BGP Synchronization

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:
