    I was looking over one of our routers and found this static routing-option

    route {
    community 16832:64516;

    This is one of our IP blocks from ARIN and I was wondering if this static route is set up to prevent our IP's from being re-advertised into our network? This is how I interrupted this static route. We are about to add a new IP block we acquired from another small ISP and since it will be assigned to our AS I thought I would have to create a static route like this for the new block.  Am I understanding this correctly? Thank you

    Having a static discard route with a community attached is most likely setup so that the route is created specifically for distribution into BGP peerings.

    Take a look at the export policies in place on this device and a term will likely be there looking for the community.

    The community will probably be configured with a name under
    policy-options community NAME 16832:64516

    That community NAME will then be used in bgp policy to choose what to do with these routes during import or export operations.

    Adding a second route with this same community will likely then be treated the same way as the existing route in bgp policy.
