​​Summary:

1. Add a secondary connection to the Cereal router and verify equal cost load balancing is working

2. Modify the bandwidth on the secondary line to 1Mbps. Adjust EIGRP to enable unequal cost load balancing

1. Add a secondary connection to the Cereal router and verify equal cost load balancing is working

Eggs:

  int s2/0
  ip address 172.16.5.1 255.255.255.0
  no shut

  router eigrp 90

  network 172.16.5.1 0.0.0.0

 

Cereal:

  int s1/1
  ip address 172.16.5.2 255.255.255.0
  no shut

  router eigrp 90
  network 172.16.5.2 0.0.0.0

2. Modify the bandwidth on the secondary line to 1Mbps. Adjust EIGRP to enable unequal cost load balancing

 

 

Default interface bandwidth:

Eggs:

  int s2/0
  bandwidth 1000

Cereal:

  bandwidth 1000
  do sh int s1/1

  clear ip eigrp neighbors !-----------restart eigrp process

  clear ip route !--------------------------wipe the routing table

 

Now, it becomes single path again:

Eggs:

  router eigrp 90
  variance 2 !--------------- every packet sent to s2/0, sending 2 packets to s1/3
 

Cereal:

  router eigrp 90
  variance 2  !---------------every packet sent to s1/1, sending 2 packets to s1/0

 

Now, check again:
