  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

    You are 100% correct, just fixed these errors. Thanks!

  4. Hi Rene and Team,

    Is the adj-RIB-In-In table for each neighbor static, as in it doesn’t dynamically update once it is initially populated when neighbor first comes up?

    If we want to repopulate the adj-RIB-In can this only be done with a hard reset?

    Thanks

  5. Hello Robert

    The adj-RIB-In table will not be refreshed when using a soft reset. The table is static only in the sense that it will not change when implementing a soft reset. But this table isn’t static in general. If there are changes to routing that BGP neighbours send to the local router, these will go into the adj-RIB-In table and be updated.

    A hard reset will repopulate the adj-RIB-In table, however, like Rene mentions, it is not preferred. If the router in question supports it, the most preferred method is the Dynamic Soft Reset option also known as R
