Re: EBGP routes not advertised to IBGP peer [SOLVED]

I just noticed you're talking about IPv6. In IPv4, this works However woth Ipv6, recursive routing does not work in RouterOS 6.x so iBGP does not work...the routes will advertise but are not reachable.

Yes, OSPF (or any IGP) is needed to provide loopback reachability for an iBGP AS so issues in OSPF that cause routes to flap can affect BGP and cause the peerings go down.

iBGP is a little easier. OSPF can support ECMP and since iBGP uses a loopback to peer - advertised in OSPF as a recursive next hop, it works well.

The only caveat is if you also run MPLS - the LDP implementation that MikroTik uses is not ECMP capable.
