Dear friends!
Is it possible to put dynamic PPPoE interfaces to specific VRF. For example, my internet table lies in vrf-internet, but newly created PPPoE interfaces are all in main routing table after creation.
It is not possible at the moment, you need to add static pppoe entries in server list and then add them manually to vrf
Oh… sounds very catastrophic for me… But could you please explain your statement in more detail. Sorry, but I don`t understand the procedure…
/pppoe server add name=client1 …
/ip route vrf add routing-mark=test inteface=client1
Thanks… understood. It is not so perfect for dynamic interfaces and pppoe aggregation services. But can I use some sort of script? Does ROS have tool set for changing routing table for interface in near online timescale?
Hi guys, I want to update this old topic.
We have quite big MPLS network and we started to work with Internet VRF, so we are putting PPPoE interfaces there manually.
The problem at the moment is that in Winbox we can add only 30 interfaces to the VRF, in terminal it accepts more.
Adding additional interface in terminal to VRF is complicated, because we have to enter all interfaces and then add a new one.
The question to Mikrotik support is if this limitation of 30 interfaces in Winbox will not cause some problems ?
Update: Limitation on amount of interfaces in VRF is 30, if we put more pppoe interfaces to VRF in terminal, PPPoE server/VRF will start become strange, so we are moving to DHCP now
I know this post is an old one and I had hoped Mikrotik would have resolved or increased this limit by now.
I have run in to the same issue when adding GRE interfaces to a VRF with a VLAN. One can’t add more than 30 through Winbox, but one can through the CLI. It seems even adding more than this value through the CLI it breaks.
I hope this limit can be increased as 30 interfaces in a VRF is very small.
Hi Guys,
has there been any development progress on this?
we are running a BRAS and I need to have dynamic pppoe interfaces land up in a VRF, currently the pppoe connects but the interface lands up in the main routing table instead of the vrf.
Things I have done:
- Add the pppoe server into the bridge where an interface Is in the vrf
Did a mangle rule with a prerouting chain that will take the source ip address and mark routing into the vrf
But this does not work. I don’t get the interface to land up in the vrf and or pass traffic and am now out of ideas on what more I can try.
Any advice of someone that has done it before would be appreciated.
With RouterOS v7 you can specify interface list which to use for VRF. And dynamic interfaces can be added in specific interface list.
thanks @mrz, is this release stable enough to put into production?
the problem is special with dynamic interfaces,when they are getting disconnected, automatically disappearing from VRF table (which is understandable). And its adding another interface (most of the time ether1).It’s posible to fix it up, on your end?
This is false, removed interface is never replaced with another one, instead of the old name internal ID is displayed.
And read two posts above, v7 solves the problem with dynamic interfaces by using interface lists.
Hi MRZ,
tried upgrading to version 7 and to be honest it doesn’t work, plus the bgp had a major memory leak that duplicated the learned routes every 2 mins until the box ran out of memory, so downgraded back to version 6.49.1
This is false, removed interface is never replaced with another one, instead of the old name internal ID is displayed.
I’m talking about v6.
So if i put dynamic (ppp-server) interfaces into vrf.
Once that interface bounces, will disappeared from the VRF list, which is understandable, but it will pop up another interface (most of the time ether1)
See the folowing pictures, what is false here?
v7 is still in development, not for production use.
Even in your pictures it shows “unknown” and did not replace it with ethernet as you stated.
Of course if you open configuration window, winbox must have a known value and then, yes it will pop to the first valid. It is not just vrf, this behavior is everywhere where you add dynamic interfaces in static configuration.
Also the one of the picture showing interface as blue.
not sure what does it mean, but i got your point. Clear enough
Yes, blue is another indicator. Blue means that value is changed and changes are not saved/applied yet.
@mrz, when or how can we get mikrotik to have dynamic interface placed into vrf’s via radius pppoe attribute?
so basically the radius attribute that will be pushed down will determine to which vrf a dynamic interface will belong?
Really Really need this feature!!
