Why doesn't the config of these 2 interfaces with IP addresses work? Thanks

left-qfx5k       xe-0/0/44 (192.168.10.1)   <--------->     (192.168.10.1)  et-0/0/24:0        right-ptx1k

root@left-qfx5k# show interfaces xe-0/0/44 | display set 
set interfaces xe-0/0/44 unit 0 family inet address 192.168.10.1/32

Change /32 subnet to /30 on both sides..

This is because the /32 subnet only allows a single IPv4 address and all traffic will go directly between the device with that address and the default gateway (If any) from a host perspective. The device would not be able to communicate with other devices on the network since he is basically alone and there is no gateway.

For p2p links use /30 or /31 but never 32 

If this solves your problem, please mark this post as "Accepted Solution" so we can help others too \:)/
