  1. Awesome work Rene!!!

  2. Rene,

    on router 4 you type a "show ip bgp" and say that the "router will install the OSPF (AD 110) entry for 1.1.1.0/24
    instead of IBGP (AD 200) route"

    router 4's BGP table says that LocPrf is 100. did you mean t6o say ad 100 and not ad110 ? if i have this wrong can you explain what the "LocPrf" as I think that it means the local preference of iBGP AS2

    thank you

  3. Hi @chriscowboyfann,

    I didn't watch the video again but if I was talking about the AD, it's 110 for OSPF. If the router has to decide if it wants to use routing information from routing protocol X or Y then it will look for the AD. For example, 1.1.1.0/24 is learned through IBGP and OSPF...t will look at the administrative distance and prefers the lowest value. It will use OSPF since it has an AD of 110, compared to 200 for iBGP.

    The local preference is used when the router has learned multiple paths for a network through BGP, and it has to make a decision which path to use. The default local preference value is 100. Here's an example btw:

  4. Hey Rene, I don't quite understand how your BGP table can show RIB Failure in sub-section "BGP synchronization disabled" for R4's route to 1.1.1.0, you have no IGP providing route to it, how can it be in RIB failure ?
