I was able to solve the issue by statically routing the connected /29 out t=
he connected interface, that way it overrode the BGP learned route for the =
same subnet (unfortunately this might have been a multi-homing issue that r=
esulted in asymmetrical routing to the primary peer via the secondary peer,=
since the secondary peer session was already established). I thought BGP w=
as "intelligent" enough to run the TCP session over the directly connected =
interfaces on the same subnets. I can understand this being an issue with m=
ultihop but not multi-homing.=0A=0A=0A=0AOn Wednesday, December 18, 2013 7:=

though I have seem this on the message boards I am little confused in that =
the ISP is telling me that there is no authentication enabled on the Junipe=
