Erich,
With the little bit of info you are providing, it is hard to help. You
spoke of both inbound routes and outbound routes. Which direction are
you having issues with? Is the client using a Public or Private AS
number? Do your outbound filters only allow your network to be
advertised, or do they allow your router to propagate routes from one
peer to the next? Do your inbound filters filter out routes that include
your network? What are your filters allowing and blocking? Can you share
with the group your filters? I am assuming that your BGP peers are
showing established with the appropriate uptime. I would also ask if you
contacted your peers and asked them what they are seeing?

I am working with a client right now on multi-homing their network.
I have done multi-homing several times before and have never run into
a situation like this.
When we run a single Peer (receiving default route only) everything
works fine. When we run both peers then there is a route propagation
issue with some of the upstreams peers. The routes seem to come and
go (Some sites have no problem others load sporadically). This client
has their own IP Blocks. We have looked at multiple looking glass
routers and do not see any issue.
Internal network is OSPF . Routers are Mikrotik RB1100AHx2.
All routes are advertising fine, all filters in place are correct.
Anyone else seen an issue like this before?
