OPEN Lab1

I. Logical Topology

IP Address:

Network x: 155.1.x.0/24

Loopback0 of all router is 150.1.y.y/24 (ex. R1  – 150.1.1.1/24)

II. Taks

1.  Frame Relay1.1  Hub-and-Spoke

  Configure a Frame Relay hub-and-spoke network between R1, R2, and R5 with R5 as the

hub.

  R1 and R4 should use their main interface.

  R5 should use a subinterface per the diagram.

http://slidepdf.com/reader/full/open-lab1 2/4

  Use only the DLCIs specified in the diagram.

  Do not use the frame-relay map command on R5.

  Ensure that R1 and R2 have IP reachability to each other.

1.2  Point-to-Point

 Configure a point-to-point Frame Relay circuit between R4 and R5.

  Use only the DLCIs specified in the diagram.

  Do not use the frame-relay map command on R5.

  Do not use Frame Relay Inverse-ARP.

2.  Interior Gateway Routing

2.1  OSPF

  Configure OSPF area 0 on the Frame Relay connection between R1, R2, and R5, and the

PPP links between R1 & R3, and R2 & R3.

  Advertise the Loopback 0 interfaces of R1, R2, R3, and R5 into OSPF area 0

  Do not use the neighbor command to accomplish this.  Do not use any interface level commands on R1 or R2 to accomplish this.

2.2  OSPF

  Configure OSPF area 137 on network 137 between R1, R3

2.3  OSPF

  Configure OSPF area 23 on network 23 between R2, R3, & SW2, and network 8 on

SW2.

  Advertise the Loopback 0 interfaces of SW1 and SW2 into the OSPF domain, but do not

use the network statement under the OSPF process to accomplish this.

2.4  EIGRP  Configure EIGRP 10 on R4, R5, R6, and SW1.

  Enable EIGRP on the Frame Relay segment between R4 and R5.

  Enable EIGRP on the Serial link between R4 and R5.

  Enable EIGRP on the fa link between Sw1 and R5.

  Advertise the Loopback 0 interfaces of R4, R6, SW1 into EIGRP.

2.5  IGP Redistribution

  Redistribute between OSPF and EIGRP on R5.

  In order to ensure optimal routing within the OSPF domain configure your network so

that routes redistributed in from EIGRP have a cumulative metric throughout theOSPF domain.

3.  IP Multicast

  Configure PIM Sparse-Mode on all transit interfaces between R1, R2, R3, R5, R4

3.1  Group 224.1.1.1

  Use R5’s Loopback0 interface as the static Rendezvous Point address for group 224.1.1.1

8/8/2019 Open LAB1

http://slidepdf.com/reader/full/open-lab1 3/4

  Configure Sw2 to join the group 224.1.1.1, and unsure that Sw1 can send multicast

packets to this group.

  Ensure that SW2 and R5 will only accept (*,G) joins toward R5’s Loopback0 for groups

224.1.1.1

3.2 

Group 224.4.4.4  Use R4’s Loopback0 interface as the static Rendezvous Point address for group 224.4.4.4

  Configure Sw2 to join the group 224.4.4.4, and unsure that Sw1 can send multicast

packets to this group.

Multicast Security

Ensure that SW2 and R5 will only accept (*,G) joins toward R5’s Loopback0 for groups

224.1.1.1

4.  Exterior Gateway Routing

4.1 BGP Peering

  Configure BGP on the following devices with the following AS numbers:

Device BGP AS

R1 200

R2 200

R3 300

R4 100

R5 100

Sw1 100

Sw2 300

  Configure the BGP peering sessions as follows:

Device Peers

R1 R2, R3, R5

R2 R1, Sw2, R5

R3 R1, Sw2

R4 R5R5 Sw1, R4, R1, R2

Sw1 R5

Sw2 R3, R2

4.2 BGP Filtering

http://slidepdf.com/reader/full/open-lab1 4/4

  Configure AS 100 so that it cannot be used as a transit AS for customers in AS 54 to

reach other ASs, and vice versa.

4.3 BGP Bestpath Selection

  Configure Sw2 with ten new loopback interfaces with the IP addresses 100.0.0.0/8---

110.0.0.0/8

  Use the local-preference in R1 so that traffic from AS 200 going to prefix 100.0.0.0/8 — 

105.0.0.0/8 in AS 300 via R3 and from AS200 going to frefix 106.0.0.0/8---110.0.0.0/8

via Sw2.

4.4 BGP Bestpath Selection

  Create a new loopback1 interface on both Sw1 and Sw2 with Ip add 1.2.3.4/32 and

advertise it into BGP on both Sw1, Sw2.

  Using just the MED attribute configure the network so that traffic from AS 200 going to

this prefix is always received by Sw1.

5.  IPv6 Tunneling

  Using the IPv4 Loopback0 interfaces create automatic 6to4 tunnels connecting R1, R2,

and R5.

  Create additional Loopback interfaces on every router with the subnet number zero and

the prefix length of 64 under the respective 6to4 /48 prefix.

  Use static routing to obtain connectivity between the newly allocated subnets.

6.  DHCP Relay

  Configure R5 to allocate IP addresses via DHCP to clients on network 40.

  The clients on network 40 should use R4 as the default gateway.
