Subject: [rtrlib] Quagga losses IPv4 addresses in RPKI
Hi All,
I hope you can help me.
I'm using Quagga + RPKI in Ubuntu with 4 GB of RAM and the latest RPKI RIPE NCC validator 2.16
If the validator is running and I start quagga, everything is fine, after I execute: "show rpki
prefix-table" I can see IPv4 & IPv6 prefixes; then, after some time (hours) for some reason IPv4
prefixes are lost.
Something like this:
---- cut here ----
my-rtr> sh rpki prefix-table
RPKI/RTR prefix table
Prefix Prefix Length Origin-AS
...[long output]....
Number of IPv4 Prefixes: 0
Number of IPv6 Prefixes: 1344
---- cut here ----
The compiled source I'm using is: https://github.com/rtrlib/quagga-rtrlib/tree/feature/rtrlib
It happens with Ubuntu 13.04 and 14.04
I have double checked the validator and it has all the ROAs, the communication between quagga
and the validator is ok, so, since the validator has all IPv4 ROAs I think the problem is
quagga-rtrlib. Anyway I'm willing to modify either one to make it work.
Thanks,
Alejandro,
Same problem here. Compiler options:
rtrlib:
cmake -D CMAKE_BUILD_TYPE=Release -D LIBSSH_LIBRARY=/usr/lib/x86_64-linux-gnu/libssh.so .
./configure && make && make install
quagga-rtrlib:
./configure
--prefix=/opt/quagga
--localstatedir=/var/run/quagga
--enable-vty-group=quaggavty
--enable-rpki
--sysconfdir=/etc/quagga
--enable-exampledir=/opt/quagga/share/doc/quagga/examples
make && make install
rpki config:
enable-rpki
rpki polling_period 3600
rpki timeout 600
rpki initial-synchronisation-timeout 30
!
rpki group 50
rpki cache 127.0.0.1 8282
using RIPE rpki-validator-app-2.20
@ip6li do you use the latest versions? The problem disappeared for Alejandro with the latest RTRlib update. See his daily dumps http://stats.labs.lacnic.net/RPKI/opendata/show_bgp-routing-with-validation/
I am using rtrlib from https://github.com/rtrlib/rtrlib.git (git pull from today)
@ip6li OK, I run the same setup in our testbed. How long does it take until v4 prefix disappear?
about 10minutes, bgp shows about 246246 prefixes announced by peer
At my side cache server connection runs for more than 30 minutes:
show rpki prefix-table
[...]
Number of IPv4 Prefixes: 14456
Number of IPv6 Prefixes: 2149
Via BGP peering I receive 537428 BGP routes.
Can you send a TCP Dump that shows the data between router and cache server until the prefixes disappear?
@ip6li, can you please checkout the latest RTRlib changes using the Master branch in https://github.com/rtrlib/rtrlib.git.
We also slightly updated our Quagga extension: https://github.com/rtrlib/quagga-rtrlib.git.
Would be cool if you try with these latest versions.
Closed.
