RIP - Conditional Default routing

9/29/2013

 
Task:
Configure routers so that R2 will only originate default information to R3; if 10.1.1.1 is available
!R1 configuration
interface Loopback0
 ip address 10.1.1.1 255.255.255.255
!
interface Serial0/0
 ip address 1.1.1.1 255.0.0.0
no shut
!

 default-information originate route-map match-10


access-list 10 permit 10.1.1.1

route-map match-10
 match ip address 10
 set interface Serial0/1


!R3 configuration

interface Serial0/0
 ip address 2.2.2.2 255.0.0.0
 no shut
!
router rip
 version 2
 network 2.0.0.0





























This command let us do conditional routing as it matches route map name "match-10".

Created Access List 10

Created Route map 10
if ip address in access list 10 matched then interface will be set.

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:

Configuring Rip

Manipulating metric by 5 by using access list 1. Offset list is applied when information gets out of an interface


Manipulating metric by 8 by using access list 1. Offset list is applied when information gets out of an interface





Access list 1 created


























Manipulating metric by 10 hops by using access list 1. Offset list is applied when information gets out of an interface





Access list 1 created

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.
! Configuration of R1

Explanation










Primary Static route with default Administrative distance
Floating Static route with administrative distance of 15
Verification

R1#show ip route
     1.0.0.0/24 is subnetted, 2 subnets
C       1.1.1.0 is directly connected, FastEthernet0/1
C       1.1.2.0 is directly connected, FastEthernet0/0
     10.0.0.0/32 is subnetted, 1 subnets
S       10.1.1.1 [1/0] via 1.1.1.100

Shut down R1 primary route interface and check routing table now

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
