Apologies in advance if this is super-basic question, still learning ISIS.
I'm migrating from Cisco over to Juniper in an environment where all of the switches are running EIGRP, are on a 172.31.255.0/24 segment which is an SVI (VLAN 9) and they reach each other via trunk links. I will be adding Juniper switches into this environment, configuring them to run IS-IS.
My question is, if I plan to keep the same SVI subnet on my Juniper switches and run IS-IS, would I configure a point-to-point statement under the SVI interface or would I make it broadcast since technically it's just one giant VLAN?
My long term plan is to eventually cut down on all the VLAN sprawl and go EVPN/VXLAN but I would like IS-IS as my IGP. Thanks.
