Hello,
I have a very simple routing setup like this:
R1 <-- IBGP (GRE) --> R2 <-- EBGP (multihop over physical link) --> TRANSIT PROVIDER
R1 and R2 are mikrotik routers with rOS 6.47.2 (latest stable) installed.
R1 has an IPv6 prefix advertised to R2 with my ASN. R2 then advertises it to the transit provider, still with my ASN.
This works correctly.
The transit providers send my full view IPv6 routes over BGP (he's using a private ASN), which are inserted in R2 route table and are preferred routes (there's no other ones, in fact), however, he does not advertises them to R1.
There's no filter involved and everything runs into a single BGP instance everywhere.
I cannot figure why this doesn't work.
I saw this post: viewtopic.php?t=82738 but it looks like it's the opposite issue (IBGP routes not sent to EBGP) and on an older version of RouterOS than mine.
Any idea of why this would happen ?
Looks like a bug to me.
Thanks !
