Hello Clarke,
You can use a Linux box with an hexabgp to easely inject as many routes
you want in your lab routers.

I was curious to know if anyone has run into any issues with large
routing tables on an MX causing ISSU upgrades to fail?
On several occasions, I have been able to successfully do an
In-Software-Service-Upgrade (ISSU) in a lab environment but then it
fails to work in production.
I find it difficult to replicate the issue in a lab, since in
production I am dealing with lots of routes as compared to a small
lab. Does anyone have any experience when the backup RE gets its new
software, then reboots, but since it takes a long time to populate the
routing kernel database on the newly upgraded RE that it appears to
timeout?
I have seen behavior like this with upgrades moving from 10.x to a
newer 10.y and from 10.x to 11.y.
