Ok, for me it was implicit to configure outbound filtering to upstream in
order to not become Transit AS.

A couple of suggestions:
1) If you run iBGP, be *sure* not to advertize the default route learned
from one edge router, through iBGP to the other edge router, and back
out the other upstream. You can use a filter list to prevent that.
I agree with you about your technique but :
Why do you
No, the filter lists would only be to prevent the default route from
being advertised back out the other upstream link. Note that usually
the BGP AS-path loop avoidance rules will prevent a problem in this
scenario (especially with only the default route being advertised), but
in a more advanced
If you don't want the run the IGP on the firewall, then just run
something between the 2 gateway routers. iBGP would do the trick, and
you are running BGP anyway. You could still use HSRP for your own extra
router redundancy, but not for upstream selection.

did more research, would a next-hop-self on RA and RB respectively do
the trick?

If I understand you correctly, I don't think that HRSP is what you
need. HRSP is good if upstream serial interfaces go down, or something
like that, or for router redundancy, but in your situation I would
suggest letting your IGP determine which upstream is active, based on
who is still
I have a very small network, only 3 networks so i really don;t want to run
an IGP. I especially don't want to run it on my firewall. The ISP suggested
the HSRP solution since we are using static route between our firewall and
these 2 routers. I know there has to be way to do this and am trying to
