Dear All,
We are planing an MPLS network. We are considering to put CCR as a PE Router.
Please share with us how many VRF instance will support by each Model of “Cloud Core Routers”.
Please share any info that will related to Mikrotik router performance in MPLS network implementation.
We have many CCRs as PE routers in a VPLS mesh. I don’t know if there is a documented limit but I’m sure it’s in the - or greater - range of XX,XXX.
As far as performance goes, we’ve had zero complaints or speed issues for MPLS services on the CCRs. One CCR1009 we have is passing >1Gbps of MPLS traffic with ~2% CPU usage.
Hi, we have MPLS network with cca. 50 PEs and five VRFs at the moment with 10-100 routes per each + a lot of VPLS stuff and everything is working fine.
We don’t have route leaking and setup of VRFs is simple (no different route targets combination, just Internet, voice VRF etc.) and setup is quiet stable, no issues with MPLS at all
So this can probably be answered best by MikroTik but we have created 150,000 VRFs (Routing Marks) in a CCR-1036-8G-2S+ as a lab test…so the objects can be created, but the upper limit of how many can be active with routes may be a different story. We probably could have gone higher and created several hundred thousand more but when generating them from a script, the router reaches a point where it takes quite a while to finish and once we got over 100,000, there wasn’t much incentive to keep going higher.
Here is the count on the VRFs we created in one of our lab CCRs
[xxxxxxxxxx@IPA_CCR01_Datacenter] > ip route vrf print count-only
150000The wiki claims that only 250 VRFs are possible:
“Not more than 250 routing marks are possible per router.”
You can create a lot of routing tables but only 250 will be active.
@mrz thanks for the info, however…
This is very limiting when using MikroTik in larger environments - 250 is fine for a PE router, but some P routers require more than 250 VRFs - when will this be added to the roadmap in ROS?
+1 for more than 250 VRFs
Why would you need VRFs on P routers? With typical setups VRFs should be on PE routers, P routers are used just to switch labels.
We maybe able to add more instances in MikroTik RouterOS v7.
Sorry for resurrecting and beating the dead horse, Is this holds true for ros v7 with CCR2116? the 250 VRF limit?
1024 is the current limit
