This document discusses configuring basic network address translation (NAT) in an ASA firewall. It describes configuring three interfaces: outside, inside, and DMZ. It also describes configuring static routes and default routes between the ASA and three routers. The document then explains different NAT configuration options in the ASA including dynamic NAT, static NAT, NAT exemption, identity NAT, NAT overload, and static PAT.
IS-IS (Intermediate System to Intermediate System) Protocol uses NSAP (Network Service Access Point) addresses instead of IP addresses. NSAP addresses consist of an area address, system ID, and N-selector. The area address contains an AFI, IDI, and HODSP. NSAP addresses can also be divided into an interdomain part containing an AFI and IDI, and a domain-specific part containing HODSP, system ID, and NSEL. IS-IS uses different multicast addresses for L1 and L2 updates depending on the network type.
OSPF authentication prevents unauthorized routing updates by authenticating packets between routers. There are two authentication methods: plain text uses a clear text password in packet headers, while MD5 uses an encrypted hash. The document provides configuration examples for authenticating a connection between HQ and BRANCH routers using each method, and verification commands to confirm authentication is enabled.

In this session, the focus will be on OWASP Top 10 mobile risks and prevention tips. Hackers’ exploitation of these most common mobile vulnerabilities will be demonstrated in the session.
BGP is an inter-autonomous system routing protocol that exchanges routing and reachability information between autonomous systems on the internet. It allows traffic to be rerouted to alternate paths if the primary route fails. BGP uses TCP port 179 to send triggered updates when there are changes in the network and maintains routing tables to track routes from multiple autonomous systems to determine the best paths. However, receiving full routing tables from multiple ISPs can require significant memory and resources for routers.
VLAN allows logical separation of broadcast domains by tagging Ethernet frames with VLAN IDs. It divides a physical network into virtual LANs to improve security, manageability and flexibility. VLAN configuration involves assigning ports to VLANs either statically by port number or dynamically by MAC address. Frame tagging standards like IEEE 802.1Q are used to identify VLANs on trunk links that carry traffic for multiple VLANs between switches.
BGP uses the AS path attribute to prevent routing loops. When a route passes through multiple autonomous systems (AS), each AS prepends its AS number to the AS path. Routers will ignore any updates containing their own AS number in the path to avoid loops. This is demonstrated by enabling debugging on R2 - it rejects an update from R4 containing its own AS 65003 in the path. IBGP within an AS also prevents loops through the split horizon rule and a full mesh of IBGP sessions.
- By default, EIGRP has auto summarization enabled which summarizes routes to classful boundaries, but this can cause issues, so EIGRP allows manual summarization at arbitrary boundaries using the ip summary-address command.
- Manual summarization can be configured on any router or interface in an EIGRP domain. A summary route will exist as long as there is at least one more specific route; if the last specific route disappears, the summary will also disappear.
- The document provides an example configuration of EIGRP routing between four routers (R1, R2, R3, R4) with the configuration of manual summarization on R2's S0/0 interface to summarize routes
The document provides steps to recover the password on a Cisco Catalyst 3850 switch. The steps are: 1) power off the switch and hold the mode button for 12 seconds to boot to the ROMMON prompt, 2) enter commands to ignore the startup config and reboot, 3) copy the startup config to running to restore configuration, 4) add a new user or change the enable secret, and 5) save the configuration and reload the switch.
