Extend template filter range_to_regex
Closed, ResolvedPublicFEATURE REQUEST
Actions

Description

The template filter range_to_regex should accept and correctly detect list arguments

For now, the values for the lists are not correct

>>> range_to_regex('2000-3000')
'(200\\d|20[1-9]\\d|2[1-9]\\d{2}|3000)'
>>> 
>>> 
>>> range_to_regex(['2000-3000', '3002-3005'])
['2000-3000', '3002-3005']
>>>

As the use case, it is T5057, for example, if we have several vlan-range interfaces
For example:

set service ipoe-server authentication mode 'noauth'
set service ipoe-server interface eth1 client-subnet '100.64.24.0/24'
set service ipoe-server interface eth1 network 'vlan'
set service ipoe-server interface eth1 vlan '2000-3000'
set service ipoe-server interface eth1 vlan '3002-3005'

We expect one regex for all listen to interfaces

If we add vlan to range we get error

set service ipoe-server authentication mode 'noauth'
set service ipoe-server client-ip-pool name POOL1 gateway-address '192.0.2.1'
set service ipoe-server client-ip-pool name POOL1 subnet '192.0.2.0/24'
set service ipoe-server interface eth1 vlan '2000-3000'
commit
set service ipoe-server interface eth1 vlan '50'
