IRF with two independent domains

Hello!

 

I need to help with IRF scheme on 5700 and 5800 series. One domain is with 5700 series switches, the next one is with 5800. I plan to build two domains with LACP link between them. The scheme will look like this:

 

Two_IRF

 

I have the next questions: will all four  links between two domains must be set as one LACP trunk with LACP MAD? Is there any configuration examples for such scheme? I `ve found only descriptions for one domain with two or four switches but never have seen my case. Please, help

Re: IRF with two independent domains

Hi there,

Yes, all links that belong to the same IRF domain will be in the BAGG.

Here is a sample config, you need to ensure each IRF domain uses a unique domain #

 

 sysname 5800-IRF
#

irf-port 1/1
 port group interface Ten-GigabitEthernet1/0/25

#
 irf domain 1

#

interface Bridge-Aggregation1
 port link-type trunk
 port trunk permit vlan all
 link-aggregation mode dynamic
 mad enable   

#

interface range GigabitEthernet1/0/X to GigabitEthernet1/0/Y
 port link-mode bridge
 port link-type trunk
 port trunk permit vlan all
 port link-aggregation group 1

 

 

===============================

  sysname 5700-IRF
#

irf-port 2/2
 port group interface Ten-GigabitEthernet1/0/25

#
 irf domain 2

#

interface Bridge-Aggregation1
 port link-type trunk
 port trunk permit vlan all
 link-aggregation mode dynamic
 mad enable   

#

interface range GigabitEthernet1/0/X to GigabitEthernet1/0/Y
 port link-mode bridge
 port link-type trunk
 port trunk permit vlan all
 port link-aggregation group 1

 

 

Thanks,

Daryl
