  1. Hi Rene,

    Can i say that if i din't enable the soft-configuration for the neighbor, when i do clear ip bgp x.x.x.x soft in, it will not take any effects?

    Just clarify below is this correct?


    • Dynamic Soft Reset (route refresh) = clear ip bgp x.x.x.x soft in

    • Soft reset with pre-stored information = clear ip bgp x.x.x.x in

  2. Hi Davis,

    When you don't have soft configuration configured then that command will use the route refresh:

    R1#clear ip bgp 192.168.12.2 soft in

    Here's what you will see:

    R1#
    BGP: 192.168.12.2 sending REFRESH_REQ(5) for afi/safi: 1/1, refresh code is 0
    BGP: 192.168.12.2 rcv message type 5, length (excl. header) 4
    BGP: 192.168.12.2 rcvd REFRESH_REQ for afi/safi: 1/1, refresh code is 1
    BGP: 192.168.12.2 rcv message type 5, length (excl. header) 4
    BGP: 192.168.12.2 rcvd REFRESH_REQ for afi/safi: 1/1, refresh code is 2

    About the commands:


    • clear ip bgp x.x.x.x in: Soft reconfig inbound updates

    • clear ip bgp x.x.x.x out: Soft reconfig outbound updates

    • clear ip bgp x.x.x.x soft: Soft reconfig inbound + outbound updates

    • clear ip bgp x.x.x.x soft in: Soft reconfig inbound updates

    • clear ip bgp x.x.x.x soft out: Soft reconfig outbound updates

    When you don't have soft reconfiguration enabled, it will use a route refresh instead.

  3. Hi Rene,

    Looks there's no different clear ip bgp x.x.x.x soft in and clear ip bgp x.x.x.x in.

    Means both command works like below

    With Soft reconfiguration enable, both command will be use the existing table (before any policy apply) to apply the new policy if there is, without request from the neighbor

    without the soft reconfiguration enable, both command will be request the new routing table from the neighbor and apply the policy from here if there is.

    am i right?

  4. Hi Davis,

    That's right. It's a bit confusing but that's how it works yes.

  5. I think your sentence "We apply our inbound BGP policy to this information and the result is a table called the adj-RIB-in" should read "We apply our inbound BGP policy to this information and the result is a table called the Loc-RIB", correct? Also "seperate" should be "separate". (Sorry to be picky, I'm a spelling-bee champion wanna-bee.)
