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,

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
