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.

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

[root@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
