Lab 32: GLBP (Gateway Load Balancing Protocol)

Task

Topology

1. Configure IP Address as per given in topology.
2. Configure Eigrp as per given in topology.
3. Configure PAT on R1.
4. Configure GLBP on MLS1, MLS2, MLS3 & MLS4.
5. Make sure MLS2 is become AVG (Active Virtual Gateway) and rest of all become AVF (Active Virtual Forwarders)
6. Use GLBP authentication "N#!W@xL@B".
7. Make sure All PC's are able to ping www.netwaxlab.com and blog.eincop.com

Solution

Task 2: Configure Eigrp as per given in topology.

R1
==

router eigrp 100
 redistribute static
 network 192.168.1.0
 no auto-summary
 exit

MLS1 to MLS4
============

router eigrp 100
 network 0.0.0.0
 no auto-summary
 exit


Task 3: Configure PAT on R1.

R1
==

ip route 0.0.0.0 0.0.0.0 172.54.29.1

ip access-list extended NAT
 permit ip 192.168.1.0 0.0.0.255 any
 permit ip 192.168.200.0 0.0.0.255 any
 exit

int f0/0
 ip nat outside
 exit

int f0/1
 ip nat inside
 exit

ip nat inside source list NAT interface FastEthernet0/0 overload


Task 4: Configure GLBP on MLS1, MLS2, MLS3 & MLS4.

MLS1 to MLS4
============

int f1/2
 glbp 1 ip 192.168.200.254
 glbp 1 preempt
 exit


Task 5: Make sure MLS2 is become AVG (Active Virtual Gateway) and rest of all become AVF (Active Virtual Forworders)

MLS1
====

int f1/2
 glbp 1 priority 190
 exit


MLS2
====

int f1/2
 glbp 1 priority 200
 exit

MLS3
====

int f1/2
 glbp 1 priority 191
 exit

MLS4
====

int f1/2
 glbp 1 priority 192
 exit


Task 6: Use GLBP authentication "N#!W@xL@B".

MLS1 to MLS4
============

int f1/2
 glbp 1 authentication md5 key-string N#!W@xL@B
 exit

 
Task 7: Make sure All PC's are able to ping www.netwaxlab.com and blog.eincop.com

Note: Provide Glbp Virtual IP address 192.168.200.254 to all the Pc's Gateway so that they can communicate with MLS.
