ISCW Hotspot: EIGRP over GRE Tunnels

Topology:



Q1. What is the reason for the ping failure between the CiscoSims-HQ router and the 192.168.1 193 interface on the Branch2 router?

A. The default route is missing from the Branch2 router.
B. When running EIGRP over GRE tunnels, you must manually configure the neighbor address using the eigrp neighbor ipaddress command.
C. The tunnel numbers for the tunnel between the HQ router and the Branch2 router do not match.
D. The tunnel source is incorrect on the Branch2 router. It should be serial 2/0.
E. The AS number for the EIGRP process on Branch2 should be 1 and not 11.


Explanations:-

Branch2#sh run
HQ#sh run



- The default route of Branch2 is normal and points at the outbound GRE-channel can be used to deliver dynamic routing information and no special configuration is necessary for routing protocols. The exhibit shows that the tunnel source of Branch2 is serial2/0. So as to enable route delivery, the AS number of EIGRP must be the same in the whole EIGRP area. So we choose E.

BCMSN Lab - Spanning Tree

Scenario:
Acme is a small export company that has an existing enterprise network comprised of 5 switches; CORE,DSW1,DSW2,ASW1 and ASW2. The topology diagram indicates their desired per-VLAN spanning tree mapping.


Previous configuration atempts have resulted in the following issues:

BCMSN Hotspot: Spanning Tree

Scenario:
CiscoSims is an Internet game provider. The game service network had recently added an additional switch block with multiple VLANs configured. Unfortunately, system administrators neglected to document the spanning tree topology during configuration. For baseline purpose, you will be required to identify the spanning-tree topology for the switch block.

Scenario:-
You are a network support specialist for CiscoSims, an IT training firm. They have just installed a new router(R1) in to their network. The router was successfully installed and is passing traffic. However, your manager is concerned about security and has tasked you with implementing access security for the new router R1.
