[c-nsp] EX2200 and 3550

[Paul Magee]

Hello,

I've linked a number of EX3200's together with various Cisco switches [3560, 3750, ME3600X off the top of my head] in a former life. I wouldn't necessarily say this is the right way to do it, but it worked for me.

Working from memory, I think the port on the Cisco side was configured as a trunk with the required vlans permitted through. The Juniper was configured in the same way. We used rapid PVST on the Cisco kit and on the Juniper I made an MST instance containing the vlans that were permitted through the trunk. I used a straight through cables to connect them together, and left auto mdix to sort out the mess.

Horribly I've also seen it done just by connecting ordinary access ports to one another to carry a single vlan between the switches. 

In terms of stability, I never saw any issues. Absolutely solid as a rock.

Paul

Has anyone connected a Juniper EX series switch with a Cisco switch (I have
a 3550)?

Do you use a standard crossover cable? MDIX?

Any Layer 2 issues with RSTP and PVST+?

Any specific configuration required to make it work?

Stability?


thanks in advance,

Mike
