[quagga-users 13971] keeps losing ospf distributed default route

Hi,

I have quagga running on a number of different versions on different
OSes around my network and while it's stable everywhere, on my Fedora 21
machine it seems to lose the default route frequently.

The machine with the default route for the network is an Openwrt router
running quagga 0.99.22.3[-1] with the following configuration:

root <at> gw# cat /etc/quagga/ospfd.conf 
hostname gw
password *******
enable password *******
!
access-list vty permit 127.0.0.0/8
access-list vty deny any
!
line vty
 access-class vty

router ospf
    ospf router-id 10.75.22.254
    network 10.75.22.0/24 area 0

    redistribute connected
    redistribute kernel
    redistribute static
!
    default-information originate always metric 50

[quagga-users 13968] Auth errors when adding OSPF routes fast


Hi,

I run quagga for doing some OSPF stuff on CentOS. MD5 authentication
is being used within the OSPF entity.

In total I have nine (ten, when I'm firing up one management host that
only runs temporarily) machines in that setup. On CentOS 5 and 6 I run
quagga 0.99.23.1 (built from source) now, before that 0.99.15 from
repo, on CentOS 7 (the management machine) it's 0.99.22.4-4 from repo.

Four of those machines act as L2TP LNS for some ten thousand sessions.
Certain DSL connections are disconnected every 24 hours (due to
historical reasons), so that it happens from time to time that within
a few seconds several hundret or even two to four thousand routes are
being flushed and added *very* quickly when the CPEs return.

Only then I see this on several nodes running in that OSPF net:

2015/04/20 08:35:02 OSPF: interface ens4:12.34.56.130: ospf_check_md5
bad sequence 1429526867 (expect 1429526869)
2015/04/20 08:35:02 OSPF: interface ens4:12.34.56.130: ospf_check_md5
bad sequence 1429526868 (expect 1429526869)
2015/04/20 08:35:17 OSPF: interface ens4:12.34.56.130: ospf_check_md5
bad sequence 1429513257 (expect 1429513258)
2015/04/20 08:35:45 OSPF: interface ens4:12.34.56.130: ospf_check_md5
bad sequence 1429515808 (expect 1429515809)

Is that a known issue? How could I circumvent it?

[quagga-users 13964] BGPD and ECMP (pre-built RPM)

Hey gang -

Question: is there a way to query bgpd, zebra, etc to see if multipath 
was enabled when it was built?  I'm using the RHEL6 (CentOS 6) 
quagga-0.99.15-7.el6_3.2.x86_64 RPM, the kernel has both:

lateapex-gw# grep CONFIG_IP_ROUTE_MULTIPATH config-2.6.32-*
config-2.6.32-431.29.2.el6.x86_64:CONFIG_IP_ROUTE_MULTIPATH=y
lateapex-gw# grep CONFIG_IP_ADVANCED_ROUTER config-2.6.32-*
config-2.6.32-431.29.2.el6.x86_64:CONFIG_IP_ADVANCED_ROUTER=y

enabled.  However, two identical EBGP-learned routes, differing only in 
router-id, aren't being put into the forwarding table.  And I can't seem 
to figure out a way to enable EBGP multipath.  Is that even doable w/quagga?

lateapex-gw# show ip bgp summary

[quagga-users 13963] Quagga as router and ICMP redirect

Hi all.

I've a simple question.

Two quagga as bgp router (with VRRP), one linux host.

---BGP1-+---HOST
---BGP2-+

BGP1= IP 192.168.0.1
BGP2= IP 192.168.0.2
HOST= IP 192.168.0.5
VRRP(BGP1)= IP 192.168.0.254

BGP1 and BGP2 have different eBGP.
BGP1 and BGP2 are in iBGP with next-hop-self.

BGP1 and BGP2 have this sysctl:

 net.ipv4.conf.default.rp_filter=0
 net.ipv4.conf.all.rp_filter=0
 net.ipv4.ip_forward=1


The HOST use .254 (VRRP) as gateway.
When the route is know by BGP2 I receive ICMP redirect in reply from BGP1 to HOST.

My question is:

- Is it a good or bad solution keep active ICMP redirect with big traffic and many destinations known from BGP2?
- Can I disable ICMP redirect or this is a bad solution?

  Example:
  net.ipv4.conf.all.accept_redirects = 0
  net.ipv6.conf.all.accept_redirects = 0
H  net.ipv4.conf.all.send_redirects = 0

[quagga-users 13955] next-hop-self and "recursive is directly connected"

I have a problem with quagga recursively resolving routes when I have static
device routes. The following is the essential part of the (ibgp/65001) setup:

host1:
ip route add 10.0.0.254/32 (via 10.0.0.254) dev sfp0
network 10.0.0.1/32

host2:
ip route add 10.0.0.254/32 (via 10.0.0.254) dev sfp0
network 10.0.0.2/32

switch:
ip route add 10.0.0.1/32 (via 10.0.0.1) dev swp1
ip route add 10.0.0.2/32 (via 10.0.0.2) dev swp2
neighbor HOST peer-group
neighbor HOST route-reflector-client
neighbor HOST next-hop-self force
neighbor 10.0.0.1 peer-group HOST
neighbor 10.0.0.2 peer-group HOST

Problem:

On the hosts, I the routes (10.0.0.1/10.0.0.2) is installed, but like
device routes, and not with nexthop 10.0.0.254

Any way to change this behavior using configuration?

[quagga-users 13954] LSA type 5 filtering

Hello!

For some reason I need LSA type 5 filtering.
As far as I know cisco routers can do this, but , according to 
documnetation, Quagga ospf can only filter LSA Type3.
I even found reason for this in mailing list.

My problems are not urgent, but I need to force managements of two 
companies to talks with each other and confirm redesign,
or I need to have an ability to filter.

Could you tell me- are there any plans to implement Type 5 LSA filtering 
in Quagga?

Thank you!

[quagga-users 13953] Configuring LLDP with SNMP

Hi,

 

I am trying to configure LLDP with SNMP on Quagga ver 0.99.22.4 running on Centos 7.0.1406 this is in a Boeing CORE emulation.

I have just installed lldpd-0.7.13-1.1.x84_64 and I can start the lldpd daemon from Quagga node’s under Centos. But running a lldpctl doesn’t show any LLDP Neighbors up.

 

In vtysh there is no show lldp neighbors command so I am wondering if I have done something wrong or it’s not possible to do. Does anybody have this working?

 

Regards

Rob
