パッチの代わりにソースiproute（2.6.32.130）を取得する方法

以下のパッケージのソースを見たいです。

[root@ovs-1 ~]# rpm -qa | grep iproute
iproute-2.6.32-130.el6ost.netns.3.x86_64

以下のようにsrc rpmをインストールしようとすると、次のエラーが表示されます。

[root@ovs-1 ~]# ls
iproute-2.6.32-130.el6ost.netns.3.src.rpm  rpmbuild
[root@ovs-1 ~]# yum install iproute-2.6.32-130.el6ost.netns.3.src.rpm

Cannot add package iproute-2.6.32-130.el6ost.netns.3.src.rpm to transaction. Not a compatible architecture: src
Error: Nothing to do

rpmを使用してインストールしようとすると、複数のパッチがインストールされます。完全なソースコードを見たいです。どうすればいいですか？
