I'm looking for a small layer 3 switch with 2 x 10G interfaces and which
supports unnumbered point-to-point ethernet subinterfaces.
Application is a native ethernet access network, with customers
presented on different tagged VLANs. No PPPoE/BRAS. Using /31
point-to-point subnets would be trivial but would burn 50% of v4 address
space, so I want to be able to give each customer the next available
/32. Finding compatible CPE is not a problem.
What I've found so far:
* Juniper feature "unnumbered ethernet" is disabled on any switch
smaller than EX9200 :-(

* Cisco feature "IP unnumbered for VLAN-SVI interfaces" is not on the
Cat 3750-X switches, but looks like it is on the 3650 and 3850 with IOS XE

Does anybody know of any other options? A real router would also be
considered if it's in the compact L3 switch price bracket.
Thanks,
Brian.
