Pavlin,

Now that XORP CVS runs again, I'm retrying to use click and before
writing my own config files, I'd like to run yours successfully (the one
you gave in a previous email).  What I'm facing is that I can't have a
xorp configuration that is both xorp and click compatible.

My configuration is like this currently :
interfaces {
    interface eth0 {
        description: "control interface"
        vif eth0 {
            address 10.2.0.4 {
                prefix-length: 24
                broadcast: 10.255.255.255
            }
        }
	mac: 1:1:1:1:1:1
	mtu: 1500
    }

    interface eth1 {
        description: "control interface"
        vif eth1 {
            address 10.7.0.1 {
                prefix-length: 24
                broadcast: 10.255.255.255
            }
        }
	mac: 2:2:2:2:2:2
	mtu: 1500
    }

}

fea {
    enable-unicast-forwarding4: true
    /* enable-unicast-forwarding6: true */

    click {
        enabled: true
        click-config-generator-file:
"/home/xbr/intel/fea/xorp_fea_click_config_generator"

        kernel-click {
            enabled: false
            install-on-startup: false
            kernel-click-modules:
"/path/to/proclikefs.o:/path/to/click.o"
            mount-directory: "/click"
        }

        user-click {
            enabled: true
            command-file: "/home/xbr/intel/bin/click"
            command-extra-arguments: "-R -p 13000"
            command-execute-on-startup: true
            control-address: 127.0.0.1
            control-socket-port: 13000
            startup-config-file: "/dev/null"
        }
    }
}

protocols {
    static {
        route4 10.10.0.0/16 {
            nexthop: 10.2.0.2
        }

        route4 10.20.0.0/16 {
            nexthop: 10.7.0.7
        }

    }
}

The difference with yours are :
- I use user-click instead of kernel-click
- I added the mtu and mac in both interfaces sections

xorp_fea_click_config_generator processes this configuration nicely and
gives a correct click configuration. =20

However, when I run "xorp_rtrmgr -b config.xorp", XORP doesn't like the
new mtu and mac syntax and I get :
[ 2004/12/15 13:43:28  ERROR xorp_rtrmgr:206 RTRMGR +357 main_rtrmgr.cc
run ] rtrmgr shutting down due to an init error: PARSE ERROR [Config
File /hosthome/config.xorp, line 10]: syntax error; Last symbol parsed
was "10.255.255.255"

I can't remove the mtu and mac, else xorp_fea_click_config_generator
will complain...

What's the trick ?

Thanks,
