[Xorp-users] BGP not advertising our route?

[Atanu Ghosh]

Hi,

You need to explicity announce your own address space via policy.

----------------------------------------
protocols {
    static {
       route 138.236.0.0/16 {
           next-hop: 216.114.193.145
           metric: 1
      }
   }
}

policy {
    policy-statement static {
        term export {
            from {
                protocol: "static"
            }
        }
   }
}

protocols {
    bgp {
	export: "static"
	/* Rest of your config below */
	...
    }
}
----------------------------------------

Something like the above should work.
