[j-nsp] Filtering OSPF routes

[Michael Damkot]

Actually, you can only filter what your router exports:

[edit protocols ospf]
mdamkot at bigdog# set ?
Possible completions:
+ apply-groups         Groups from which to inherit configuration data
> area                 Configure an OSPF area
  disable              Disable OSPF
+ export               Export policy
  external-preference  Preference of external routes
> graceful-restart     Configure graceful restart attributes
> overload             Set the overload mode (repel transit traffic)
  preference           Preference of internal routes
  prefix-export-limit  Maximum number of prefixes that can be exported
(1..4294967295)
  reference-bandwidth  Bandwidth for calculating metric defaults
(9600..1000000000000)
  rib-group            Routing table group for importing OSPF routes
  spf-delay            Time to wait before running an SPF (50..1000
milliseconds)
> traceoptions         Trace options for OSPF
> traffic-engineering  Configure traffic engineering attributes
[edit protocols ospf]
mdamkot at bigdog# set export ?
Possible completions:
  <value>              Export policy
  (                    Open an expression
  [                    Open a set of values
[edit protocols ospf]
mdamkot at bigdog# set export

Well, to be clear, you can filter which routes your Juniper router will
import from OSPF. But you cannot prevent the router from passing along
routes in OSPF to other routers.
