I'm willing to try all the
Segment Routing implementations one-by-one in
XRv 9000 Router. Each time I have a specific implementation for
SR-ISIS ... etc.
The problem is in IOS XR when the configuration is finished, you need to commit that configuration. How can I save the initial default configuration or the initial startup configuration in order to try out all the implementations to avoid ambiguity without losing SSH access to the router and the initial configuration?
