Hi Ondrej, Thanks for your reply. What is the recommended linux kernel verison for mpls if BIRD acts as a PE.
We have VM with Red Hat Enterprise Linux Server 7.3 (Maipo) Kernel 3.10.0-693.2.2.el7.x86_64 on an x86_64 And Bird 2.0.1 version, but it is not working. Can you please confirm whether the environment we have is supporting mpls. If not, what is the recommended kernel version.

Yes, incoming routes with labels received from RFC 3107 neighbor can be programmed to kernel IP table as routes with MPLS label for next-hop loopback (for outgoing traffic). Unfortunately, BIRD will not insert corresponding MPLS routes to kernel MPLS table (for incoming labelled traffic). Although this is probably not a problem for PE router, where either penultimate hop popping or static decapsulating MPLS routes can be used. -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santi...@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so." ============================================================================================================================ Disclaimer: This message and the information contained herein is proprietary and confidential and subject to the Tech Mahindra policy statement, you may review the policy at http://www.techmahindra.com/Disclaimer.html <http://www.techmahindra.com/Disclaimer.html> externally http://tim.techmahindra.com/tim/disclaimer.html <http://tim.techmahindra.com/tim/disclaimer.html> internally within TechMahindra. ============================================================================================================================
