IRF with two independent domains

[stranger_83]

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:

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

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
