Hello, Mikrotik guru!
Can RouterOS transfer MPLS Labels between AS?
This is a screenshot from simplified lab environment with border routers connected directly.
All "Router XX" is a mikrotik CHR routers and "Cisco XX" is a IOSv L3 Cisco Routers
I can`t manage to transfer MPLS Labels from AS 65001 to AS 65002 by Mikrotik!
but it has been done on same lab (see screenshot) with cisco routers as Inter-AS MPLS L3VPN – Option C without any problems
Here is 3 options how it can be implemented in theory:
1. Inter-AS MPLS L3VPN – Option A – Back to Back VRF, I tried to implement it without success
(example is here https://mellowd.co.uk/ccie/?p=3766
2. Inter-AS MPLS L3VPN – Option B – ASBR + VPNv4, unknown how to do in RouterOS
(example is here https://mellowd.co.uk/ccie/?p=3783
3. Inter-AS MPLS L3VPN – Option C – BGP + Label, can`t be done for sure because BGP limitations in RouterOS
( example is here https://mellowd.co.uk/ccie/?p=3804
Based on my current experience It can be only done by external hardware (Cisco or Juniper)
Please share your knowledge!
