By default, routing loop detection is enabled on CE switches. When OSPF VPN multi-instance is deployed on a Multi-VPN-Instance CE (MCE) device, and DN Bit is set in Type 3, Type 5, or Type 7 LSAs, corresponding routes cannot be calcula...

where another route a.b.c.d/16 sourced from C as well does make it into the database and is then injected into the routing table for site B. I have confirmed that my ACLs used for redistribution are correct, in fact the ACLs show matches for both routes mentio...
A. No, OSPF does not work if you have one side numbered and the other side unnumbered. This creates a discrepancy in the OSPF database that prevents routes from being installed in the routing table. Q. Why do I receive the cannot allocate router id error message when I configure Router ...
What is role of topology and routing table in OSPF ? When I issue the “show ip ospf neighbor” command, why do I only see FULL/DR and FULL/BDR, with all other neighbors showing 2-WAY/DROTHER ? Name types of LSA ? Why do I receive the “cannot allocate router id” error message ...
How do I stop individual interfaces from developing adjacencies in an OSPF network?When I have two type 5 link−state advertisements (LSAs) for the same external networkin the OSPF database, which path should be installed in the IP routing table?
And now it shows up in the routing table of R2. Lesson learned: You can not advertise what you don’t have! OSPF Distribute-List Next issue! Same two routers: Single area, same 2 routers…we would like to have “full connectivity” but something is off…here is the output of the ro...
One way to verify if VRF-Lite is configured is by checking it the ospf process is showing as not connected to MPLS Superbackbone. When you enter this command on a PE device, along with disabling the loop prevention checks, it will also not resemble OSPF routes to LSA 3, but only redist...
Dynamic Routing – What is the difference between routing table and forwarding table? Routing tables contain network addresses and the associated interface or nexthop. This refers to ip route and ip rule (in a Linux context). Forwarding refers to packets which reach a system but are not destine...
