interface GigabitEthernet4/1 ip address 10.195.48.53 255.255.255.240 Notice the IP address of this interface. OSPF 499 is running OSPF on this interface (see the network statement), yet the interface is un-passived out in OSPF599...why is that? Typos? Thanks 1 person had this problem ...
If no loopback interface is configured, the router selects the largest IP address among other interface addresses as its router ID. After the router has been running OSPF and selected its router ID, it still uses this router ID if the interface whose IP address is used as the router ID ...

After the router has been running OSPF and selected its router ID, it still uses this router ID if the interface whose IP address is used as the router ID is Down or disappears (for example, theundo interface loopbackloopback-numbercommand is run) or a larger interface IP address exists....
This interface configuration command assigns the OSPF priority to an interface. Different interfaces on a router may be assigned different values. The default priority is 1. The range is from 0 to 255. 0 means the router cannot be the DR or BDR. A router that is not the DR or BDR ...
If you select the interface, the system can prevent you from changing the address on the interface because it is used in the routing process. This helps remind you that any change to interface addressing can impact your routing configuration. If you select an interface here, before you ca...
If the receiving interface sees its own router ID in this list, then bidirectional communication has been established between the two interfaces. OSPFv2 uses Hello packets as a keepalive message to determine if a neighbor is still communicating. If a...
Oh, all right, I know this is confusing Let me explain. First of all, I was wrong in the assessment that OSPF will treat the GRE multipoint tunnel interface as a NBMA interface. While the GRE multipoint interface is technically a NBMA network, OSPF still considers the multipoint tunnel ...
The role of a router is subnet (or interface) specific. It might be a DR on one interface and a BDR or DROther on another interface.In Figure 7, solid lines are Ethernet physical links, and dashed lines represent OSPF adjacencies. With the DR and BDR, only seven adjacencies are ...
