Configuring the Cisco 10000 Series Router for High Scalability
Configuring a Virtual Template Without Interface-Specific Commands
If you configure a virtual template interface with interface-specific commands, the
Cisco 10000 series router does not achieve the highest possible scaling. To verify that the router does
not have interface-specific commands within the virtual template interface configuration, use the test
virtual-template <number> subinterface command.
Including interface-specific commands in a virtual template can limit PPP session scaling. Table 2-7 lists
the interface-specific commands that prevent the Cisco 10000 series router from attaining the highest
possible PPP session scaling.
