- OSPF–> DR / BDR, ISA types, states, messages, same router id.
- BFD why is it req, modes.
- What is difference between multilayer switch and normal l2 switch.
- Can we connect 1000 routers in same OSPF area (not recommended max is 40).
- Can we connect different capacity platform in same area of OSPF.
- If I connect 265 routers back to back and all configs are correct then also ping is not reachable to end node.
- ICMP reply with Destination not reachable and time out what is difference.
