Im playing around with some confederation test
topologies, and I have the current set up of sub-as.
65000 , 65100, 65200
they all peer with each other. Im seeing a route 10/9
in Sub-AS 65100 coming from both sub-as 65000, and
65200 peers. It is picking the route through as
(65000 65200) over (65200). The reason shows router
id? How is BGP confederation routes selected vs.
regular BGP routes. Is the SUB_AS path considered in
JunOS? and what about IGP metric to the next hop. It
is closer through 65200 directly in my topology. Can
anyone shed any light on this?
thnx
