combination with Route-Maps<BR><BR><BR>> Hello Armand,<BR>><BR>> I
guess you're running BGP as outside/external routing protocol, right?<BR>>
Well... That would explain why traffic is flowing the way it is: if
both<BR>of<BR>> your providers are supplying you with the same
as-path-lengths for most of<BR>> the prefixes - this is mostly happening
when both of them are of the same<BR>> tier-class like both are tier1 -
your router is always going to prefer the<BR>> the external path over the
internal one.<BR>> Example:<BR>> Here we can see that the network
3.0.0.0/8 can be reached in 5 as-hops.<BR>The<BR>> internal path (5.6.7.8)
as well as the external one have exactly the same<BR>> lenght and localpref
but the external one is being preferred. This is a<BR>> standard mechanism
in bgp (ebgp over ibgp).<BR>><BR>> *>
3.0.0.0/8
1.2.3.4
999 0 12345 3356 701<BR>>
