route and redirection between Ubuntu 24 (srv1) - s3048 - s5248f - 10xR750 with ubuntu 24
I have connected s3048 to ubuntu 24 server, lets call it srv1, connected s3048 to s5248f, set up vlan on s5248f with 10 R750 - now following works: I can ssh from srv1 to s3948, I can ssh from s3048 to s5248f, I can ssh from R750 to s5248f, I can ssh from R750 nr1 to R750 nr2 or 3 etc - I need to ssh from srv1 to R750, also to ssh from s3048 to R750 servers

Hello,
on the srv1 did you add routes to the R750 networks?
On s3048, ensure it has routes to the R750 networks via s5248f.
This is an advanced network configuration we have a dedicated configuration team that can help you.
Thanks
