This article will help to understand the command to check how many Types 2 Routes can a QFX5120-48Y handle when running l2-profile-three with EVPN-VxLAN.

root@c21-39# set chassis forwarding-options?

> l2-profile-one MAC: 288K L3-host: 16K LPM: 16K. (restarts PFE automatically once the UFT profile is set)

> l2-profile-three MAC: 160K L3-host: 144K LPM: 16K. (restarts PFE automatically once the UFT profile is set) ß--This is va for L3 hosts -144K

so, looks like 160K type-2 routes for mac-address and 144K for type-2 mac+ip routes

" show pfe route summary hw " shows how many routes used.

QFX5120-48Y can handle well over 100,000 Type 2 EVPN routes, but the exact figure depends on the specifics of EVPN-VXLAN deployment, including factors like the number of VNIs, the configuration of Layer 2 profiles, and the overall network size.

The output seen under "show route table bgp.evpn.0 | match MAC | count" might show 2 entries for same destination, one for MAC and one for MAC+IP. Also, there would be ECMP paths for the same destination coming from multiple spines.

Below commands from PFE helps us to compare l2 and l3 route

start shell

su

cprod -A fpc0 -c 'set dcbcm bcm "l2 show"'

cprod -A fpc0 -c 'set dcbcm bcm "l3 l3table show"'
