Hello,
I'm currently working with MC-LAG to get a test environment running. Unfortunately i cant get my head around one part of the configuration.
I have 4 switches, two at top and the other two connected with those switches by MC-LAG.
Switch A - - - Switch B
| |
Switch C - - - Switch D
Now both stacks are configured with MC-LAG and i've separate interfaces for the ICCP (ae1) traffic and ICL-PL (ae2).
The ICCP traffic is configured to connect with the Lo0 of their neighbour and between Switch A and Switch B there is a routing-vlan with on both sides an IRB interface on VLAN 1.
Now i also have a ICL link, which has a different VLAN and is connected directly by a fibre. On both ends again an IRB interface on VLAN 2.
Both stacks are connected with each other with vlan 100 and this is used for routing purposes (ospf.)
There are also some tagged vlans who are just stretched.
My question is, do i need to configure those stretched vlans etc on the ICL-PL link so that mac-sync etc is done? Or is connectivity between those links enough? For now i've configured those vlans as tagged on the same link as ICCP is connected over (ae1.)
I cannot find a good answer in the Juniper documentation about the ICL-PL link and it's configuration.
