Free Cisco Lab

Overview:

In this lab scenario there are two BGP AS in addition to OSPF, EIGRP, IGRP and RIP routing protocols. This is a timed lab much like that of a CCIE lab. Nine  hours have been allotted to complete the lab scenario Good Luck. 

Preparation:

• Turn off DNS lookup on all the routers
• Disable console timeout on all the routers
• Do not use static routes
• Use Class C 192.168.100.x for network addressing

Topology and IP address setup (0.5 hour)

• Configure Catalyst switch so that port 2/1, 2/3, 2/4 and 2/5 are each on a separate VLAN
• Address vlan1 to have 14 hosts
• Address vlan2 to have 31 hosts
• Address vlan3 to have 6 hosts
• Address vlan4 to have 6 hosts
• Address R2 token ring to have 14 hosts
• Address R4 token ring to have 6 hosts
• Create three loopback interfaces on R3, using 30 bit mask
• Setup the serial link between R1 and R2 as 64K back to back link using HDLC encapsulation and with 28 bit mask
• Setup the serial link between R4 and R5 as 64K back to back link using PPP encapsulation with 30 bit mask
• Verify that you have a working IP setup by pinging the local interfaces on each router.

Configure Frame-Relay Switch (0.5 hour)

• Configure the Frame Relay switch according to the diagram
• Use LMI type Cisco and encapsulation IETF
• All ports on Frame-Relay switch are DCE
• Set the Frame-Relay speed to 64K
• Use 28 bit subnet mask to address the Frame-Relay network
• Use sub-interfaces on Router R3 and R5, use “frame-relay map” statement on R1
• Confirm connectivity by pinging from R1 to R3 and R5

Configure IP across the ISDN link (1 hour)

• ISDN switch type is NI-1
• For ISDN port connected to R1:        SPID1: 0835866201, DN 835-8662

SPID2: 0835866401, DN 835-8664

• For ISDN port connected to R3:        SPID1:            0835866101, DN 835-8661

SPID2: 0835866301, DN 835-8663

• Using a 28 bit subnet mask, configure the ISDN link such that traffic from R3 to R1 will force the ISDN line to dial, but not vice-versa.
• Confirm IP connectivity across the ISDN link by pinging from R3 to R1.

  OSPF Configuration (2 hours)

• Configure OSPF according to the diagram.
• Use OSPF MD5 authentication between R1 and R3, set MD5 password as “cisco”
• Ensure that R3 can still see all the routes.
• Configure R3 so that the ISDN line will come up if the frame relay connection fails.

IGRP (0.5 hour)

• Configure IGRP on R2 token ring and serial interface S0.
• Configure IGRP on R1 serial interface S1.
• Make sure those are the only interfaces advertising IGRP.
• Redistribute between OSPF and IGRP on R1.
• Make sure R2 can Ping all interfaces in the OSPF domain.

RIP (0.5 hour)

• Configure RIP on R1’s E0.
• Make sure this is the only interface advertising RIP
• Redistribute between OSPF and RIP on R1.
• Verify R4 can Ping R1’s Ethernet 0 interface.

BGP (3 hours)

• Configure 2 loopback interfaces on Router R7 using the network address 10.0.0.1/8 and 172.16.0.1/16.
• Configure router R7’s Ethernet 0 interface with address 11.1.1.2/24
• Configure BGP on Router R7 with AS number of 200, and set it up to advertise the three networks. (10.0.0.0, 172.16.0.0, 11.1.1.0)
• Configure External BGP on R2 using AS 100. Configure the BGP between router R7 and Router R2 so that R2 can see all three interfaces configured on Router R7.
• “show ip route” and “show ip bgp” on Router R2 should show the three networks advertised by Router R7.
• Configure BGP on Router R1, R3, R4 and R5 using AS 100.
• Make Router R1 a route-reflector neighboring with R3, R5 and R4.
• Do not redistribute between BGP and OSPF, RIP or IGRP
• A “show ip bgp” and “show ip route” on Router R3 should show the three routes advertised by router R7.
• Configure a filter on Router R2 that will prevent network 11.1.1.0 from advertising into the AS 100.
• Configure EBGP on router R4 with AS 100 neighboring with R7.
• Configure BGP on R4 so that it will be the preferred exit to network 10.0.0.0 on router R7
• Configure BGP on R2 so that it will be the preferred entry point for traffic from R7 destined for EIGRP loopback interface.

IP Firewall (1 hour)

Configure an inbound access-list on R2’s Serial0 interface that meets the following: 

• Telnet is permitted if originated from R5
• FTP is permitted if originated from VLAN3
• TFTP is permitted
• SMTP is not allowed
• WWW is not allowed from VLAN1, but is allowed if originated from VLAN3
• PING is permitted from everywhere

   a few of my favorites, since I was here There is some stuff. Well this is also an. I need it one of my school projects, fortunately for me mine is on a similar theme as the one here. Glad, happy trails.
