Configuring Redistribution

Refer to the Section 3.1 for Configuration Guidelines and Figure Topology 1 for Testing iS5Com RIP for the Setup. The prerequisite configuration needs to be done in the switches (ISS 1 and ISS 2) before configuring RIP.

To configure Redistribution, execute the following commands in the switch ISS 1.

Type the following:

  • Enter the Global Configuration Mode in ISS 1.
iS5comm# configure terminal
  • Enable RIP globally in the switch ISS 1.
iS5comm(config)# router rip
  • Enable RIP over the interface VLAN 1 (IP address 10.0.0.1/16).
iS5comm(config-router)# network 10.0.0.1
  • Configure the redistribution of static routes into RIP domain.
iS5comm(config-router)# redistribute static
  • Exit from the Router Configuration Mode.
iS5comm(config-router)# end

  4. View the RIP route entries for the static routes added in ISS 1. Static routes added in ISS 1 with metric 3 are redistributed into the RIP domain. In ISS2, view the redistributed static routes with metric 4 using the following command.

    Type the following:

    iS5comm# show ip rip database
    10.0.0.0/8  [1]        auto-summary
    10.0.0.0/16 [1]        directly connected, vlan1
    50.0.0.0/8  [4]        auto-summary

    iS5comm(config-router)# end
  6. View in ISS2, the RIP route entries for the static routes added in ISS 1, which are made as unreachable with metric as infinity (16). Static routes added in ISS 1 are redistributed into the RIP domain by using the following command.

    Type the following:

    iS5comm# show ip rip database

    iS5comm# show ip route
    C 10.0.0.0/16 is directly connected, vlan1
    C 30.2.2.0/24 is directly connected, vlan3

Redistribution of Connected Networks

Refer to the Section 3.1 for Configuration Guidelines and Figure Topology 2 for Testing iS5Com RIP for the Setup. The prerequisite configuration needs to be done in the switches (ISS 1, ISS 2 and ISS 3) before configuring RIP.

Use redistribute connected command to make sure that connected networks between the switches are redistributed as well and have full reachability.

Note that the redistribute connected command will just redistribute all connected networks regardless of their involvement in the redistribution process.

If we want to filter the redistributed connected networks to include only the connected networks between the switches, use a route map to filter them.

For connected redistribution, execute the following commands:

Type the following:

  • Enter the Global Configuration Mode.
iS5comm# configure terminal
  • Enable RIP globally in the switch ISS1.
iS5comm(config)# router rip
  • Enable RIP over the interface VLAN 1 (IP address 10.0.0.1/16).
iS5comm(config-router)# network 10.0.0.1
  • Use option connected to ensure that the connected network between the switches are redistributed.
iS5comm(config-router)# redistribute connected
  • Exit from to the Router Configuration Mode.
iS5comm(config-router)# exit
