Hello Group,
I am trying to understand BGP Notes from 911networks.com. I did not
understand the below points or how to do it . If possible, can you
explain me how to solve it ?
Statement 1:
---------------
The ospf router-id must be the same as the bgp router-id for
redistributing the routes from ospf to bgp. It needs to be done
manually if a route-reflector is involved or it won't work.
Question 1:
----------------
ex: R1---------R2 (RR)------R3
Should i change the router-id of incoming ospf updates on R3 ? or
should i change Bgp router-id on R3 ? Any examples.
Closest i found from searching is below, but could not benefit.

Statement 2:
--------------
The BGP Router-id is used with the synchronization and in iBGP the BGP
Router-id is used as tie breaker for the BGP path selection
* Just because the next hop is pingable, it does not mean it's a
valid next hop.
* Next hop addresses that are reachable only via a default route
aren't valid.
* Next hop addresses that are reachable only via another BGP route
are also not valid.
Question 2:
---------------
I thought, if there is a problem with nexthop, route will not be
available in BGP routing table right ?
