Hello,Let's say we have an NBMA network (e.g. Frame Relay) and we configure NBMA mode on it.I found in CBT Nuggets that there must be full-mesh connectivity in an NBMA mode in order to have IP communication between all routers.However, Cisco Student ...

if the ospf interface priorities tie, you then consider the routers' IDs. as i mentioned above, when the router ID is the criterion to choose a DR, you can to distinguish two cases: 1. if you did not configure any loopback address on the router, then...

i understood this:il a telnet traffic is going out serial 0, it will be allowed although it matches the first statement of the ACL. is that right?

first, there is no "dynamic" inverse ARP. inverse ARP is a dynamic method to map layer 3 addresses with frame relay DLCIs.with frame relay networks, inverse ARP is enabled by default on multipoint connections( and if you like on all F-R interfaces fo...

yep,i hope cisco systems will review their e-labs to avoid confusing ccna students
