Exactly=E2=80=A6 It=E2=80=99s not an issue, it=E2=80=99s expected =
behavior.
If you move the static up within the neighbor definition, it becomes an =
Anchor Route and Exa knows you want it announced.
If you leave it in the static routes section, then you either need a =
redistribution policy from static to bgp (not recommended) or you need =
some other sort of policy that tells exa that you want to announce the =
route.
