[Xorp-users] update ospf database after policy change

[Mykola Dzham]

When i change ospf export policy to "network, that rejected previously,
now allow", then changes affect to ospf database immediately. But whe
in change policy to "network, that accepted previously, now reject",
then changes not affect to ospf database. Is it bug? Is it possible to
apply changes without restarting xorp?

xorp-1.4 , FreeBSD 6.2-RELEASE

Here is a test:

Start state:

levsha at workstation.levsha.org.ua# run show route table ipv4 unicast final | match 192.168.15[56]  
192.168.155.0/24        [connected(0)/0]
192.168.156.0/24        [connected(0)/0]
levsha at workstation.levsha.org.ua# run show ospf4 database | match 192.168.15[56]

levsha at workstation.levsha.org.ua# show protocols ospf4 export   
    export: "to-ospf"

[edit]
levsha at workstation.levsha.org.ua# show policy policy-statement to-ospf   
    term testnet {
        from {
            protocol: "connected"
            network4: 192.168.155.0/24
        }
        then {
            reject {
            }
        }
    }
    term other {
        from {
            protocol: "connected"
        }
        then {
            accept {
            }
        }
    }

change "network, that rejected previously,now allow":

levsha at workstation.levsha.org.ua# delete policy policy-statement to-ospf term testnet   
Deleting: 
    testnet {
        from {
            protocol: "connected"
            network4: 192.168.155.0/24
        }
        then {
            reject {
            }
        }
    }
