Advertising Static route Discard via BGP showing as hidden

  • 1.  Advertising Static route Discard via BGP showing as hidden

    Posted 08-05-2021 16:16
    Hi,

    I have a requirement where I need to create a source NAT pool where the addresses/prefixes are not built on any interfaces. I then need to advertise this NAT pool via BGP to an adjacent SRX4600.

    To get around this I have created a static route with next-hop discard to install the route in the table. I then add the NAT pool network to a policy statement and apply this to the BGP peer export list.

    The problem is on the adjacent SRX4600 the NAT pool route only shows when running show route receive-protocol bgp hidden. Why is this route showing as hidden and what could be the workaround so it appears as an active route?

    If this is an iBGP session you might need to add the next hop self to the policy for the advertisement.

    You will need to create a Policy Statement for the addresses/prefixes to be received on the SRX4600 for it to be an active route. And then you import the policy statement into the BGP Protocol.

    If this eBGP, you might need to create a Policy Statement for the addresses/prefixes to be received on the SRX4600 for it to be an active route. And then you import the policy statement into the BGP Protocol at SRX4600.
