We have 2 sites(Site DL1 and DL2) and each site has 3850 switches (2 switch stack).
DL1 and DL2 have different separate network. but there is a requirement that DL1 should be able to access a new network (10.98.x.x) that is connected to DL2. DL1 and DL2 will be connected to each other through a fiber uplink port (Gi1/1/1 and Gi2/1/1) on each stack.
What is the best way to achieve it. Should i create a port channel on 2 port with an IP (192.168.1.1 & 192.168.1.2) and do routing.
Thanks in advance for the suggestions

How does DL2 know about 10.98.x.x is it directly connected interface on the stack itself a vlan svi or is 10.98.x.x on a directly connected to another device hanging off DL2
does DL2 already connect to DL1 in anyway, is either device currently doing routing , you have the option to either run straight layer 2 trunk or access port with just that vlan or you could run ip routing if your stacks support that as you suggested, but ye I agree run a port-channel for redundancy , and split the po across both switches in the stack no matter what way you connect l2 or l3 , whether you switch or route I suppose is personal decision, switch can extend the broadcast domain for the subnet but its simpler to configure maintain and can be faster , routing though has its advantages as well

Hi Mark,
Thanks for the reply
10.98.x.x will be connected to DL2 via another device. DL2 will use (192.168.34.1 & 2) to connect to another router to reach 10.98.x.x. Currently DL1 and DL2 do not connect to each other. I have attached a diagram for better understanding.
based on this setup, should i use IP on port channel b/w DL1 and DL2?
