Hey All, I have a bunch of CRS109's around the place which need to be upgraded from 6.40 to 6.42 The one in the living room which basically just does switching went fine. Silly me then went 'rad, lets do the core!'.. And all hell broke loose. After the upgrade, there was no bridge1 automatically created, and all my vlan interfaces were still on ether2-master. After much googling on my phone, and messing about, I have it mostly working, WITH RSTP turned off on the bridge I had to create, and with my VRRP interfaces shutdown, and the IP's from them moved back to the bridges they live on. However things are still quite hinkey, so I'm wondering how things SHOULD be setup post 6.41? So I currently have: + bridge_switchchip - vlan86 - vlan87 - vlan88 - vlan98 - vlan99 - vlan100 - vlan101 - vlan102 All ports are members of bridge_switchchip vlan100, is then a port in bridge_local, as that's our local LAN along with three wifi virtual-interfaces vlan102 is a port in bridge_vlan102, as that's the kids' LAN along with their wifi virtual-interface. it's also in a VRF along with one of the two pppoe dialers on this CRS The switch chip is then also doing a bunch of vlan rules: vlan87: ether1,2,5,6,cpu vlan98: ether1,5,cpu vlan99: ether1,5,cpu vlan100: ethernet1-8,cpu vlan101: ether1-3,ether5-7,cpu vlan102: ether1,2,4,7,cpu And it's also translating vlan100 to native vlan on ether2-5 SO... Pre 6.41, I simply had my vlan interfaces on the master port, had all my interfaces as slaves, and then configured my vlan mappings per port on the switch chip. I now have a bridge with all ports in it, and then vlans under that bridg.e However this seems to be causing problems since I have some of those vlans in bridges themselves? Disabling RSTP on bridge_switchchip let most things talk to most other things, although the kids VRF is not passing traffic as yet. I haven't shoved my own test box onto that network to diagnose it yet though. How SHOULD I be doing this? Should I be creating multiple bridge_switchip_vlanblah bridges, each with its own vlanid set? And only add the interfaces that should have those vlans to that bridge? Or is all this weirdness just a hassle with 6.42.9, and I should come off bugfix, and go to release? Thanks, Damien (Pulling my hair out, and considering pulling the config off my core CRS, and throwing it on the one in the garage that hasn't been upgraded as yet!!!) Damien Gardner Jnr VK2TDG.
