Hello @TimeOut ,

a cisco 1900 is a software based router and not a multilayer switch

for this reason there is no SDM template concept and there is no TCAM size to deal with.

You need to look at the output of show version

This will give you the total amount of RAM memory.

The max number of routes depends on the RAM size in a software based router.

Each prefix will be in the IP routing table and in the CEF FIB table.

Also the CPU power is important for CEF table refresh.

In any case a Cisco 1900 is far from being able to support a BGP full table of more then 700,000 routes

I would expect it to be able to handle 10,000 routes to 20,000 routes.

Hope to help
