interface-range config inheritance change
There are large ex4300 stacks with hundreds of access ports. The bulk of these ports are access ports on a single VLAN, but there are exceptions sprinkled about. With Junos 13.2, the exception...
View ArticleRe: Q-in-Q to virtual router instance?
A rather crude solution to this is to loop two of the ports; 1 as a 802.1ad access port (single tagged), 1 as a 802.1q trunk port (single tagged). Rember to disable spanning tree on one of these ports...
View ArticleRe: Virtual-chassis qfx5100 Switch Oversubscription
The usual answer is to go leaf - spine rather than full mesh. In order to guarantee 2:1 oversubscription in a 7 switch fabric, you'd have to get 2 spine switches (QFX5100-24Q), and run 3 uplinks out...

Agree with this response. To decrese potential oversubscription is a ring, only options are decrease the inputs or increase the ring bandwidth, if possible.
