Hi All,
My company has a Hub and Spoke topology, and 26 routers in the HQ and another two DR sites.
We are running OSPF and BGP in our enterprise but we also have many ACL, static route and PBR.
Unfortunately, we do not have good documentation. So when we have the ticket from the help desk (like Host A cannot reach out B).
I have to traceroute the IP address and login every hop (most of the hop is router and switch) to check the routing table and ACL.
Can somebody please share the way that can find which router blocked the traffic very quickly?
Thanks,
Yiwei

- As you state traceroute will give you an initial idea , as to who blocks the path from A to B , but if you have all those elements in place, such as PBR, Acl's, routing, OSPF and BGP then it becomes more then time to have the network managed in an orderly and by knowledge methodologies.
