making boxes that support both AC and DC for yonks.
Hardened and regular. What's so special about the ACX710? In 2020?
To be fair

If you can verify by PCAP on MPLS interface it would

How do you program in a static arp entry on an interface that is using

Eg.:

family inet {
unnumbered-address lo0.1;
}
}
