Hi,
I have a small issue with OSPF filtering. From what I understand
distribute-list is used for filtering routes that are put in routing table
without affecting the LSDB. My current configuration is like this:
Thunder# sh run | be router ospf
router ospf 6845
router-id 194.102.255.75
log-adjacency-changes detail
redistribute connected subnets
redistribute static subnets
network 194.102.255.0 0.0.0.255 area 0
Thunder# show ip access-lists ospf-out | be 123.1.
630 deny 10.123.1.0, wildcard bits 0.0.0.255 (1 match)
640 permit any (725 matches)
Thunder#show ip route 10.123.1.0
Routing entry for 10.123.1.0/24
Known via "connected", distance 0, metric 0 (connected, via interface)
Redistributing via ospf 6845
Advertised by ospf 6845 subnets
Routing Descriptor Blocks:
* directly connected, via Bundle1
Route metric is 0, traffic share count is 1
On the neighbor:
Vision#show ip ospf 6845 database | in 10.123.1.0
10.123.1.0 194.102.255.77 104 0x80000001 0x00B4EE 0
After I apply distribute-list ospf-out out on the Thunder machine:
Vision#show ip ospf 6845 database | in 10.123.1.0
Does it really filter outbound LSA Type 5 ? Does this apply only on area 0
or does it work on any area ? I cannot find any references on outbound
filtering, except for type 3 on ABR.
Thanks for any help.
Cristian,
