Advanced Redistribution Lab

Objectives:

1. Configure EIGRP and OSPF for the network shown (use OSPF Area 0). Advertise all networks on all routers. Do not implement any summarization features for EIGRP or OSPF. Routes should never be advertised in both OSPF and EIGRP routing domains.

2. Enable full, mutual redistribution on R2 and R3 between OSPF and EIGRP. The 10.4.0.0/24 and 10.4.1.0/24 subnets should have a seed metric of 100 and an OSPF tag of 10 while the 10.4.2.0/24 and 10.4.3.0/24 subnets should have a seed metric of 200 and an OSPF tag of 20. All other subnets redistributed into OSPF should have a seed metric of 300 and an OSPF tag of 30. OSPF routes redistributed into EIGRP should have a seed metric of BW: 400 DLY: 20 REL: 255 LD: 1 MTU: 1500 and a tag of 40. Finally, external OSPF routes should not increment their metric as they pass through the OSPF domain.

3. Ensure the 10.4.4.0/24 network does not reach the OSPF routing domain.

4. Enable filtering using the assigned route tags to ensure redistributed routes do not cause any looping issues.

5. R3 has the preferred route to reach the 10.1.0.0/24 network. Ensure routers prefer this path over the path from R2.

Simple Redistribution

 

 

Objectives:

1. Configure EIGRP and OSPF for the network shown. Advertise all networks on all routers. Do not implement any summarization features for EIGRP or OSPF. Use Area 0 for the OSPF portion of the network and configure all Loopback interfaces on R3 as a point-to-point OSPF network.

2. Enable full redistribution between OSPF and EIGRP, implementing any necessary seed metrics to ensure all routers are able to see all routes. OSPF external routes should not increment their metric as they propagate the network.

3. Implement distribute-list filtering in such a way that the OSPF domain only sees odd numbered loopback networks coming from R1. Any even numbered subnet (including physical networks) should be hidden from OSPF.

4. Implement route-map filtering in such a way that the EIGRP domain does not see routes with a more specific subnet mask than /24.

OSPF Special Area

 

GNS3 Steps.pdf

Objectives:

1. Configure basic OSPF for the network shown. Advertise all networks attached to each router into OSPF using the simplest method available. To inject external networks into the OSPF domain, redistribute the static routes on R1. These routes should be marked as type E1.

2. OSPF should never form neighbor relationships on any interface where other OSPF routers do not exist (as shown in the diagram).

3. All routers in Area 0 should use MD5 authentication for OSPF neighbors. Routers in Area 23 should be configured to support clear-text authentication for OSPF neighbors. All keys should be set to the passphrase ‘cisco’ (without quotes).

4. Routers in Area 45 are limited in their capacity and should not receive routes for networks outside the OSPF system. These routers should reach the external network using a default route which cannot be configured statically.

5. Routers in Area 23 must not receive any Type 3, 4, or 5 LSAs from the rest of the OSPF network. These routers should reach the external network using a default route with an initial OSPF cost of 100.

6. When this exercise is complete, all routers should be able to reach (ping) every route in the OSPF routing table

OSPF over Frame Relay ( Point to Point , Point to Multipoint NBMA)

I hope this blog will help for easy referencing in Labbing framrelay with OSPF .when i doing first time Labbing , router uses as framerelay switch hv some mismatch configuration.
I hope this information will be informatics for CCNP Route Lab.All received are copied from
CCNP Route Lab manual . Just Only copied the most important role of this lab.

Objectives

 

1. Configure OSPF over Frame Relay.
2. Use non-broadcast and point-to-multipoint OSPF network types.
3. Modify default OSPF timer

 Step 1: Configure Frame Relay and addressing on the HQ, EAST, and WEST routers.

 Step 2: Configure the Frame Relay switch

 Step 3: Configure OSPF network type NBMA.

 On EAST and WEST, change the Frame Relay interfaces to have OSPF priority 0. This priority ensures that HQ becomes the DR.(For Point to Point Type)
Configure neighbor statements on HQ pointing toward EAST and WEST.And EAST and WEST also Pointing toward to HQ .

Step 4: Change the network type to point-to-multipoint


 Step 5: Change OSPF timers.

Q : What are some disadvantages to changing the timers if they are not tuned correctly?

Ans : If timers are not tuned correctly, there are many negative side effects. Hello packets can saturate a slower link or overload a slower router. Route instability and route flapping can occur from bad timers having an adjacency come up and down. If timers are tuned to take too long, reconvergence of a network after topology changes can be slower.

Challenge: Minimal Hello Intervals

Configure the Fast Ethernet link between EAST and WEST to lower the convergence time using the ip ospf dead-interval minimal hello-multiplier multiplier command. This command sets the dead interval to 1 second. Hellos will be sent at the rate of multiplier per second. 

Use the following Tcl script to verify connectivity to all addresses in the topology.
 
HQ# tclsh
HQ(tcl)#
foreach address {
10.1.1.1
10.1.2.1
10.1.3.1
10.1.123.1
10.1.123.2
10.1.123.3
10.1.23.2
10.1.23.3
} {
ping $address }

OSPF Virtual Links and Area Summarization

CCNPv6 ROUTE
Chapter 3 Lab 3-3, OSPF Virtual Links and Area Summarization

I purposed  this blog post for easy referencing who Labbing CCNP OSPF route .All Sources is according to CCNP lab manual . I'm also a learner who trying to get CCNP Certi . Cheer All bro .

Objectives

1. Configure multi-area OSPF on a router.
2. Verify multi-area behavior.
3. Create an OSPF virtual link.
4. Summarize an area.
5. Generate a default route into OSPF.

Step 1: Configure addressing and loopbacks.

Step 2: Add interfaces into OSPF.

 Note: The default behavior of OSPF for loopback interfaces is to advertise a 32-bit host route. To ensure that the full /24 network is advertised, use the ip ospf network point-to-point command. Change the network type on the loopback interfaces so that they are advertised with the correct subnet.

 Step 3: Create a virtual link

Q : What would happen if routes could pass between areas without going through the backbone?
Ans :  Routing loops might occur because any route could get advertised to different areas. By passing through the backbone, type 3 LSAs are generated by their respective areas and not sent back in
 Q : When are virtual links useful?
Ans : Virtual links are useful when there needs to be a temporary extension of the backbone, either because the backbone became discontinuous or a new area got added onto an existing area. 
Q : Why are virtual links a poor long-term solution?
Ans : Virtual links are a poor long-term solution because they add processing overhead and basically extend the backbone area onto routers where it might not belong. They can also add a lot of complexity to troubleshooting.

Step 4: Summarize an area

 Loopbacks 100 through 103 can be summarized into one supernet of 192.168.100.0 /22.

Step 5: Generate a default route into OSPF. 

 You can simulate loopback 30 on R1 to be a connection to the Internet. You do not need to advertise this specific network to the rest of the network. Instead, you can just have a default route for all unknown traffic to go to R1. 


Use the following Tcl script to verify connectivity to all addresses in the topology

R1# tclsh
R1(tcl)#
foreach address {
10.1.1.1
10.1.2.1
10.1.3.1
10.1.12.1
10.1.12.2
10.1.23.2
10.1.23.3
172.30.30.1
192.168.100.1
192.168.101.1
192.168.102.1
192.168.103.1
} {
ping $address }

Challenge: Configure OSPF Authentication

Configure OSPF MD5 authentication on the link between R2 and R3, using key ID 1 and the password cisco. Record the commands used below.

Enter the following configuration commands on R2 and R3:
ip ospf authentication message-digest
ip ospf message-digest-key 1 md5 cisco
