CentOS - Dec 2009 - Quagga ECMP

Hello,

does anybody know if quagga for CentOS 5.3 is compiled with 
-enable-multipath?
I want to implement ECMP over 2 ISP.

Thanks,
Cristi Carstea

You can look in the /boot/config-* files. Those are the configs that
it was built with.  In my 5.4 system:

[root at xm-c32-001 boot]# grep -i multipath config-2.6.18-128.2.1.el5xen
CONFIG_IP_ROUTE_MULTIPATH=y
# CONFIG_IP_ROUTE_MULTIPATH_CACHED is not set
CONFIG_MD_MULTIPATH=m
CONFIG_DM_MULTIPATH=m
CONFIG_DM_MULTIPATH_EMC=m
CONFIG_DM_MULTIPATH_RDAC=m
CONFIG_DM_MULTIPATH_HP=m

yes, that's right, but i am asking here about Quagga, which is a routing 
software (OSPF, BGP etc.), not about kernel multipath, i mean if Quagga 
is compiled with Equal Cost MultiPath (ECMP), the "-enable-multipath" 
compile option. Can someone post here the spec file from which quagga 
rpm was built for CentOS? Thanks. On Thu, Dec 10, 2009 at 7:42 AM,

Looks like it. Spec file configure on my i386 box is:

+ ./configure --build=i686-redhat-linux-gnu --host=i686-redhat-linux-gnu
--target=i386-redhat-linux-gnu --program-prefix= --prefix=/usr
--exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin
--sysconfdir=/etc/quagga --datadir=/usr/share --includedir=/usr/include
--libdir=/usr/lib/quagga --libexecdir=/usr/libexec/quagga
--localstatedir=/var/run/quagga --sharedstatedir=/usr/com
--mandir=/usr/share/man --infodir=/usr/share/info --enable-ipv6
--enable-multipath=64 --enable-nssa --enable-opaque-lsa --enable-ospf-te
--enable-vtysh --enable-ospfclient=yes --enable-ospfapi=yes --with-libpam
--enable-user=quagga --enable-group=quagga --enable-vty-group=quaggavt
--enable-rtadv --enable-netlink

which matches the configure options at the top of the spec file:

# configure options
%define     with_snmp   0
%define     with_vtysh  1
%define     with_ospf_te    1
%define     with_nssa   1
%define     with_opaque_lsa 1
%define     with_tcp_zebra  0
%define     with_pam    1
%define     with_ipv6   1
%define     with_ospfclient 1
%define     with_ospfapi    1
%define     with_rtadv      1
%define     with_multipath  64
%define     quagga_uid      92
%define     quagga_gid      92
%define     quagga_user quagga
%define     vty_group   quaggavt
%define     vty_gid     85
