Hello list,
I'm a new in Bird word :).
I'm working on a Bird mock-up. I'm actually blocked on OSPF filters.
OSPF conf for First Router:
*protocol ospf OSPF {*
* import filter NFRANCE_OSPF_IN;*
* export filter NFRANCE_OSPF_OUT;*
* rfc1583compat yes;*
* area 0 {*
* interface "xn1" {*
* type broadcast;*
* };*
* interface "xn2" {*
* stub;*
* };*
* };*
*};*
OSPF conf for Second Router:
*protocol ospf OSPF {*
* import filter NFRANCE_OSPF_IN;*
* export filter NFRANCE_OSPF_OUT;*
* rfc1583compat yes;*
* area 0 {*
* interface "xn1" {*
* type broadcast;*
* };*
* interface "xn2" {*
* stub;*
* };*
* };*
*};*
Filters:
*filter NFRANCE_OSPF_IN {*
* if net ~ [80.247.224.0/20{24,32}
<http://80.247.224.0/20{24,32}>] && (source ~ [ RTS_OSPF_EXT1,
RTS_OSPF_EXT2 ])*
* then*
* {*
* print net, " is accepted => OSPF_IN Public
Nfrance";*
* accept;*
* }*
* if net ~ [0.0.0.0/0{30,30} <http://0.0.0.0/0{30,30}>] &&
(source ~ [ RTS_OSPF_EXT1, RTS_OSPF_EXT2 ])*
* then*
* {*
* print net, " is accepted => OSPF_IN
Interco /30";*
* accept;*
* }*
* else*
* {*
* print net, " is rejected => non OSPF_IN
compliant";*
* reject;*
* }*
* }*
80.247.227.2/24 is installed on Router 1, xn2 interface,
Export network 80.247.227.0/24 on router 1 is ok but Import on the another
router is KO.
Indeed,
If I use the condition: *if net ~ [80.247.224.0/20{24,32}
<http://80.247.224.0/20{24,32}>] && (source ~ [ RTS_OSPF_EXT1,
RTS_OSPF_EXT2 ])*
80.247.227.0/24 is rejected by the OSPF neighbor filter rule*
NFRANCE_OSPF_IN*
2016-11-25 16:31:28 <INFO> 80.247.227.0/24 is rejected => non OSPF_IN
compliant
If I use the condition: *if net ~ [80.247.224.0/20{24,32}
<http://80.247.224.0/20{24,32}>] *without *&& (source ~ [ RTS_OSPF_EXT1,
RTS_OSPF_EXT2 ])*
80.247.227.0/24 is accepted by the OSPF neighbor filter rule*
NFRANCE_OSPF_IN*
2016-11-25 16:42:18 <INFO> 80.247.227.0/24 is accepted => OSPF_IN Public
Nfrance
And when I check the bird route when network is accepted, I can see "OSPF"
bird> show route
0.0.0.0/0 via 192.168.0.254 on xn0 [kernel1 16:35:00] * (10)
192.168.0.221/32 dev lo0 [kernel1 16:35:00] * (10)
*80.247.227.0/24 <http://80.247.227.0/24> via 172.16.51.4 on xn1 [OSPF
16:42:18] * I (150/20) [192.168.0.223]*
172.16.51.1/32 dev lo0 [kernel1 16:35:00] * (10)
bird>
So I don't understand why *&& (source ~ [ RTS_OSPF_EXT1, RTS_OSPF_EXT2 ]) *does
not match when the rule is added to my filter ?
I use FreeBSD 10, Is there an issue on FBSD regarding RTS_* ?
