[c-nsp] Maximum supported number of Virtual-templates

[Oliver Boehmer (oboehmer)]

Yasser,

if you're doing PPPoATM or some other PPPoX scenario, you might want
consider applying the appropriate policy-maps (which need to be defined
locally on the router) via Radius attributes
"lcp:interface-config=service-policy..." or
"ip:sub-policy-In=XXX"/"ip:sub-policy-Out" (the latter commands are
supported on virtual-access sub-interfaces) instead of defining a
virtual-template per customer.

You would still need to maintain two configurations (Radius profiles and
local policy-maps), but since this would likely to be the case with
virtual-templates as well, you can reduce the router configuration by
using the same vtemplate for all customers.

Please also bear in mind that there is a maximum number of
policy-maps/class-maps on the router (don't know it offhand, something
like 1024, not sure), so you want to re-use policy-maps as much as
possible across your customer base if you terminate many customers on
the box.
