Hello!
RE-S-1800x4 32GB could definitely hold more than 20M simple IPv4 routes.
It is because in my lab RE-S-1800X2-16G-S
mx480_re0> show route summary
Feb 04 19:40:41
Autonomous system number: 100
Router ID: 1.1.1.1
inet.0: 22000784 destinations, 22000785 routes (22000784 active, 0 holddown, 0 hidden)
Direct: 4 routes, 3 active
Local: 3 routes, 3 active
BGP: 22000777 routes, 22000777 active
Static: 1 routes, 1 active
mx480_re0> show system memory

System memory usage distribution:
Total memory: 16717508 Kbytes (100%)
Reserved memory: 437348 Kbytes ( 2%)
Wired memory: 1056028 Kbytes ( 6%)
Active memory: 5977108 Kbytes ( 35%)
Inactive memory: 5170424 Kbytes ( 30%)
Cache memory: 0 Kbytes ( 0%)
Free memory: 4076600 Kbytes ( 24%)
But be careful of these numbers.
First of all it is simple IPv4 announces without communities, Local Pref, MED, Single AS Path etc.
In production enviromment or with IPv6/EVPN/Flow Spec... RIB capacity reduces.
And we are talking only about RIB. Looks like 10M you hit FIB capacity.
To check RIB capacity without FIB protect BGP routes installation to FIB
routing-options {
forwarding-table {
export REJECT-to-FIB;
}
}
policy-options {
policy-statement REJECT-to-FIB {
term 1 {
from protocol bgp;
then reject;
}
}
}
Best regards
Vladimir

Subject: RIB capacity on RE-S-1800x4 32GB
Hi folks,
I want to know the RIB capacity on RE-S-1800x4 32GB.
I have a 10G IXIA port connected to an MX with the above RE, I am unable to push more than 10M routes.
Please let me know the maximum capacity. Appreciate your help.
Thanks & Regards
