Free Cisco Lab Scenario Advanced BGP

Posted by: admin  :  Category: BGP, CCIE, CCNP, EIGRP, IGRP, OSPF, RIP


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. 


  • 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 and
  • Configure router R7’s Ethernet 0 interface with address
  • Configure BGP on Router R7 with AS number of 200, and set it up to advertise the three networks. (,,
  • 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 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 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

    Commonly i tend not to react to a article just like that, although considering that i really loved it I just must give you the thumbs up 🙂

    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.
