Dear Team ,
I have customer that has branches which has different subnet mask for 192.168.0.0/16
some of their branches use /25 , some /26 , /27 etc .
we have 2 hubs (DC and DR).
As checked template can config only one specific subnet-mask for one template for example /25 or /26
so to accomplish this , i create template based on subnet-mask . Example : template/25 , template/26 ... then assign each branch based on that.
+problem comes when adding this.
All routes to each branches are getting spinning status. so i opened many cases that can't solve my problem , only one engineer that he can support me and solve the problem back to normal to what i desire. He said route get status spinning cuz of template summary at the backend.
so , he removed the L3 template summary change in the back-end ,
Therefore i want to ask :
Is template summary enable by default ? so when new customer , do i have to open case and tell them to disable all the time ? Can you help confirm ? as this is at the backend , i can't config that , only TAC engineer.
If you are referring to having multiple templates with overlapping subnets not being allowed by default - then yes, only support can disable this check.
Your design is not typically - typically networks have the same size LANs at each spoke?
With such a large amount of private address space do you know why they used prefixes small then /24?
