Goals & Restrictions

1. Advertise loopback with their original mask. (X= Rack no, Y=Device no)

a. Use 200.200.200.XY/32 for all loopback 0 in all routers

b. -

2. Network 0.0.0.0/0 SHALL not appear in any routing table

3. Dont use ip default network

4. All IP Address used in the topology MUST be accessible

5. Use conventional routing algorithms

Undebug all; Document your findings

Change frame relay encapsulation to IETF ( with & without no frame-relay

inverse-arp)

DO all above show commands in all 3 routers:

Debug frame packet; reset frame interface; capture successful frame packets

exchange;

Undebug all; Document your findings

Configure compression in R1 frame relay circuit with stac algorithm

o show interfaces serial

o clear compress

o show compress

o debug compress

STEP 2 R6 only

Configure the frame relay configuration in router R6.

NO need to configure BB1.

Use point-to-point sub-interfaces in R6.

PING ALL 3 subnets BB1 IP address from R6

DO all show commands

Debug frame packet; reset frame interface; capture successful frame packets

exchange;

Undebug all

STEP 3

Shutdown frame-relay DTE interface from all the previous configurations

Configure the NEW frame relay configuration as the above diagram.

o Full Mesh Frame Relay Topology

o Hub & spoke partial mesh topology

o You only need to configure Frame-relay DTE

DO NOT use any subinterfaces in any routers

Use Static route only.

o Use specific static route that required only.

Do below show commands in all 4 routers:

o Show frame-relay pvc

o Show frame-relay lmi

o Show frame route

o Show frame map

o Show interface serial ______

PING all the IP address from anyway including the loopback IPs.

STEP 4

Re-Configure the frame relay configuration as the above diagram.

o Full Mesh Frame Relay Topology

o Hub & spoke partial mesh topology

Use Subinterfaces in R1 & R2 only.

Re-Use Static routes only.

o Re-use specific static route that required only.

Do below show commands in all 4 routers:

o Show frame-relay pvc

o Show frame-relay lmi

o Show frame route

o Show frame map

o Show interface serial ______

PING all the IP address from anyway including the loopback IPs.

STEP 5

Document your observation

Answer below Questions:1. What is size of DLCI field in Frame-relay Header ? __________ bits

2. What is the purpose of DLCI field ?

3. Type of LMIs

a. Ciscob. Ansic. Q933a

4. An interface is by default a "multipoint" or point-to-point interface ?

5. In Multi-point interface is frame-relay inverse-arp is ON or OFF ?

6. In Point-to-point interface, is there is Inverse ARP used?

7. You can configure Frame Relay subinterfaces in point-to-point mode only

(TRUE or FALSE)

8. IP split horizon checking is enabled or disabled by default for Frame Relayencapsulation?

9. When remote router does not support Inverse ARP, you must define theaddress-to-DLCI table statically. (TRUE or FALSE)

10.Multipoint subinterfaces act like NBMA networks, as such they (do or donot?) resolve the split-horizon issues.

11.Multipoint interface require configuration of multiple subnets

12.Multipoint is applicable to point-to-point , partial mesh and full meshtopologies. (TRUE/FALSE)

13.Describe meanings of dynamic, broadcast , active ?Router#show frame-relay mapSerial0 (up): ip 3.1.3.2 dlci 140(0x8C,0x20C0), dynamic, broadcast,, status defined, active
