Internet FullView and BGP VPNv4

[angoran]

I have two Mikrotik PEs (PE1 and PE2) and an MPLS backbone between the two PEs:

MPLS : OK
LABEL LDP : OK
I receive the FULLVIEW INTERNET in the VRF of one of the PE (PE1), but the other PE receives only a tiny part of the FULLVIEW INTERNET (about 16 000 routes), why ?

Both PEs are Mikrotik 72 cores
PE1(OS version 6.48.2)
PE2(OS version 6.48.3)

I also notice a slowness when I ask to see some configuration on the PE2, ip route print where routing-mark = “vrf_wan” count-only, routing bgp information, etc. etc.
I have the impression that Mikrotik and VRF do not mix well.

Hi.

The RouterOS v6 routing implementation is not suitable for this type of deployment, it has a number of design constraints that mean it does not scale in performance with increased CPU cores, and this is made worse by the low IPC performance on the Tilera CPU’s in the CCR’s. There are also issues with stale labels and NLRI updates for L3VPN’s.

Best case you will have stale labels, worst case you will have the routing process crashing and causing 6-15 minute outages.

These issues will likely be resolved in RouterOS v7, but it is still in beta and the MPLS feature set is not complete yet.

Agree with nz_monkey 100% on this.

If you’re trying to bring routes from an IX across an MPLS network, maybe consider VPLS between PEs - from the IX port to the peering router.

Thank you for your responsiveness and the answers given !

I’ll try this one and keep you posted, thanks again !
