Advertise NAT pools to BGP [ Edited ]

[EA]

NAT Pools:

1.1.1.0/24

2.2.2.0/24

3.3.3.0/24

SRX has interface in only one of these networks (1.1.1.1) with a BGP peer at 1.1.1.254.

Since 1.1.1.0/24 is active in our routing table, no problem getting that into our BGP advertisement.

What is the most appropriate way to inject the 2.2.2.0/24 and 3.3.3.0/24 NAT pools into BGP?

Static route with discard action? Static route with receive action? Other?

My standard method is to create a discard static route and use that for the BGP export.

There are other methods. Choose one you like best. I like discard, it's worked well for me.

Like this:

routing-options {
    static {
        route 2.0.0.0/24 discard;

  }

}

policy-options {
    policy-statement public-to-bgp {
        from {
            protocol static;
            route-filter 2.0.0.0/24 exact;
        }
        then accept;
    }
}

protocols {
    bgp {
        export public-to-bgp;

  }

}

That works. I guess the NAT process grabs it before it actually discards it. It seemed to work that way but it felt counter-intuitive to tell it to discard traffic destined for a network for which I wanted to receive traffic. Thanks for the reply.
