Hello.
We’re using the LCR module with version 3.1.1 of Kamailio. We’re trying to
add two gateways, with the same IP address, we have this configuration
running in the previous version of Kamailio (v 1.5), without any problem,
but in this version seems to have some issues.
This is what I’m trying to do :
mysql> select * from lcr_gw;
+----+--------+---------+---------------+----------+------+--------+------------+-----------+-------+------+-------+---------+
| id | lcr_id | gw_name | ip_addr | hostname | port | params |
uri_scheme | transport | strip | tag | flags | defunct |
+----+--------+---------+---------------+----------+------+--------+------------+-----------+-------+------+-------+---------+
| 1 | 1 | GW_1 | 10.0.0.209 | NULL | 5060 | NULL
| 1 | 1 | 3 | 303 | 1 | NULL |
| 8 | 1 | GW_33 | 10.0.0.209 | NULL | 5060 | NULL
| 1 | 1 | 3 | 4411 | 1 | NULL |
| 6 | 1 | GW_6 | 10.0.0.212 | NULL | 5060 | NULL
| 1 | 1 | 5 | 308 | 1 | NULL |
+----+--------+---------+---------------+----------+------+--------+------------+-----------+-------+------+-------+---------+
And this is the output from the logs :
/usr/local/sbin/kamailio[2829]: ERROR: lcr [lcr_mod.c:818]: gw <10.0.0.209,
5060, > is not unique
What could be the problem?. Os simply the new LCR does not support have two
gateways with the same IP address?
Thanks,
Ricardo Martinez.-

in sr 3.1 two gws are considered unique if they have the same ip
address, port, and hostname. in sr 3.0 and in k 1.5 two gws are
considered unique if they have the same ip address and belong to same gw
grp.

Hello Ricardo,
I already wrote on this list about this issue. Currently the only way to
do it is to disable duplicate gws checking in sources itself.
In general, gw duplication checking should be extended to check not only
by ip_addr or its hostname, but to include 'tag' and even 'strip'
columns.
IMHO duplication checking could be removed at all and only DB unique
constraint checking used.

i'll need to check for possible problems and if none are found, i'll
remove the duplicate check.

it would be possible to cherry-pick the patch also to 3.1, but i don't
know if that is appropriate, because removing gw uniqueness check is not
strictly a bug fix. it is just a piece of not needed code.

currently the trivial change (do not check uniqueness of gateway's ip
address) is only in master branch. patch to 3.1 is included below.
