Hi,all,
Recently I met a strange question about route filter on Cisco3550 and
Cisco3825.And I permit them by using distribute-list in ospf
process,but some routes couldn't be appear in ip routing table.It is
the route to 10.102.0.0/16 which is from H3C MSR 5040 router.As I
remove the distribute-list,then it would be view in routing table.It
can be viewed in ospf database.Who can help me?
The following is my configuration:
On Cisco3550:
router ospf 3700
router-id 10.255.254.249
log-adjacency-changes
redistribute connected metric-type 1 subnets route-map 10-net
network 10.255.254.248 0.0.0.3 area 6
distribute-list prefix routein in
!
ip prefix-list routein seq 5 permit 10.31.0.0/16
ip prefix-list routein seq 10 permit 10.51.0.0/16
ip prefix-list routein seq 15 permit 10.60.0.0/16 ge 23 le 24
ip prefix-list routein seq 20 permit 10.102.0.0/16
ip prefix-list routein seq 25 permit 10.250.0.0/24 ge 29 le 30
ip prefix-list routein seq 30 permit 192.168.16.0/22 ge 23
!
And the following is routing information:
