TASKS
1. Configure IP Addresses on each link.
2. Configure Loopback address 100.100.100.1 on AS1Destination, 20.20.20.1 on A2, 70.70.70.1 on R7, 80.80.80.1 on R8 and 90.90.90.1 on R9.
3. Configure eigrp 50 on network 1.1.1.0/24, 2.2.2.0, 3.3.3.0, 4.4.4.0
4. Configure eigrp 100 for network 6.6.6.0 and 5.5.5.0.
5. Configure RIP on 7.7.7.0.
6. R6 should reach R8 loopbacks without any dynamic routing protocol.
7. Configure un-equal load balancing for AS1Destination on A2. Network 1.1.1.0 is a successor route. Put Feasable successor in the routing table too.
8. full network should reach each other with only exception of network 8.8.8.0; It should only be seen in R6 routing table only. Don't filter network 8.8.8.0 anywhere in network.
9. Eigrp shoul use only 30% bandwidth btw R7 and R6
10. R6 should Send summary route of network 1.1.1.0/24 to R7. Try to on output as summary network has different AD then non-summary network.
11. See Routing table and topology table on A3 and find equal-cost LB for net 20.20.20.1.
12. Debug all kind of packets. See Ack packet by shutting/no-shut an interface
13. Manipulate Eigrp Metric ( metric weight TOS value, K1, K2, K3, K4, K5). Change value other then 0 and 1 and see results
14. Change Administratice distance (distane Internal-AD   External-AD)
15. Change bandwidth and Delay on interfaces
16. Change Eigrp utilization on interface via (ip band-perc eigrp 50 20)
17. Make sure that Eigrp uses 246 Kbps on R7 F0/0 but without using ip band-percentage command. [hint: Make actual bandwidth 1024 as by default Eigrp uses 50% bandwidth]
18. change Max hops of Eigrp (Metric Max-hop number)
19. Calculate EIGRP Metric by yourself

Explanation

Frame Relay over MPLS (FRoMPLS) Scenerio

11/26/2013

 
Frame Relay is a private networking technology similar to the concept of MPLS in that it is delivered in the “cloud”. Frame Relay can run over MPLS to obtain the benefits of traffic prioritization and management. Frame Relay has no quality of service (QoS) manageability and is largely being replaced by the more cost effective MPLS VPN Solutions.


MPLS is a protocol that uses packet labels to prioritize network packets to optimize network performance. If you have Quality of Service (QoS) sensitive applications such as VoIP, video conferencing, SAP, Oracle, Citrix or other real time applications running across your WAN then you should consider MPLS.
Picture
Requirement:
Configure IP address as per topology
CE1 should communicate to all mpls cloud via mpls
FRS1 should communicate to FRS2 and FRS3 via FROMPLS
There should not be any communication between FRS2 and FRS3

Configuration Explanation

Cisco's Express Forwarding (CEF) is an Layer 3 fastest switching technology by which Cisco router forwards packets from ingress to egress interfaces.
Note: This is a essential command

Globally enabling MPLS forwarding does not enable it on the router interfaces. You must enable MPLS forwarding on the interfaces as well as for the router.

Enable LDP protocol globally. MPLS Label Distribution Protocol (LDP) enables peer label switch routers (LSRs) in an MPLS network to exchange label binding information for supporting hop-by-hop forwarding in an MPLS network


Enabling interface with IP address



Enabling interface with IP address

Enabling MPLS LDP on interface
Enable Mpls IP on interface


Configuring OSPF for two networks



Default route



















































































command will enable your router to act as frame relay switch


Loopback interface ip. We are using this to enable our FR over MPLS communication through connect and xconnect commands given below




























In previous releases of AToM, the command used to configure AToM circuits was mpls l2 transport route. This command has been replaced with the xconnect command.

Applied command is telling to connect DLCI 301 and transport it via serial 0/0

The xconnect command is not supported on Frame Relay interfaces directly. For Frame Relay, the Xconnect is applied under the connectcommand specifying the DLCI to be used. we would directly apply xconnect directly to the customer interface, i.e under an ethernet interface or when the encapsulation is PPP or HDLC on a serial link. Frame relay encapsulation requires an alternate configuration.

command is telling to connect to router-id 13.13.13.13 having virtual circuit 20 using encapsulation type mpls

Enforcing MPLS router ID to be loopback 0 ip address. This will break LDP neighbor relationship and reestablish it

Configure routers so that R2 will be the default router for whole network and it will originate default information to whole network but only on speciified interfaces.

RIP Metric Manipulation by Offset list

9/24/2013

 
Tasks:
Configure ip addresses as per topology
Configure Rip on all networks
R3 will forward all routes to R5 by adding 10 in metric except network 1.1.1.0
R1 will change metric for 4.4.4.0 to 5 for R4 and 8 for R2
Verify results by:

Floating Static Route

9/18/2013

 
TASKS:
  1. Configure IP addresses on R1 and R2 as per topology
  2. Configure Loopback interface on R2 10.1.1.1/32
  3. Configure 1.1.1.0 as primary static route
  4. Configure 1.1.2.0 as floating static route
  5. Verify results by shutting down primary route interface of R1, R2 and both.

OSPF Area Range for Border Routers

9/2/2013

 
Picture
TASKS:
1. Configure IP Addresses as per diagram
2. Configure 5 subnet of 20.0.0.0/8 as loopback addresses in R3
3. Look into routing table inter-area routes
4. Configure Area Range command on R2 and see change in Routing table of R1. Area range command summarizes range and only work on Border Routers.
5. See Results by using Show ip route; show ip protocols
6. Dubug ip ospf adj and Debug ip ospf events

Rip Passive interface

8/26/2013

 
passive-interface command is used to block RIP broadcasts on an interface connected to a subnet of a RIP-enabled network. In simple words, Passive-interface command is used in all routing protocols to disable sending updates out from a specific interface. A RIP Passive Interface in a nut shell prevents the RIP routing process from sending multicast/broadcast updates out a specified interface. A RIP Passive interface however does not block unicast updates. Keep in mind a Passive Interface DOES NOT block multicast/broadcast updates therefore the router would still process received RIP updates
Tasks:
Configure IP addresses as per diagram
Configure Rip on all networks
Configure R3 Fast Ethernet 0/0 interface to start Rip unicast
Debug by using following commands.
show ip route
show ip route rip
sh ip protocol
debug ip rip events
debug ip rip database
