I have a configuration where I would like to redistribute from RIP to OSPF.
I would prefer to apply a filter to limit my distributions. I am running
RIP on an ethernet interface and OSPF on a serial interface. When I apply
the command:
router rip
distribute-list 1 out ospf 1
It filters the RIP updates out the ethernet interface. So the router seems
to ignore the fact that I told it to only filter when redistrbuting into
OSPF and instead filters regular rip updates. Here is some debugging
output:
Before applying distribute-list 1 out ospf:
--------------------------------------------------------------------
02:24:10: RIP: sending v1 update to 255.255.255.255 via Ethernet0
(190.27.2.3)
02:24:10: RIP: build update entries
02:24:10: network 87.0.0.0 metric 7
02:24:10: network 180.70.0.0 metric 7
02:24:10: subnet 190.27.1.0 metric 7
02:24:10: subnet 190.27.10.0 metric 7
02:24:10: subnet 190.27.11.0 metric 7
-------------------------------------------------------------------------
Notice there are a number of routes being advertised out E0.
Now I will apply the command:
----------------------------------------------------------------------------
-- R7(config-router)#router rip R7(config-router)#distribute-list 1 out ospf 1 R7(config-router)# 02:24:15: RIP: Distribute-list changed: sending triggered update R7(config-router)# 02:24:35: RIP: sending v1 update to 255.255.255.255 via Ethernet0 (190.27.2.3) 02:24:35: RIP: build update entries - suppressing null update ---------------------------------------------------------------------------- --------Notice the update did not have any entries. So the command distribute-list 1 out ospf 1 blocks routes from leaving the ethernet interface.
Why?
