Os novos Roteadores MSR da HP possuem suporte para a configuração em IRF. O IRF é uma tecnologia que permite transformarmos diversos Switches ou Roteadores físicos em um único equipamento lógico. Todos os equipamentos serão visualizados como uma única “caixa”, aumentando a disponibilidade da rede.

A recomendação é efetuar o IRF com equipamentos da mesma família e modelo, mas há dispositivos que suportam equipamento da mesma família, mas com diferentes modelos. É bom pesquisar caso a caso.

O cenário abaixo foi construído utilizando o simulador HCL utilizando 2 Roteadores em IRF conectando um Router-Aggregation com um Switch 5820.

Configurando o IRF

Segue abaixo o passo-a-passo da configuração:

1º altere o irf-member ID do segundo Roteador (por padrão o member ID é 1) e o priority de cada equipamento para eleição do Master (vence o maior valor).

R1
<ROUTER>system
[ROUTER]irf priority 31

R2
<ROUTER>system
[ROUTER]irf member 2
[ROUTER]irf priority 30

Configurando as IRF-port

R1
[ROUTER]irf-port 1
[ROUTER-irf-port1]port group interface GigabitEthernet 0/0
[ROUTER-irf-port1]quit

R2
[ROUTER]irf-port 2
[ROUTER-irf-port2]port group interface GigabitEthernet 0/0
[ROUTER-irf-port2]quit

Habilitando o IRF

R1
[ROUTER]chassis convert mode irf
The device will switch to IRF mode and reboot.
You are recommended to save the current running configuration and specify the configuration file for the next startup. Continue? [Y/N]:y
Do you want to convert the content of the next startup configuration file flash:/startup.cfg to make it available in IRF mode? [Y/N]:y
Now rebooting, please wait...

R2
[ROUTER]chassis convert mode irf
