Seems odd no jumbo frames . Iirc you need to support > 1500 in order to do mpls tags which is jumbo; every switch I've encountered has different max port mtu tho so you may need ro play to discover. What sort of failover times are you getting? I've encounterd mpls ldp/sdp setups which are slower than an l3 based failover... test and compare if you can.

We've got a mix of Brocade MLX and Juniper MX chassis on our network and I'm working on getting VPLS standing up between them with LDP signalling (RSVP underneath for the base MPLS). Everything seems okay except for the odd quirk (Brocade can't do OSPF with jumbo frames, Juniper doesn't automatically strip VLAN tags when sending into the VPLS cloud) but otherwise it's standing up.

I just wanted to see if anyone else has this sort of setup, and whether there's anything I should be looking for that might trip me up? My logic so far is as long as I don't try and make the Brocades do BGP then I should be safe, is this about right?

Thanks in advance

Hi Sam We've done quite a bit of work with Juniper MXes talking to Brocade MLXes using OSPF. We've been bitten by MTU mis-matches and Jumbo frame issues and solved all of our issues to my knowledge. We're now running MTUs of 9100 ish (I forget the exact number) on our OSPF area 0 interfaces on both Brocades and our MXes. I haven't done any work with VPLS between Brocades and Juniper MXes. I'm about to head out now but feel free to email me tomorrow on dave(a)staff.inspire.net.nz if what I've been saying sounds useful and I'll try and help.
