Hello,
As I could understand, we´re facing the same issue here with a BD8100. IP traffic runs ok, but when I run "enable iproute mpls-next-hop", I lose connectivity between the BGP peer´s loopback interfaces.
If I disable "enable iproute mpls-next-hop", I am able to establish BGP sessions OK, but not having MPLS forwarding enabled will not allow my MPLS VPN's to go through BD8100. We have tested this on EXOS 15.6.1.4 and 15.5.2.9, with same results.
We also have another similiar scenario (Cisco x Cisco BGP through Extreme Switch) using a X670 on version 15.4.1.3, and all works fine. I will repeat this scenario using X670 between CISCO routers and let you know the result.
IGP and Label allocation is consistent on all routers/switches, but there´s no connectivity.
I am guessing that one possible cause is the information I found on EXOS Concept Guide 15.4 (page 1139), where it says:
"Multivendor Support for Calculated LSPsUnfortunately, some MPLS implementations do not support the ability to forward packets received on
an egress LSP to their OSPF router ID and/or BGP next hop address.
If your MPLS network includes equipment that does not support this type of IP forwarding, you can use
configuration commands to explicitly control the use of calculated LSP next hops."
If anyone has any clue on how to solve this, please share.
