I'm prepping an EX4600 for use as a distribution switch. This will uplink to our core router, which is an MX960 VC. EX4600 is running 14.1X53-D30, and the MX960 is on 12.3R8.7. We have a mix of L2 and L3 connections, with roughly 15 vlans that span to the EX and another 10-15 that will exist as L3 and route on the EX. Long term all the spanned vlans will be removed and migrated to local L3 vlans inside several VRFs on the EX. So looking to the future, I see the link between these two devices as having a few routed connections for the VRFs only with nothing spanned/bridged.
I would like to configure two units on the link, a unit 0 as family ethernet-switching/bridge for the spanned vlans, and another unit in family inet/inet6 for the L3 link. I can get the connection configured and up, and can see MACs and ARPs in the appropriate places for the spanned vlans, but those devices will not ping and traffic is intermittent at best. There is no issue with the L3 traffic. I'm betting it's some kind of mismatch between the configurations, but I can't figure out what it is. I've tried a couple of changes as far as vlan-tagging and encapsulations but can't get those spanned vlans to function properly.
If anyone has a suggestion I'd love to hear it. If not, I'll just be going to a single unit with everything bridged including my L3 point-to-point (which works normally on the EX4550-to-MX960, and I'm assuming will work correctly here. Configs for the interfaces are below. Thanks.
