We have 200 node network with no vlans (small private company which grew quickly)
All nodes / devices/ PCs etc spread evenly over 6 Dell 5448 switches with no regard for department, location nor use.
(1) L3 is 6248 - We have added 6248 to route VLANs (everything is on VLAN 1 still - i.e. no tagging)
(2) L2 multiple VLANs per switch - Best case, 2 vlans per 5448
(3) Trunk / General uplink from L2 5448s using LAG (ports 44, 45) - expected to have all tagged traffic but since this will be a conversion / migration on a 24x7 ecommerce network, we thought we would have to make the uplinks between 5548s and 6248 General and change to Trunk later
(4) during conversion, all trunk/general uplinks will have multiple tagged vlans as well as untagged vlan1 traffic
(5) We know we should set each VLAN gateway IP to the 6248 IP address servicing the VLAN, but can't decide how to do this with no one-to-one match of VLAN to uplink LAG
Questions on 6248
Q1: would we use "Bind IP Subnet to VLAN" on the 6248 to setup the routing between VLANs or do we have to set VLAN membership per LAG ?
Q2: would we expect to be able to ping the VLAN gateway IP configured in the 6248 from a down link host / node / PC tagged for the same VLAN ?
Any suggestions would be most appreciated.
