VLSM RIPv2 EIGRP OSPF Inter-AS routing VLAN VTP Inter-VLAN routing

VLSM • Supply IP address as required by each subnet or network, keep in mind of future scalation. • If it is possible, IP addressing scheme should favor address summarization

RIP • What are the differences between RIPv1 and RIPv2?

OSPF • • • •

OSPF terminologies OSPF process OSPF tables OSPF configuration (network, authentication, default route) • OSPF verification (show, debug) • OSPF troubleshooting

EIGRP • • • • • •

EIGRP tables Building and maintaining EIGRP routing table EIGRP packet types EIGRP configuration (network, summarization) Verifying EIGRP (show, debug) Troubleshooting EIGRP

Inter-AS routing • Automatic redistribution • Redistribution with subnets • Redistribution with default metric

VLAN • • • • • •

Switch default settings VLAN definition and assignment Restore switch default configuration Trunking switches Switch IP assignment Troubleshooting

VTP • •

Reset all switches to factory default On VTP server: – Set VTP domain name and password(if required) – Create VLANs – Create trunk port connecting to client

•

On VTP client: – Set to VTP client mode – Set VTP domain name (not necessary) – Create trunk port connecting to server

• • •

Verify VTP operation Assign VLAN to port on both VTP server and client Other switch configurations

Teamwork • Elect a team leader, someone knowledgeable, organized and knows others’ abilities • It is best that members can do everything but it is better to assign the job the the right member. • Organizing is important, the leader must keep others focus, on time and in order • Plan first then execute

Teamwork • Problem of starting maybe time-consuming but can be avoided if organized well. • 1st member draw topology and parameters on the board • 2nd member checks the physical wiring and provide information for 1st member • 3rd member runs the console or ethernet cable (including checking connection, erase old config) • 4th and 5th members deal with IP, IPX scheme and assignment as well as other relating issues

Consolidation Lab Topology(6)

• • • • • • • •

Each Ethernet network requires 30 IPs Configure names, passwords, descriptions and banners for routers SW1 is Server, SW2 is Client, VTP domain Open, password Lab with 3 Vlan named: Sale, Marketing, Accouting. Create 3 Vlan named: Remote, Small on SW3. Set IPs for SWes. Inter-VLAN routing for all 4 VLANs on E1 and 3 on Gate. Redistribute routes between the 2 area with default metric Only nodes in VLAN Remote are allowed to telnet to O1 and O2 Do not allow any SW3’s VLAN to access E2 by web Do not allow ftp and tftp traffic between 2 areas.
